And knowledge of performance is perhaps the most safety-critical knowledge a pilot must posses. Phil Croucher sets the record straight. 57 You can count on K-MAX. Many missions require efficient heavy lifting. One helicopter does it better than the rest. Conceived and designed to perform repetitive external lifting, the K-MAX excels, lifting 6,000 pounds while delivering unmatched performance and reliability. What’s more, K-MAX has the highest availability rate and the lowest maintenance man-hour per flight hour of any helicopter in its class. A fleet of hard-working K-MAX helicopters will be ready to respond to the most difficult missions — from delivering supplies to clearing debris or rebuilding — any where, any time. You can count on it. Kaman Aerospace · Connecticut USA · 1-860-243-7006 · [email protected] f r o m t h e e d ito r PUBLISHER Neville (Ned) Dawson The saga of Night Vision Goggles and the civilian industry seems to be an ongoing saga. It seems that some regulators EDITOR cannot make up their minds b y m a r k o g d e n Mark Ogden as to what is needed or how things should be implemented. Mike deputy editor Atwood, probably the most recognized Rob Neil promoter of, and trainer in, the civilian use of NVGs has been deeply involved in the US EDITORs regulatory development of this aid to flying. Aaron Fitzgerald He recently lashed out at the FAA regarding its recently issued Handbook Bulletin for Air legal EDITOR Transportation (HBAT) which sets guidelines Robert Van de Vuurst policy for FAA districts and establishes standards for FAA field inspectors. european EDITOR In a letter circulated to many in the Sarah Bowen industry, Atwood pointed out that the HBAT was first going through revision, and he technology editor voiced concerns about the industry not Nick Lappos having an opportunity to provide input. He said that there were recommendations safety editor forwarded for review and implementation Phil Croucher into the HBAT, but not one of them was included. Another issue was that the FAA Maintenance editor had increased the NVG Initial Pilot training Russell Goulden time from five to eight hours representing a sixty percent increase in the training. This ITALIAN CORRESPONDENT is interesting because, as Atwood highlights Damiano Gualdoni in his letter, in the eight years that the NVG program has been running, there has not scandinavian CORRESPONDENT been one accident in the US attributable Rickard Gilberg to the use of NVGs. Among other issues he noted, “One of the major problems that PROJECT MANAGER the FAA refuses to admit, is that industry Cathy Horton has taken the lead and has developed the expertise and experience for civil NVG proofreader operations.” He also says that because Barbara McIntosh an individual flew NVGs in the military, “this does not give them the knowledge DESIGN base, operational experience, and absolute Graphic Design Services Ltd qualifications for civil NVG operations, especially if they have never flown civil PRINTING operations.” Print World Hallelujah! This, I believe, has been one of the biggest problems with the introduction of NVGs – the military EDITORIAL ADDRESS influence.

Whilst every care is taken In Australia, the industry has been Oceania Group Intl accept no responsibility for struggling to get the country’s regulator, submitted material. All views expressed in HeliOps the Civil Aviation Safety Authority (CASA), are not necessarily those of Oceania Group Intl. to come to a realistic determination on the introduction of NVGs to civilian operations there. Fortunately, after many false starts over the past few years and having hopes raised then dashed by the authority as it continually moved the goalposts, there may now be some semblance of reasonableness arising. CASA in consultation with an HAA NVG Industry Working Group finally followed the intent of the CASA CEO’s (Bruce Byron) vision of regulatory development (despite prevarication by underlings). It seems that NVGs will get the go-ahead soon, and guess what? The training hours will be five in five flights (one in low illumination). This training is also based on a competency standard of flying a helicopter into and out of an unlit pad at night. Additional training (hours) will be required for mission competencies such as rappelling and winching, low time night or IFR pilots. There is an additional minimum 1.5 hours night and instrument training for those pilots without a command instrument rating. Industry sees it as a positive development in that the CEO’s vision prevailed. It seems that even the staid UK CAA may have had a change of heart and is beginning to loosen its approach on the use of NVGs, albeit not before time considering that the AAIB (UK’s accident investigator) first recommended their use for the police air units over three years ago. In New Zealand, two SAR/EMS operators have been routinely operating NVG for all night ops for over a year now. Both did the NVG training course provided by Mike Attwoods’ Aviation Specialties Unlimited (ASU). Many other EMS providers put their crews on this course as well, as did the New Zealand CAA! ASU have run the annual recurrency training for the crews of these two operators. The main issue it seems has been the limited supply of goggles out of the US State Department. The availability of the goggles has meant that NZ has enjoyed a slow and manageable development of practices and procedures with the industry there availing itself with the best available civilian NVG initial and recurrent training, and is now shaping up to conduct its own NZ CAA-approved training and maintenance programs. It is refreshing to see the positive outcome of an authority that monitors the industry, allowing it to develop what is needed while making sure nothing strays too far outside the bounds of reasonableness. Well, with HAI coming up in just a few months and UK’s Helitech less than a year away, the industry is moving along at quite a pace and both these show promise to be exciting industry events. But with that increase in industry activity, comes increased flying hours and a worrisome increase in the number of accidents. Accident rates do not matter; one accident is one too many and hurts the industry in the eyes of the public and if not more importantly in the eyes of the industry’s customers (although their pressure is sometimes a factor in the accident causation).

Both companies currently offer breakthrough products in enhancing situational awareness in the cockpit, and in combination, will offer pilots of the GA market, light trainers and small to medium size business aircraft an integration of enhanced vision and synthetic vision systems. For example, Chelton’s exclusive flight path marker, Highway-in-theSky, and advanced head-up symbology overlaid over the GAViS real time images of an IFR approach will make landings in darkness and low visibility easier and safer. “Express Lane” maintenance Premier Turbines, Dallas Airmotive’s Missouri engine repair and overhaul division, has opened “Express Lane” service for TFE731 and RR 250 engines. The service is up and running. The company has established dedicated areas to handle nonstandard workscopes for TFE731 and Model 250 engines so that operators needing immediate service will not have to compete for priority with other engines undergoing standard overhaul. The Express Lane concept is focused on limited workscopes such as AOG, FOD, special inspections, and ADdriven campaigns where specific areas of the engine are targeted for disassembly, inspection and repair. Dedicated resources including separate work areas, tooling, machinery, equipment, work force and pre-positioned inventory have been established for each product line. Leading Edge laser-marking Leading Edge Aviation has invested in a UV laser wire marking machine which allows the permanent marking of wires without compromising the shielding. Each wire is individually marked to the customer’s exact specifications, this includes, font and font size, and vertical or horizontal orientation. This equipment will also support cataloguing each harness in a data base and allow customers to standardize or upgrade their fleet over time without further expense of duplicate engineering or re-engineering processes. Each harness is accompanied by a detailed schematic and material certification. 4th Generation Rotor Blade The 4th Generation blade development builds on the work done for Sikorsky’s state-of-the-art Growth Rotor Blade (GRB) currently used on the UH-60M and S/H-92. The CH-53K model wind tunnel testing has shown a significant improvement in forward flight efficiency over the GRB. Earlier in the year, similar model rotor hover testing indicated large gains in hover efficiency. The performance of the advanced blade compared to current technology translates directly into increased payload and range. For example, based on model rotor test results, Sikorsky expect range improvements of up to 90nm over the GRB blade for similar S-92A applications. Also, for certain hot-high conditions, the aircraft Max Cruise Speed will increase from 135 to 146 kts. ne w p r o d ucts a n d se r v ices Sky Connect update Free Technical Manual revisions The FAA has issued two STCs revisions, free of charge, to registered owners for the life of MDHI is now providing commercial Rotorcraft Flight Manual to Sky Connect which permit the helicopter.

EXTERNAL LIFERAFTS FOR THE 412 AirCell Certified Apical Industries has Transport Canada approval of the Emergency Replacement Mid-Float with Rafts for the 412. The Apical system includes the patented externally mounted liferaft system integrated in the mid-float. The system is the lightest available system of its type, weighing only 112 pounds (net); a 72 to 133 pound savings when compared to jettisonable liferaft systems. Each mid-float incorporates a twin tube full canopy reversible ten man liferaft (with 15 man overload) and survival kit. The supplied inflation system for the liferafts attaches to existing aircraft fittings and is activated either mechanically from the cockpit or by two externally mounted T-handles. Apical has also received FAA certification for their Tri-Bag Emergency Float System with Rafts and optional automatic water activation on the increased gross weight Eurocopter EC 135T2i/P2i model aircraft. Following the certification of the Increased Gross Weight EC 135 earlier this year, a review of the original drop test data and revised buoyancy substantiation report revealed that the existing design could accommodate the increased gross weight. The FAA has now certified the revisions to the reports that substantiate the suitability of the flotation system at 2,910 kg without necessitating any changes to either the system design or the kit part numbers. The increased gross weight will be included in both the Transport Canada and EASA certification applications. The Tri-Bag system provides the industry’s most stable float platform and is designed to allow the aircraft to be retrieved after water landing by towing. In addition, the external liferafts are integrated into the forward floats, a design that offers not only ease of use but also enhanced safety. The floats may be deployed either manually by a cyclic mounted handle or, optionally, electrically by fuselage mounted water switches. One six-man Liferaft with survival kit is mounted on each of the forward floats. Optional skid extensions are available to allow use of the system with standard skid tubes. AirCell has received FAA certification for the wireless functionality of AirCell Axxess, the company’s flagship satcom system. In addition, AirCell has successfully completed integration testing, allowing operators to add their choice of Inmarsat data connections to AirCell Axxess. AirCell Axxess provides an 802.11b/g wireless hotspot aboard the aircraft, enabling a number of current and future capabilities. When a broadband connection (such as Inmarsat or AirCell broadband) is installed, passengers can use AirCell Axxess’ in-cabin wireless connection to seamlessly operate laptops and other 802.11b/g Wi-Fi devices to surf the Internet, use e-mail, and log on to their corporate VPN’s. Integration testing is also underway on a variety of COTS (commercial off-theshelf) smartphones. More on that system capability will be announced as compatible devices become increasingly available on the consumer market in the coming months. 350FX Honeywell Powered Increased Cord Tailrotor GenerationFX Tailboom Strake Honeywell LTS 101-600A3-A, 350FX1 Applicable to AS 350BA Honeywell LTS 101-700D-2, 350FX2 Applicable to AS 350BA or AS 350B2 GenerationFX Engine Controls GenerationFX VFR Electrical System 200 AMP Electrical Generation 350FX1: 4,960 lbs IGW, 5,200 lbs EGW 350FX2: 4,960 lbs IGW, 5,700 lbs EGW GenerationFX Digital Instrumentation GenerationFX Electro Luminescent Lighting Re-designed Cabin Ergonomics Our 350FX Series STC, based on the AS 350BA/B2 AStar, offers ease of maintenance, improved reliability and increased performance meaning... ...loweroperatingcosts!

Box 6550 Lake Charles, LA 70606 or email to: jfi[email protected] Equal Opportunity Employer Rich Nowland EMS Pilot, Rockford, USA Flying EMS in a Bell 222 is not something that many pilots will get to experience, but for Rich Nowland, since retiring from the Army it has become his day-to-day routine. Rich’s job with Lifeline presents new challenges and sometimes potentially difficult situations. How did you get into flying EMS? I am one of those guys who actually never grew up dreaming of being a helicopter pilot. I joined the army as an 18-year-old kid where I was an infantryman and parachutist. A friend told me about the Army Aviation Warrant Officer Program and I thought that would be fun so I put in an application. After passing all the required tests and the physical I was accepted in 1983. I retired from the Army in 1999 and have been flying civilian EMS ever since. What is your total time on helicopters? Over 6,000 hours. Most of that was in the Army Bell UH-1H, but I’ve also flown the Bell 206, BK117, Schweizer 300, and currently I fly the Bell 222, which I have to say is my absolute favorite. It’s set up as a SPIFR aircraft; it has lots of power and it’s a very smooth ride. What kind of flying have you done during your career? I’ve flown in Europe, South Korea, Thailand, Hawaii and the United States. I’ve done lots of low-level tactical stuff both during the day and at night with NVG. I’ve flown medevac, hoist operations, fighting fires with Bambi Buckets, search and rescue, sling loads and now EMS. I also did some flying for a TV show called “Tour of Duty” . What have you found most satisfying? I really enjoyed teaching tactical flying and instruments to new pilots while I was in the personal profile Army – I’m also pretty satisfied that I am still alive after all that! Have you had any eye-opening moments on an EMS mission? They are all eye-opening moments! The first that comes to mind was a night scene. My pager went off around 22:00 hrs. It was only a seven-minute flight to the accident scene, so en-route we tuned frequencies and contacted the scene command on the radio. They told us they wanted us to land in the eastbound lane of a four-lane highway, and that they would have the traffic stopped. Once over the scene the flight crew and I went to hot mike and circled the accident scene to check winds, the landing area for obstacles, debris and anything that would endanger us on landing. We started our approach with both a searchlight and landing light on from 500 ft. Everything looked good until at 30 ft we heard someone say, “Wires!” I stopped my decent and asked the med crew if they had said that, but they replied, “No, we don’t see any wires.” The nurse was looking out and she told me not to back up – there were wires just a few feet from the tail rotor. I moved the helicopter forward and down and landed. I shut the aircraft down, and went to find the Fire Chief in charge. I have to admit that I wanted to chew the Incident Commander out, but after looking at what he and his volunteer fire department were dealing with (at least five bodies lying in various places around the accident scene), I decided to talk to him later! This was one of the most chaotic accidents I’ve been called out to at night. It just shows that even with a landing zone brief from the hard working guys on the ground, in the chaos of an accident they can miss things that can make it bad for us. Has anything happened in flight that you weren’t prepared for? Yes, I was en-route to a hospital to pick up a patient and we were cruising at 2,000 ft on a very dark night. I had the autopilot on when we heard a loud bang! I immediately grabbed the controls and checked the instruments. Everything was in the green and I didn’t feel anything wrong with the control of the aircraft. I turned off the autopilot and flew for a few minutes to be sure. I asked the paramedic, who flies up front, to shine the flash light out the front windscreen to see if he could see anything. When he did, we discovered that it was covered with blood, feathers and poop! We had hit a Canada goose at 130 knts! His side of the windscreen was completely covered but luckily mine was still clear enough to see through. We landed at the hospital and after checking out the aircraft and cleaning off all the remains of the goose, we found no damage other than a piece of paint missing from the nose. Lesson learned – it seems geese fly IFR at night! Who would have guessed! What is the most challenging thing you have had to do? I did a hoist rescue from a 250 ft grain elevator in Wichita, Kansas, one time, with a single engine Bell UH-1V – a medevac configured Huey. I had to hold a 100 ft hover to lower the medic down to pick up a badly burned patient. The winds were gusting 35 to 45 knts. When we arrived we observed a grain elevator complex with close to 100 silos in one long complex – a half-mile long and 250-feet tall, with a lot of smoke and structural damage. Suddenly a truck pulled into the center of the facility and was unloading when a spark from the vehicle ignited the dust in the facility and literally blew the ends and the center of the complex out. I circled and located the guy they wanted us to rescue and I came to a hover about 100 ft over the patient, who was on the roof. I checked my power and it was well within limits. I then picked a couple of reference points to the front and side of the aircraft to help maintain my position while we lowered the medic. One of my biggest concerns was that the downwash from the helicopter might stir up more dust from the feed that was in the silos and cause another explosion or cause a portion of the building to collapse. I had the medic call me on the radio once he was with the man, and the Crew Chief raised both the medic and the man up and into the Huey. What are your opinions of the EMS industry in the USA? There has been a lot of press about the safety of EMS lately; I think we are moving in the right direction but a lot more can be done, like mandating the use of NVG and autopilots. Training on decision-making and operating the aircraft are also important items. n 15 Ten years of service Celebrating our tenth year of Managing and Operating helicopters The Air Harrods Management service offers 24/7, 365-day operational support including the provision of flight crew, maintenance planning, administration and regulatory compliance.

Here are some rules that are “implied” if not directly stated in every helicopter emergency procedure. w Keep the rotor RPM in the green! Simple enough, but nearly as important as “Don’t forget to breathe.” Find the RPM gauge and put one eye on it in every emergency. You must act decisively, positively, as if your life depended on it. The best immediate control to obey this dictate is the collective pitch, which means keep the rotor from dropping too low or from climbing too high. Use the collective pitch to keep your helicopter flying. Be ready to either lower or raise the collective. How fast? The rotor is your life, and being too slow to lower the collective could mean that you lose control within seconds. Failure to raise the collective during a governor runaway could mean an engine overspeed protection shutdown, followed by dead silence and a guaranteed trip to the nearest forced landing area, instead of a simple flight home in a wounded but very flyable helicopter. In short, failure to keep the rotor happy makes the first emergency only an appetizer for the main course – a bigger, meaner problem. Pilots are reluctant to move the collective up in a runaway, but to do so is almost never bad, because too much power (like being too rich or too thin) is seldom a bad thing. OK, so you climb a bit – see Rule #2. w Keep your altitude if at all possible, and maybe even climb! Second only to rotor RPM, altitude is your friend. Why? Because it can be cashed in later for speed, or glide distance or radio range, or obstruction clearance height. And it can always be lost, since energy is easy to dissipate, yet hard to get, especially when you need it. Perhaps even more to the point, altitude could be irreplaceable in a wounded helicopter that can barely limp home. The tips of ridges are littered with aluminium from aircraft that didn’t quite make it, proving that “didn’t quite make it” is the same as just plain “didn’t make it.” On instruments, a few hundred feet could mean the difference between maintaining the MOCA, or blundering along hoping that you will prove the chart-maker wrong on his estimates. If the chart-maker wins, the noise is deafening, they say. Only when you are on fire in flight or a gearbox is about to seize, is altitude a bad idea, and frankly that is rare enough. w Keep your airspeed! Pilots instinctively slow down during emergencies, the standard back-cyclic and down-collective quick-stop is a natural enough instinctive movement, but many times it is not very healthy. Remember, everything works where you are, and if you slow down too much, you will violate Rule #2. If you must slow down, at least trade the speed for climb, and put that energy in the bank, subject to future withdrawal. Why not slow down? First, you can always slow down later, but you might not have the power to speed up if you have already slowed too much. You climb better, the vertical fin helps in Tail Rotor failures, auto entries are easier (when a little back stick is part of the entry) and the aircraft turns more slowly for a degree of bank, so its flight path is easier to loosely govern while you work out the situation. w Leave the engine controls alone! The number of immediate engine shutdowns caused by checklist-itus is amazing, sometimes leading to that dreadful silence where your helo’s whisper voice tells you that you just shut down the only healthy engine, and bad things are in the immediate future. If I had my way, engine controls would be in the baggage compartment, to be manipulated once the helo was on the ground after the fun. If an engine is dead, what good is flipping its control off in the first minute of the emergency? On the other hand, while rushing to do something fast, what are the chances of you or your sterling co-pilot shutting down a perfectly good engine? Based on the statistics, the odds of throttling a healthy engine are about 10 percent! Auto entries, TR failures in cruise, stabilizing in OEI flight – none of these need to use the engine levers/twist grips at all. w Use your crew! Because we grew up in small singles, we tend to think of ourselves as the lone warrior, pitted solo against nature, and measured by how little we must depend on outside help. Bull! Use anything and everything at your disposal to help out, including that sterling mind in the seat beside you. Once you stabilize the RPM, hold the altitude and airspeed, ask her or him, “So what do YOU think happened?” If you ask it in the right tone of voice, sort of bored and maybe just a little petulant, they will write songs about you in the ready room. If your co-pilot has a bright idea, all the better, because she or he can simply note what happened, without the mind-sapping burden of manipulating the controls. It is surprising how much clearer things appear to your co-pilot. w Don’t smack the ground! Considering that the above all concerns itself with what to do when your helicopter has had something break, please recall that about 30 to 40 percent of all accidents occur when a perfectly controllable, healthy machine is driven into the earth by a crew that didn’t know exactly where the earth was. Since Controlled Flight Into Terrain is the single major cause of mishaps, perhaps we should invert this article and spend 80 percent of the words telling us all how to avoid CFIT. Ah, another column! w Do no further harm! The Hippocratic Oath tells doctors this, and pilots should take heed. Work slowly, precisely and deliberately. If you have a second crew, tell them what you think, ask them what they think... and then decide. n 19 MAINTENAN C E U PDATE 4 Flight logs, maintenance records, historical records. by RUSSELL GOULDEN Changing Registry No, I am not talking about a computer’s registry file, I am talking about removing an aircraft from the register in one country, and re-registering it in another. By convention, an aircraft – whether fixed-wing or rotary – can only be registered in one country at any one time. This is because the country of registration is responsible for overseeing the aircraft, its use, maintenance and airworthiness, and also holds responsibilities with respect to ICAO and accident investigation. It therefore stands to reason that an aircraft cannot be on two different countries’ civil aircraft registers at once. Should you or your organization be considering purchasing an aircraft – regardless of its condition or state of repair – there are some important facts concerning ownership and registration that need to be considered and verified: ➤ In which country is the aircraft registered? ➤ If not currently registered, when was it last registered? ➤ Can it actually be de-registered? Without the actual deregistration from its current registry state (country) the aircraft cannot be registered in another country. If an aircraft has been sitting around unused for some time, there are a number of important things to consider that can have a big impact on how much it will cost to return it to service. Remember time is money! ➤ Do you have all the logbooks normally issued for that type of aircraft? 4 Engine, airframe and propeller logbooks. 4 Modification logbooks. 4 List of hours, cycles and calendar time for all lifed items. ➤ Do you have the aircraft’s complete history? 4 Has it been in an incident (e.g. overtorqued)? 4 Has it been in an accident (e.g. damaged)? 4 Has the aircraft got a monitoring system installed? ➤ Have the appropriate inspections been done and correctly recorded? ➤ Have any components that are subject to TBO or SLL been overhauled or replaced at the prescribed intervals? ➤ Are the logbooks properly filled out with all the appropriate maintenance entries recorded? ➤ For a low utilization aircraft that may have been sitting for years, have any storage inspections been carried out, and if so, have they been recorded in the logbooks? All of the above items need to be considered, otherwise the review of the aircraft in its new destination country for issue of its registration and certificate of airworthiness would disclose such oversights that could delay certification or increase costs – or both. Another important point to consider is an aircraft’s modification state. If local modifications have been made in the country of origin, are all the relevant documents available: modification data, drawings, parts lists, flight manual supplements, continuing airworthiness instructions, approval documents and Form 8130, or Form 337, Form 1 or equivalent? The absence of any of the above usually results in delays in the process. The path I suggest taking, especially when an aircraft is being prepared and shipped, is to apply for an export certificate of airworthiness from the aviation authority of the country of origin. This can be very important when there are modifications to the aircraft that cannot easily be removed or are vital to the aircraft’s configuration (and sale value). The export certificate of airworthiness is a legal document issued by the export country’s airworthiness authority. It is not compulsory from an export point of view, but under some conditions it can be highly desirable from an importing country’s perspective and it generally streamlines the importation process at the destination country and prevents costly delays. Broadly speaking, an export certificate of airworthiness is a document which shows that the exporting country’s civil aviation authority has reviewed the aircraft, records and history. The exporting authority also liaises with the destination country’s authority to agree on any items to be listed. Always remember that if you are a pilot or an engineer licensed in one country, you cannot carry out tasks or fly aircraft registered in a different country without appropriate written approval, authorization or licences. A change of registry is certainly an exercise where it pays to have the legislator squarely on your side. In my opinion, this is best achieved with an upfront approach and a little research. n ➤ Are all the records for the aircraft complete? 21 “Smart Aviation Solutions” • Increases engine life 10 X • 96.7% installed efficiency • Lightweight • Low pressure loss • Reduced drag BK117 SAND FILTER 4 These are 2 of our latest products, there are simply too many to list. 4 We design & manufacture Long Range Fuel Systems, Rescue hoists, Special seating Radomes 4 We are specialists in the design of Modifications for the AS350, AS355, BK117 4 Our latest product is a Hoist System for the SA365 Series designed for the Breeze Eastern 600 Lb HS 20200 www.airwork.co.nz AS350/355 450 LB HOIST • Electrically actuated power boom arm • Ease of stretcher & person ingress • Good skid clearance • Facilitates difficult rescue missions Contact: Russell Goulden Helicopter Projects / Support Manager Airwork (NZ) Ltd, PO Box 72-516, Papakura, Auckland, New Zealand Ph: +64-9-295 2100 Fax: +64-9-295 2106 e-mail: [email protected] safety column Companies as well as individuals are at significant risk in today’s climate of zealous litigation. For example, if something untoward were to happen to a pilot working in a single-engined by PHIL CROUCHER helicopter when there was a twin available, and were that pilot’s spouse to sue the company for failing to provide the safest possible work environment, (i.e. the twin), it would matter little how many expert witnesses the company might produce to prove the safety of a single-engined aircraft.

However, the mere existence of the curve could bias a fly as well as aviation law, jury against a pilot. The unfortunate truth so it pays to consider how a – something many people do not realize – is that juries often disregard the law jury – whose members will and award judgments to suit themselves, which can be a double-edged sword.

While an insurance company might consider it to be to its long-term benefit to keep a good customer happy and pay out, it would be well within its rights to refuse a claim in such circumstances. Is it worth taking the risk? Watch for problems with paperwork, landing sites, equipment used incorrectly or in the wrong environment – or even being in the wrong environment! Try not to take short cuts. The actions we often take to “help the job along” could be entirely misconstrued (or cleverly twisted by a lawyer) in a courtroom. A plaintiff’s lawyer will look at every angle and sue everybody involved, from the manufacturers of an aircraft to the people who flew and maintained it. Carefully consider the value of public liability insurance if you are an independent contractor or “freelancer”. If you are an employee, a master-andservant relationship may be deemed to exist, and might give you some protection. Start thinking up a suitable answer to the statement: “If the passengers weren’t in the helicopter, they wouldn’t have been killed!” Passengers will not (usually) have contributed to an accident, and it’s a hard one to deny, although, presumably, they wouldn’t have been there in the first place if they hadn’t booked their flight! However, you can’t claim their request for a flight as a contributory cause. Please be careful, and not just in your flying! n 23 C O V E R F E AT U R E If all helicopter pilots learned to fly while looking straight down, flying long-line would be a breeze! In reality though, mastering the skills can be tough, and proper training is vital for those who want to become successful, competent and smooth long-line pilots. story by Sarah Bowen PHOTOS by Phillip Knaus & Ned Dawson 26 The widely accredited pioneer of longline operations is Wes Lematta. Lematta developed a technique he called direct visual operational control (DVOC) using a long-line attached to a belly hook. This involved looking out and down at loads attached to a remote hook at the bottom of his long-line. The technique allowed him to move and place external loads precisely with plenty of clearance from obstacles – and created many more work opportunities. The rest, as they say, is history! Lematta and his small operation grew into the present-day Columbia Helicopters – arguably the world leader in heavy-lift external load operations. The DVOC technique is now in worldwide use and is commonly referred to as “vertical reference” – the ability to fly without reference to the usual horizon for orientation. For those pilots willing to accept the risk and inherent danger of flying slowly and hovering out of ground effect (HOGE), long-lining is a challenging yet satisfying flying skill to master. It is all about control, patience and finesse. It’s an acquired skill that is well worth learning if one is to become a true “utility” helicopter pilot. It involves a number of new concepts and tricks of the trade, such as coping with oscillations, suddenly having your personal center of gravity outside the helicopter, and developing the necessary quick reactions and the ability to make decisions if something goes wrong. ABOVE: The specially developed bubble window on the Bell 205 gives Roy Knaus a lot better view of the load below. opposite page: During mountain ops flying the load is only part of the job, the Learning the Ropes pilot must also watch out for obstructions An external load course qualification is no guarantee of a job in the longline industry for a newly qualified commercial pilot, but it certainly provides more opportunities. The right training could well lead to a career in logging, construction, fire-fighting, or one of the many other sectors of the helicopter industry that rely on external load pilots. Pete Gillies, Chief Pilot and instructor with Western Helicopters in California, joined the company in 1972 as a line pilot. “We began teaching long-line in 1975 as the seismic era was beginning. Very few pilots knew how to handle a long-line with smoothness and precision back then. It was an ability that Canadian pilots had mastered through rigorous flight training, but it was a rarely used skill here in the United States,” Gillies explains. “As seismic picked up, the need for excellent long-line skills rapidly increased, and we often found ourselves training two or three students a week.” Western Helicopters is based at such as wires and the cliff face. 27 Powerline Detection System Protection you can hear. One of the greatest hazards in helicopter operations is powerline strikes. Our system senses the electromagnetic field emitted by powerlines, and provides a unique, auditory alert in the pilot’s headset. Pilots literally “hear” their proximity to powerline hazards. The result is the potential for reducing powerline strike accidents and loss of life. Exceedance Warning System Operating limits you can feel. Exceeding operating limits causes premature component failure, higher operating costs and accidents. Our solution is a tactile feedback alert. When operating limits are approached or exceeded, a collective shaker delivers a unique warning. Pilots actually “feel” their way around the helicopter’s operating envelope. The benefits are safer operations, less maintenance downtime, and lower operating costs. (914) 946-9500 www.safeflight.com Pioneering Safety and Performance Since 1946 Rialto Airport, an uncontrolled field 50 miles east of LA (elevation 1,455 ft). From there, its students also train in the nearby mountains, which top out at 11,455 ft, and, if training with a bucket, at a lake located about 8 nm north of the airport. The company conducts most of its training in an MD500D, but it also has a cargo hook-equipped Schweizer 300C. “The 300C costs less to fly, but depending on the density altitude and the weight of the student and instructor, we may not be able to use the 300C during the warmer months. It’s not fun continuously running at near full manifold pressure during this sort of training!” says Gillies. At the airport, Western utilizes a flat area of ground north of the duty runway for long-line training, where a number of “targets” are located for students to practice placing their loads. The practice loads comprise concrete blocks weighing between 30 and 100 lbs, which are carried on slings from 50 to 150 ft long. Students begin with a 50 ft sling and work their way up. Western helicopters uses synthetic rope rather than steel cable for slings to carry various types of loads including power poles, pallets, tanks, pipe, nets and water buckets. Challenges There are three major challenges in learning to carry out accurate, smooth and “happy” long-line flying. The first is learning to fly the helicopter smoothly and precisely while looking straight down, as opposed to looking ahead through the windscreen or at the instruments. The second is understanding and controlling oscillations in the slung load; one must learn how to stop them occurring in the first place, but if they do occur, how to almost instantly quell them. The final challenge is the fine art of feeling one’s way to moving a load the last 30 ft to the target, without losing control of it and having to start all over. Hovering the helicopter has to become second nature – as does “flying the line.” One aspect of long-line flying that many pilots seem to enjoy is the immediate feedback; a load will “tell” a pilot whether he or she is flying smoothly and accurately. However, as with any skill, some learn faster than others. Gillies says that the best pilot ever to graduate from their school was a Swiss mountain guide who took to long-line “like a duck takes to water” – and, he recalls, “she had the techniques mastered in less than an hour!” For those pilots who already have some “500-time,” the average amount of special training required to bring them up to the level of skill and knowledge needed to pass the USFS/OAS “VR” flight test is around five hours. The test requires pilots to be able to hold a load within a 10 ft circle at the end of a 150 ft sling for up to three minutes at a time. While training, flights are limited to no more than one hour as the flying is very fatiguing. There are many factors that have to be taken into account when flying a long-line: rigging the load, sling length, sling material, flight characteristics (which depend on the type of load), safety aspects including those that affect the ground crew, hand signals, radio protocol, density-altitude, load weight, flight path, over-water operations, bucket work, tower assembly, operations in tall trees, around buildings, next to slopes, and so on – it is a long list! After learning the theory and gaining a rating, a pilot really only has a license to learn – there’s nothing like getting first-hand experience on a real job. ABOVE: It takes a special skill to position a load at the end of a 150 ft long-line. opposite page: This Boeing Vertol 234 is one of two that Columbia Helicopters operates in the PNG highlands in support of oil exploration. One aspect of long-line flying that many pilots seem to enjoy is the immediate feedback; a load will “tell” a pilot whether he or she is flying smoothly and accurately. Long-Line To a Career There are few formal ways to gain 29 BV107 as a need arises, at which point you become a 107 command-pilot and can start logging. Eventually you could step up to fire-fighting and construction jobs in the 107, and as your career progresses you are then eligible to be moved up into the Chinook.” The length of the line used varies depending on the particular job, the surroundings (much of the work is around tall trees and large power lines), and the size of the helicopter. If a line is too short, a load can be affected by the downwash and start to spin, which is not good on a construction job. Columbia Helicopters generally uses a 200 ft long-line. This is mainly to ensure that the downwash does not create an unsafe work area for personnel under the helicopter. However, according to Hutchings, Columbia uses a 150 ft line for many of its construction jobs – even with the Chinook – as crews still need to be able to see the load as well as watch for hand signals from the ground crews. The 150 ft line is still long enough to prevent the incredible downwash created by the Chinook from causing mayhem on the ground. Hutchings also has a company called Los Angeles Helicopters in Long Beach, California which is currently putting together a “Professional Long-line Training Course” that will only be taught by professional long-line pilots. If a line is too short, a load can be affected by the downwash and start to spin, which is not good on a construction job. Getting down to business accreditation. Some companies require an external load training course, while others prefer to do the training themselves, starting with shorter lines and easier loads then working their way up. This is the route typically taken by Columbia, which operates a fleet of some of the world’s largest fully certified helicopters. Command pilot Andre Hutchings describes how he started with the company. “I joined Columbia in 1996 as a co-pilot. The criterion then – as it is now – was a minimum of 1,000 hours. Back then you would be hired as a copilot and get sent to wherever Columbia had a need for your services; this could 30 include overseas, Alaska, or pretty much anywhere in the lower 48. Columbia was not concerned if you had any long-line time at all – most of us did not.” Hutchings co-piloted for a couple of years in both the BV-107 and -234, before moving onto flying the “light” ships. Columbia uses 500s, and back then, also used LongRangers. The “light” ships are support helicopters and tend to be used for transporting crews as well as supporting the larger helicopters. “This is where you are first introduced to flying a line,” Hutchings says. “Once you have flown the 500s in support roles for a while, they might move you up into the Anyone thinking about starting their own long-line business needs to comply with certain regulatory requirements. These vary from country to country. David Ekeholm is one of the externalload instructors at Helicopter Adventures Inc., which operates out of Space Coast Regional Airport in Titusville near Orlando, Florida. “One way to get into the long-line industry would be to open your own business. In order to do this in the USA you would need to obtain a Rotorcraft External Load Operator Certificate,” he explains. “You must have ‘exclusive use’ of at least one helicopter that meets the requirements of FAR 133.19; have the sole possession as an owner, or have a written agreement that gives you possession or control of the helicopter for at least six consecutive months.

Whether someone wants to start up on their own, or train for a position with an employer, they will need to demonstrate the necessary competence and knowledge and, depending on which part of the world they will be doing their flying, obtain the required ratings. Helicopter Adventures’ external load training is conducted under FAR Part 61. Ekeholm explains what is involved. “The Part 61 course consists of ten hours’ minimum flying in a cargohook-equipped R22, using different loads and cable lengths, from 12.5 ft to 175 ft. In the initial phases we introduce the student to OGE-hovering, settling with power and vertical reference flying. The subsequent lessons include load control, swing and circle arrest, load pickup and set down, s-layouts and circle-layouts with different cable lengths and at different airspeeds. We try to include as many real-world scenarios as possible, like treeharvest, gully-walking, simulated search and rescue, fire-fighting and quick-stops. After 10 to 15 hours most students have developed an understanding of how the helicopter should be manoeuvred with a load swinging freely underneath the aircraft. It requires a lot more practice before they are really proficient, but by this time they have a general idea of the basic concepts.” One of Helicopter Adventures’ success stories is Jarmo Hillberg, who graduated from their external load course in spring 2000. “After graduating I worked as a flight instructor and commercial pilot in Virginia, where I gained a lot of good experience. I flew with students and performed other types of flight missions such as ENG, power line and pipeline patrol, and sightseeing. In 2002 I went back home to Finland and converted my FAA license to a JAA Commercial; I now fly an AS350B2 for a Finnish company.” Tips from the top There is no substitute for experience, so for aspiring pilots who haven’t yet amassed experience of their own, it pays to listen to those who have been there; here are some top pieces of advice from some established, professional long-line pilots. Brian Pilmer, command pilot at Columbia says, “Be patient and stay focused. Initially the hook will be all over the place, and a pilot’s natural tendency is to chase it. Don’t try to over-control the aircraft. Just try to be as smooth as possible.” Pat Farrand from Whistler in Canada, pilots a Bell 205 and 212.

On the left side, the collective is quite close to the outside of the machine, and you can also lean on your elbow.

Cole says, “Take your time. Don’t hurry. If you hurry, your hook shot can go to hell and you start beating up the guys on the ground or getting hung up in a tree.” Hutchings also gives some excellent words of advice. “Trying to fly a long-line is probably one of the hardest, most frustrating and humbling challenges I’ve faced as a helicopter pilot. I don’t think it’s possible to ever truly ‘master’ flying a line, although I’ve seen some of the guys I work with come pretty close. It’s more a case of good and bad days, and good and bad ‘hook shots’. There are so many variables, but really no hidden secrets to flying a line. There are, however some basic fundamentals that need to be followed in order to at least gain some consistency. “Take your time, and use slow and smooth movements.

As the world wonders how to (affordably) improve the standard of helicopter training to reduce the number of helicopter accidents, Dubai-based Emirates-CAE Flight Training is already providing a solution to benefit everyone – not just those helicopter pilots flying in the UAE. Every day, airlines and aircraft top left: Entry to the Emirates-CAE facility is through the adjoining imposing façade of the Emirates Flight Training Centre. top right: Staggered, multi-level design ensures a flood of natural light into the training centre. Here, the luxurious pilots’ lounge overlooks a row of busy simulators on the level below. above: Senior Bell 412 simulator instructor, Robert Klepper in the 412’s “driving” seat behind the simulator flight-deck. 40 operators continue to face bigger and bigger financial challenges as the margin between profit and loss continues to shrink. There are only a finite number of options for operators wanting to reduce costs and maintain some sort of profitability. The smaller the operator, the fewer the available options to reduce expenditure. Helicopter operators are particularly vulnerable to market forces and in particular the cost of fuel, which is a major expense for every aviation enterprise. Helicopter operators also face hefty maintenance bills to keep their complicated machines airworthy. Another unavoidable, necessary evil is the training budget. Once again, this is a cost that affects helicopter operators more than their (equivalent) fixed-wing counterparts, because helicopters are so much more expensive to operate per flight hour than fixed-wing machines. With rising fuel and maintenance costs sucking the profit-life out of their balance sheets, anything that has the potential to reduce expensive time spent in the air on non-revenue-generating training must be worth serious consideration for helicopter operators. The bigger and more complex the helicopter, the more significant is the training budget for its operator. With this in mind, Emirates-CAE Flight Training (ECFT), a joint-venture company based in Dubai, has taken the lead in providing a JAA and FAAapproved level-D helicopter simulator (the first to be approved by the UK CAA to level-D standards) to cater for the most prolific type likely to benefit from the cost-savings offered by a simulator – the Bell 412. ECFT’s Dubai-based Bell-412 simulator has the potential to save B412 operators thousands of dollars (perhaps millions, depending on fleet size). CAE is the world’s leading simulator manufacturer. With annual revenues of over $1 billion, it operates in 19 countries and currently provides over 80 percent of the world’s simulators. CAE has sold nearly 700 simulators and training devices to airlines, aircraft manufacturers, training centers and defence forces globally. Nevertheless, despite being the market leader in hardware, CAE long ago realized that not every operator wanted (or could afford) to purchase its own simulator. The company saw an obvious need to diversify beyond merely producing simulators – however successfully – and began establishing training centers around the world to cater for such operators. CAE made a number of acquisitions and began establishing training organizations in joint-ventures with companies like Iberia (in Madrid), Alitalia (Rome), Singapore Airlines (Singapore), China Southern Airlines (Zhuhai, China), Aeroflot (Moscow) and Air Asia (Kuala Lumpur). These are just six of the 22 training centers that CAE now has scattered strategically around the globe. Each joint-venture is a symbiotic partnership that offers significant benefits to both partners. In the case of the various airlines, each receives the benefit of CAE’s experience in simulator technology and ability to provide the highest quality training available. Both CAE and the partner company benefit from the ability to attract customers from the respective regions in which the training centers are based. Heli Ops asked ECFT’s Senior Sales Executive, Muhammad Usman Mastan, why ECFT would be interested in establishing a helicopter simulator. Mastan explained that the decision was purely a business one. The (joint) company realized the growing need for an appropriate simulator for the rapidly growing helicopter market in the Middle East. So what was the reason for selecting the 412? Mastan explained that the company maintains a “census” of world aircraft fleets and constantly watches the order books of the world’s aircraft manufacturers (fixed-wing and helicopter) so that it can anticipate demand for simulators. There have been well over 400 Bell 412s produced, and a large number of them operate in the region. With simulator training now being strongly emphasized in the region, operators were all faced with having to send pilots to training centers across the world. It made perfect business sense then, for ECFT to follow the same model they had with their fixed-wing One of two rows of multimillion-dollar simulators that equip the Emirates-CAE facility. simulators, and establish a regional helicopter training facility in its Dubai training center – already ideally located at the business hub of the Middle East. ECFT realized how much money local operators would otherwise have to spend to send pilots elsewhere for training. It was obvious that a “local” simulator would be a popular addition to its Dubai facility; nevertheless, the decision was not made lightly. The simulator that the company has built and installed is around US$20M, and is among the most expensive single simulator in the facility. This is a little ironic as the aircraft type it replicates – the Bell 412 – is by far the least expensive type of aircraft being simulated! So why are helicopter simulators so expensive? For the same reason that helicopters are so expensive – the complexity of the helicopter! In addition to the normal six axes of simulator movement, the helicopter sim requires the addition of a vibration platform with its own three axes of movement. ➤ 41 T h e l e a d i n g l i g h t i n a v i a t i o n s e r v i c e s .

Where a conventional airliner simulator has 180-degree horizontal and 40-degree vertical visuals, the helicopter sim requires 220 degrees horizontal and 60 degrees vertical visuals plus the lower chin windows in order to properly depict the environment. The UAE requirement for helicopter simulators doesn’t specify level-D. Heli Ops asked Mastan why ECFT elected to install such an expensive simulator. “All of our simulators are level-D,” he said. “ECFT is committed to excellence in training and service, it is what makes us what we are that we only offer the best in terms of technology, facilities and instructors. There was never any question that it would have been anything but a level-D simulator.” Wouldn’t a level-C simulator have been cheaper for customers? “Not really,” says Mastan, “not considering what we offer our customers. Once the simulator is up and running, there is not a huge amount of difference in the long term in ongoing costs and we make sure we keep our cost to the customers highly competitive. The big difference is in the quality of the training experience offered by having the best possible simulator.” ECFT’s 412 simulator has only been approved since January and its full courses were only approved in March – although local approval was obtained, and its first local training was carried out in February. Since it has been fully approved, the simulator has been used every day and was already operating at around 40 percent of its potential capacity by July. Customers as of July included Gulf Helicopters, Saudi Aramco, CHC Australia and the Dubai Air Wing. ECFT is talking with numerous other customers who are interested in using the simulator for regular long-term training, and already there has been interest from well beyond the “local” (Gulf) area. The 412 simulator’s potential customers include pretty much everyone outside the US. Dubai’s location renders it “central” to most other places, including Europe, as well as the Middle East, Africa, Asia and Australia. As far as potential customers for the simulator are concerned, quite apart from the economic attraction of not having to fly staff half-way around the world, Dozens of well-equipped classrooms rooms like this are in constant use throughout the training centre. its location in Dubai is a particularly attractive side benefit, as anyone who has visited there will be aware. Many of ECFT’s customers (fixed-wing as well as helicopter) elect to spend additional time in Dubai when “sims” fall due, often bringing families with them and vacationing in the city. Realizing this, the ECFT team have eleven full-time customer service account executives, whose job it is to take care of all logistics for those attending the training center. Students at the training center all receive “welcome packs” upon arrival that detail, not only everything they need to know about their courses, but also everything they need to know about their stay in Dubai – including such things as available amenities, places and items of interest and lists of local restaurants. The ECFT staff will even make arrangements and bookings at local attractions for those that request them. Standard services for simulator customers include processing visas (if required), and arranging and providing limousine transport to and from the training center each day. The limousine transport is not a luxury, but rather, an important tool that benefits students and training center staff alike because it is essential that briefings and sim sessions run according to strict timetables. Simulators are always carefully scheduled to maximize their valuable time – exactly like real aircraft. It would be costly and disruptive for students to arrive late for training, so the limousine service ensures this does not occur. In addition to the limousine service, standard services include the availability of heavily discounted rates at a number of top quality hotels near the training center. ECFT’s bulk-purchasing discount allows the center to buy multiple roomnights at these hotels and make them available at up to 50 percent less than standard hotel rates in some cases. For pilots attending the simulators each day, a fully serviced lounge (including Internet) is available throughout the day for pilots to relax between sims or classroom sessions. This is in addition to a large cafeteria serving all manner of quality meals. Everything about the training center is intended to ensure that pilots are able to concentrate and focus solely on their training – which, after all, is what they are paying for. Every one of those other “details” that travellers would otherwise concern themselves with is taken care of. There is no doubt about the quality of the facilities. Classrooms, briefing rooms, dining facilities, lounge areas – everything is immaculate, roomy, and classy. But what of the simulator itself, and what of the instructors? HeliOps engaged the services of Phil Croucher to fly the 412 simulator and give an independent verdict. Phil is a highly experienced pilot with a great deal of instructing and training experience and is also the author of numerous helicopter manuals and training textbooks. Instrument-rated, and with a background of both military and civilian flying, he is currently flying Bell 212 helicopters in the Middle East and thus ideally qualified to give an independent opinion on ECFT’s simulator. ECFT provided its chief 412 instructor, 43 left: The nerve centre of the Bell-412 simulator where Klepper or the other instructors can call up any of 180 faults for students to deal with. right: In addition to classrooms, there are spacious and comfortable CBT and procedural training areas set aside. Robert “Bob” Klepper, to put Phil through his paces in the sim. Klepper did not take it easy on Phil, despite Phil’s lack of familiarity with the 412. (ECFT runs a highly detailed “differences” course for 212 operators wanting to make use of the 412 simulator). While Klepper allowed Phil to get airborne and make his way to downtown Dubai (it was easy to recognize all the landmarks, having spent a few days in the city), once over the city he proceeded to throw a few problems at him. Every one of the 180 faults that the simulator’s software contains derives from events that have actually occurred – somewhere. Phil was quick to notice the low oil pressure in one engine, and it was here that the value of a simulator became instantly clear. The simulator is not just about teaching a “rote-learning” drill for a specific circumstance, but more about instilling the right thinking in pilots to deal with emergencies appropriately. After Phil sensibly decided to return to the airfield, he also began contemplating an emergency landing, which is the kind of thinking Klepper looks for. When the second oil pressure light illuminated, Phil immediately made a “run-on” landing into the sand alongside Sheikh Zayed Road. So realistic was the situation, that the writer found himself frantically pulling harnesses tighter and clutching tight 44 upon seat arms as the 412 neared the ground. The solid impact with the ground felt extremely realistic – truly as if the heavy 412 had plopped into soft sand alongside the road and slid to a halt. In important ways, simulators can thus provide more “realistic” training than real helicopters, in that they allow emergencies to be handled to their conclusions, exactly as they would be in the real world. An engine failure is a perfect example. In the real world, few organizations practice autorotations to the ground. The risks to people and helicopters are too great. A B206 pilot, for example, will be aware that he or she will be making a “power-on” recovery and will therefore focus as much on avoiding a torque-spike as on the correct auto technique. In a simulator, it is a real failure – all the way to its conclusion, and it is up to the pilot to get it right if the conclusion isn’t to replicate a crash. It is human nature to revert to training in the event of real emergencies, and if “real” training doesn’t actually prepare pilots to handle emergencies, its value has to be questioned. In a simulator, pilots can begin to gain the necessary appreciation that emergencies don’t always occur over nicely level, welllit, “safe” airfields or large open spaces. A real emergency may well necessitate “breaking” a helicopter to manage the emergency properly and this is obviously impossible to reproduce outside a simulator. (Phil’s double engine-failure and subsequent forced ditching was another good example). There are a great many emergencies that can simply never be trained for in a real aircraft, but the simulator’s ability to allow pilots to learn exactly what the “real” thing feels like, and how to deal with it, may well be the difference between surviving an unusual emergency and becoming another statistic. After a series of emergencies and abnormal situations, Phil admitted to experiencing the genuine “wobbly knees” sensation so well known to pilots in real aircraft, and the sweat was certainly evident on his brow. Asked later for his opinions of the simulator, he was in no doubt. “This simulator is extremely accurate – very good. When I made the running landing into the sand, I could feel the drag on the skids exactly as I’d imagine and I could see the waves of sand blowing around the machine.” He then commented on the importance of complete reality if a simulator was to have real benefits. “There’s no point in having a “nearly accurate” simulator where an instructor needs to remind a pilot to ignore something because it wouldn’t be there, or wouldn’t do that in a real machine,” he said. “This really is a complete Bell 412 – right down to the smallest detail.” Klepper, who began his career as a helicopter crew chief in the US army, learned to fly helicopters with a cropdusting company. He has since spent much of his life in the air and now has around 19,000 hours – and still loves his flying as much as he ever did. His passion for training is refreshingly genuine. He is a big believer that simulator training is just another tool for instilling the right attitude in pilots – the attitude that encourages pilots to avoid putting themselves in situations that require significant piloting skill to subsequently recover from! He clearly appreciates the simulator for what it offers pilots. “The sim allows pilots to overcome the natural human tendency towards “disbelief” in a real emergency,” he says. “In a helicopter, there just isn’t time for that – by the time it has sunk in, it can be too late to do anything about it. If a pilot has seen it and done it in a sim, it is that much more likely he or she will react automatically – and correctly.” Klepper firmly believes in the need for strong CRM and feels this is also a strongpoint for simulator training because it trains a crew to become a cohesive unit – and a cohesive crew can minimize the effects of many malfunctions. He also believes that, in the interest of safety, it would be beneficial to have crewmembers who fly in a single-pilot aircraft, to attend training as well. ➤ “All I remember was someone saying, watch your step” Don’t let this happen to you...

He is clear that his goal is to do everything he possibly can to prepare pilots to keep themselves and their passengers alive if the worst ever happens. “If a pilot can’t learn from an exercise, there is no point in it, so we never set impossible tasks.” Increasingly, insurance companies are insisting on simulator training as a condition of covering helicopter operators.

These belts are checked consistently with every story & PHOTOS by Sarah Bowen walk-around, but the signs of cumulative wear or damage can sometimes be difficult to spot. Taking these belts for granted is not an option; it’s sobering to think that in effect, all that is between you and a power failure may be a strip of rubber! That said, complete malfunctions of belts are rare, and most wear-and-tear related problems are usually identified and resolved during maintenance. Belt systems vary between manufacturers but all rely on similar principles. It is important to know what can be done to prevent something from going wrong. Schweizer, Robinson and Enstrom machines each employ a rubber belt system to transfer drive from the engine to the main transmission. Robinson uses multiple v-belts, similar to those that drive the alternator on the average car. On the R22, the engine’s rotation is transmitted to the main gearbox via two drive belts carried on “sheaves” or pulley assemblies. Each belt effectively comprises two v-belts joined together; thus the pulley has four grooves. The belts transmit the drive to a similar pulley assembly mounted on the main gearbox/tail rotor drive shaft. The belts are designed to act independently and offer redundancy in the event of a single belt failing. Enstrom’s piston helicopters make use of a single serpentine belt that is 6.5 inches across and has approximately 35 ribs. It has a smooth non-driving surface and a multi-grooved drive surface. A jockey pulley, which sits between the engine pulley and the gearbox pulley, moves in and out to increase or decrease pressure on the drive belt, providing a “clutch” mechanism between engine and gearbox; this is manually activated by the pilot for initial rotor engagement. The system incorporates an automatic freewheeling clutch in case the engine should fail. Even the turbine-engined Enstrom 480 uses a rubber belt drive system; the main difference being that on this system the belt maintains tension at all times. The Schweizer 269C system is similar, except that it uses eight belts and has an electrically operated mechanism. Because the eight belts move independently, if one of the belts were to malfunction, the remaining belts would continue to transfer power to the main transmission and tail rotor. The v-belts on the 269 are exposed and not concealed behind a fairing; any grit or FOD entering the belt system is likely to fly out again rather than getting caught up in the pulleys. On the turbine Schweizer 333, a single poly v-belt replaces the eight single belts. This results in better mechanical efficiency; on the eight-belt system the v-belts all move at slightly different speeds, which means that some work harder than others, putting a higher strain on the top left: The complete Robinson R44 drive assembly consists of upper and lower sheaves, clutch actuator, lower bearing and four V-belts; twice the number of belts the R22 uses. top right: R44 lower bearing assembly showing the lower sheave and V-belts. These are normally protected by the aft cowling, which has been removed for maintenance. The R44 belt system design has proven exceptionally reliable. ABOVE: The poly V belt used on a S333 performs the same job as the eight individual belts on the 269, but tends to provide better mechanical efficiency due to the whole belt moving at the same speed. 50 drive system. This can be demonstrated by drawing a line across the belts before engine-start; the mark will almost certainly not line up once the engine has been shut down again. Harder work means more wear-and-tear and shorter belt life than the single poly v-belt, which provides more reliability and less need for maintenance. One major advantage of belt drive transmissions is a reduction in maintenance costs as there is no mechanical gearbox and no associated seals, oil, gears or casings to maintain. A belt drive is pretty much a “fit and forget” system that requires very little in the way of maintenance. A pre-flight inspection of the condition of the belts and sheaves offers an effective assessment as to the serviceability of the system; more complex mechanical systems give little visual clue of impending problems other than perhaps discoloured oil or a chip light. The belt drive allows for a very compact installation and is a much cheaper option when it comes to the initial design of the helicopter. Andrew Wilson, an engineer for UKbased Total Air Management Services, talked about the belt drive system on the Schweizer. “Our personal experience has been that the “poly-v” on the S333 – our fleet leader – is capable of lasting more than 1,600 flying hours. Other operators have had belts run to over 2,300 hours with no visual evidence to require replacement.” It is not unusual for an R22 or R44 to achieve its overhaul life on its original set of belts. Enstrom receives similar reports. The belt drive system is also a very effective way to isolate vibration from the dynamic components to the engine and vice versa, which improves the ride and extends component life. Although there have been few incidents resulting directly from belt failure, accident and incident reports have helped manufacturers improve their designs and procedures. One consistent factor that has been identified by manufacturers is the tendency for nearly all failures to occur in relatively new belts; those with less than 50 hours – most with less than 20 hours time-inservice. This is because new belts are soft and tend to grip the sides of the grooves, increasing their tendency to “climb” out of the sheave. Initiation is thought to be either a belt strand coming out of, or rolling over in a groove, leading to an overload condition that ends up tearing the belt apart. The most common causes have been associated with high gross weight power applications – occasionally exacerbated by turbulence, sheave alignment at installation or alignment shifts caused by initial belt wear-in, new belts that are fitted to worn or corroded sheaves, actuator tension out of specification, or excessive belt slack at initial engagement, allowing a belt strand to be outside either the forward or aft grooves when tensioned.

Assuming the engine had failed, he lowered the collective and entered autorotation. As he turned into wind he raised the collective to flare the aircraft, but the right skid touched the ground first and the helicopter rolled over. On examination of the wreckage, one of the transmission v-belts was found to be missing, and there was evidence of rubber deposits around the transmission compartment suggesting the belt had flailed after malfunctioning. The remaining belt was still intact and appeared undamaged, and there was no evidence of any other pre-impact failure. It emerged that the v-belts had been replaced just 12 hours prior to the accident, highlighting the vulnerability of low-time belts to failure as a result of stretching after installation. Stretching can cause the belts to partially ride up out of the pulley grooves during clutch engagement. This is the reason for the five-second limitation for the blades to start turning during start-up. Although the clutch actuator should always maintain the correct belt tension when engaged, an abnormally long time interval between selection and rotor movement indicates that the actuator is travelling further before the correct tension value is reached, and this is when damage can be caused. In 1998, Robinson Helicopters issued a safety notice recommending that on R22s with newly installed v-belts, during shutdown the clutch should not be disengaged until the belts have had a chance to stretch and properly bed in. This procedure is said to relieve unnecessary torsional stresses placed on the drive train by new belts. Robinson belts are manufactured and fitted as matched pairs, and as part of the manufacturing process, all belts are also “broken in” for five hours at full RPM and tension before shipment, making them far more tolerant. They are maintained “on-condition” and do not have a finite service life. According to Frank Robinson, the system is relatively maintenance-free as far as the belts are concerned. He said it works very well most of the time, and on the R44 it has been practically troublefree. The R22 has had some problems with the v-belts in recent years, primarily because the aircraft was originally designed for an engine of 108 hp, but this has since progressively increased in power to 150 hp, then 160 hp, and now 180 hp. 51 support the v-belt drives; we try to stay on top of improvements to make sure everything continues to perform reliably.” Enstrom Equipment ABOVE: Enstrom piston helicopters use a single serpentine belt controlled by a lever and cable that latches the mechanism over center to prevent accidental belt clutch release. ABOVE RIGHT: S333 upper pulley and freewheel unit, lower pulley with oil cooler fan duct, “H” frame, idler tensioning pulley, belt guide and upper tensioner attachment. “The biggest problem is that the R22 has just grown and grown, but the capacity of that v-belt design cannot be increased simply because of space and geometry limitations in the helicopter. When we designed the R44 we started with a clean sheet of paper and were able to double the number of v-belts; this has proved to be exceptionally reliable.” Undoubtedly one of the most serious – yet avoidable – causes of belt failure is a disregard of the limitations set out in the pilot’s operating handbook. “We have always been dependent on pilots limiting manifold pressure according to the tables given in the manual so that they never pull more than 131 hp during take-off and 124 hp max-continuous,” Frank Robinson explains. “The only thing preventing them from pulling more power is their own restraint and skill as pilots. We have had a number of cases – probably more down in New Zealand and Australia than anywhere else – where pilots have ignored the published limitations and just pulled whatever they want, thinking the helicopter could take it.” Robinson said this had led to failures of some v-belts as well as other parts of the systems on the R22. It is frustrating for Robinson that a small percentage of pilots refuse 52 to follow the rules and limit the power they use. Unfortunately, as Robinson points out, the damage of fatigue failure is cumulative and one pilot’s actions can affect someone who flies the helicopter later on – with potentially disastrous consequences! “If you want to live to a ripe old age, you need to fly safely and stick to published limitations!” The R22 system is very light, and when flown within limits, works very well. “The great thing about this system,” says Robinson, “where we raise and lower the upper sheave or pulley to engage or disengage the belts – is that it’s completely automatic; when you engage the clutch it raises that upper sheave, tensioning the V-belts until they reach a particular load, then it shuts off. If the tension load falls below a certain value in flight, it automatically turns itself back on and re-tensions the belts. This has allowed a greater safety margin in the belts themselves because we don’t have to design for slack belts; we can depend on the unit maintaining the tension.” Robinson also noted that the manufacturing process has improved. “Originally we machined the castings. We started out coating the sheaves with hard anodides, but as time went on – particularly with applications like cattle herding in Australia – it became clear that this just wasn’t good enough. We then switched over to sprayed-steel coatings and subsequently stainless steel to improve the wear characteristics. Nowadays, instead of making the sheaves out of castings, we actually machine them out of bar stock using CNC machines. “We’ve also updated the bearings that On Enstrom 280 belt systems, normal maintenance consists of inspecting the large roller and the actuation straps carefully at the 100-hour inspection; the top of the clutch capsule should also be inspected as the bushing is subject to wear. Enstrom has used this design since the 1960s, and it has proved reliable. Bayard Dupont, Director of Product Support at Enstrom Helicopters said that he had never heard of a belt failure. “There is no risk of one belt coming loose and causing other belts to come off. These belts typically last 1,500 hours or 15 years and can be run until pieces the size of a US 25 cent coin are delaminating from the insides.” The only time-limited parts are two bearings in the large roller, which need to be changed at 600 hours. According to Enstrom’s service information letter 0074, belt inspection – carried out as part of every routine preflight check – should include observing any damage, unusual wear or signs of fatigue and separation of components. All belt surfaces should be carefully examined. Firstly, the back of the belt should be examined for cuts, damage or blisters, which may indicate separation of the fabric plies; the belt should be removed if there is any damage that appears to penetrate the fabric cover. A small crack in the back of the belt at the fabric splice is not significant, however the belt should be removed if there is loosening or peeling of the fabric in the splice areas. Secondly, the edge of the belt should be examined for signs of wear; this does not affect the belt directly but would indicate that there is a tracking or interference problem. Fraying of the edge cord is not significant; however, if an entire cord is beginning to emerge from the belt, or if there is any sign of separation or rubber from the cord it should be removed. Finally, it is fairly common to have horizontal cracks across the belt; they are quite acceptable provided the chording cannot be seen when the belt is flexed back and the crack opened up. Loss of small pieces of rib section may accompany rib cracking; generally speaking this is a random occurrence, but the belt should be replaced if three or more adjacent ribs are lost for a length of two inches or more.

Mediocrity will no longer be accepted…and failure is not an option. Late deliveries will no longer be the norm; spare parts genuine and easy to find. Through vertical integration and acquisition of manufacturing facilities worldwide, we are taking responsibility for our supply chain. Our company and its supply chain are being fortified with the same intensity and commitment with which we build our helicopters…we are taking responsibility for every aspect of our operations so that we can be responsive and responsible to our customers. Winston Churchill once said, “The price of greatness is responsibility.” Turning that around, only through responsibility, can greatness be achieved. We offer an exceptional product. NOTar® technology makes our helicopters among the safest and most quiet in the sky. Our new safety features are meant to place MD among the industry leaders – wire cutters, terrain avoidance systems, HUMS cockpit video and audio recorders with our training programs, places safety at the top of the MD priority list. Our mission is to bring evolution and innovation to the world and to deliver it on time – to keep aircraft in the air and operators safe of flight. heritageaviationltd.com We’re making everything. Except excuses. mdhelicopters.com Dupont said that one of the nice things about Enstrom’s belt system is that the belt can be disengaged on the ground, allowing the blades to stop so that rotor tracking and similar maintenance can be performed with the engine running. He also noted that belts can be quite noisy during engagement, “but believe it or not, this can usually be controlled by applying talcum powder to the inside of the belt.” Dennis Kenyon, ex-Royal Air Force fast jet and bomber pilot, and now instructor and examiner in the UK, has been flying civilian helicopters, mainly the Enstrom, since 1970. Kenyon, who has also won awards flying the Enstrom as a helicopter display pilot, confirmed Dupont’s high regard for the belt system. “The Enstrom system is very dependable. In over 30 years flying this helicopter I have not experienced a belt failure, nor have I heard of a single occurrence.” Schweizer System When the Schweizer 269C engine is started, the eight belts are not tensioned and are free to slip, thus ensuring that the engine is not connected to the drive and not under load when started. After starting, the engine is accelerated to 1,500 RPM and when the belt-tensioning switch is set to “engage” the v-belts are tensioned. When the engine RPM drop by 100 RPM, the switch is moved to “hold” until the engine again reaches 1,500 RPM. This procedure is repeated until the needles on the RPM-gauge are superimposed and speed synchronization is achieved. At this stage there is no belt slip and the belt-tensioning switch is left engaged. The electrically operated linear actuator transmits tension via a clutch cable assembly to an idler pulley acting on the v-belts. When the belttensioning switch on the instrument panel is activated, the linear actuator draws in and tensions the clutch cable, which in turn draws in the idler pulley and tensions the V-belts. This type of belt system appears to be extremely reliable and statistics reveal very few incidents involving Schweizer belts; any problems seemed to have been with the clutch cable rather than the belts themselves. System efficiency It has to be more than a coincidence that Robinson, Schweizer and Enstrom have all adopted this system, which begs the question; if belt drive transmissions are so good then why don’t all helicopters have them? Efficiency, is the simple answer. The energy absorbed by a belt from constantly forcing it to bend around a pulley and then straighten is known as “transmission loss” and is acceptable in small helicopters. However, powerplants in large helicopters are more robust and would require larger belt drives to transmit power; with this would come larger transmission losses. There is a point where the efficiency-cost graphs cross over and the belt drive is no longer the viable and cost effective option it is with the lower-powered engine. Clearly these rubber belts play a significant role in the smooth running of the helicopter, but they must be respected. The vast improvements that manufacturers have implemented have contributed to a reduction in accidents and incidents involving belt failure. If pilots and engineers perform regular and thorough inspections of belt condition, and ensure that they adhere to published power limitations, then the possibility of belt failure can be minimized. n BREEZE-EASTERN HS-20200 HS-29700 HS-10300 HS-29900 AGUSTA BELL 212/412 AGUSTA A109K2 AGUSTAWESTLAND EH-101 SIKORSKY UH-60Q AGUSTA BELL AB139 EUROCOPTER AS-350B3 EUROCOPTER AS365(HH65) AGUSTAWESTLAND EH101 HELICOPTER RESCUE HOISTS MDHI MD902 700 Liberty Avenue, Union NJ 07083, USA Telephone: (908)686-4000 Fax: (908)686-9292 Web Site: www.breeze-eastern.com We Fly We Maintain The Powerful Difference We proudly use our experience and facilities to support the Warfighters of Oregon and the nation.

One subject prone to such misinformation is performance. HO1 HO2 HO3 HO4 Many accidents are performancerelated, particularly among those that occur during takeoff and landing. This is especially true when a helicopter is heavy, and/or operating in high densityaltitudes. In trying to get a large, heavy object (helicopter) into or out of a relatively small place, the whole point of performance calculations is to ensure that the space required for taking off and landing is not more than the space available, taking into account an engine power loss at the most critical moment. The idea is to keep a helicopter’s mass within limits during all phases of flight, because the lower the weight of the machine, the better it will fly in the event of reduced power. The performance charts in flight manuals tend to be optimistic and are based on new machines flown by skilled pilots, so although the graphs provide a maximum weight for the conditions, it is wise to allow an extra margin – remember, the maximum weight is a limit and not a target! For performance purposes, helicopters are certified in one of three classes (1, 2 or 3). These are different from airworthiness groups or categories, which only dictate a helicopter’s basic ability to fly with an engine out and withstand things like forced landings. In other words, the terms Category-A and Category-B (as opposed to Class 1 or 2) are for certification or airworthiness purposes. The performance class, which is an extra layer of operational 58 paperwork, determines the necessary clearance that must be able to be maintained during takeoff and landing. People often refer to Category-A performance when they mean Class-1 performance. Here are some selected definitions related to performance: Clearway. An area at the end of the Takeoff Distance Available (TODA) that is unsuitable to run on, but which is clear of obstacles, so you can fly over it. Although it is not ground-based, you can include it in your calculations, because you should be staggering into the air towards your screen height just before you reach it. Although the graphs provide a maximum weight for the conditions, it is wise to allow an extra margin – remember, the maximum weight is a limit and not a target! Defined Point After Takeoff (DPATO). In Class 2 operations, the point – during takeoff and initial climb – before which, the helicopter’s ability to continue the flight safely, with the critical power unit inoperative, is not assured and a forced landing may be required. Defined Point Before Landing (DPBL). In Class 2 operations, the point – during approach and landing – after which, the helicopter’s ability to continue the flight safely, with the critical power unit inoperative, is not assured and a forced landing may be required. Distance DR. The horizontal distance the helicopter has travelled from the end of the TODA; used for adding “fudge factors” to obstacle clearances (for example, 0.01 of DR is added when IFR). Drift Down. The amount of height that is lost between the time an engine fails and when a pilot can fly away safely under control. Hostile Environment. Where a safe forced landing cannot be made because the surface is inadequate, the occupants of a helicopter cannot be adequately protected from the elements, SAR response or capability is not consistent with anticipated exposure, or there is an unacceptable risk of endangering people or property on the ground. The open sea north of 45°N and south of 45°S, as designated by the authority of the state concerned, and congested areas without adequate safe forced landing areas are hostile environments. Non-Hostile Environment. An environment where a safe forced landing can be accomplished, occupants can be protected from elements and SAR response or capability is consistent with anticipated exposure. Congested areas with adequate safe forced landing areas are non-hostile. Safe Forced Landing. An unavoidable landing or ditching where there is a reasonable expectancy that there will be no injuries to persons in the aircraft or on the surface. Thus, a congested area without a safe forced landing area does not meet the definition, since third parties may be injured. Such areas are hostile areas, as are forests, open seas, and mountains, except that states often turn a blind eye to mountains because there are hardly any helicopters that can maintain level flight over a high range. The “safe forced landing” is an ICAO concept that has been adopted in JAR OPS. Takeoff Decision Point (TDP). The last point from which a takeoff may be safely rejected, or flight continued after a power-unit failure has been recognised. It is the only point at which there is a choice of action – before it, takeoff is rejected. After it, takeoff is continued. VTOSS. Takeoff Safety Speed in a Class 1 helicopter (equivalent to V2 in an aeroplane). It was developed because it is below Vy, and is repeatable. It gives a better angle of climb than rate of climb, because you’re more interested in clearing ground in a short distance than in how quickly you’re going up. VY. Best rate of climb, or the most height in the shortest time. It corresponds with the greatest difference between available power and power required. Airworthiness Categories 4 Category A This provides for multi-engine helicopters with engine and system isolation, working under a critical engine failure concept. Category-A allows continued flight because of redundancy (another engine) or a design process that limits the probability of failure. Engine isolation means that one engine failure is unlikely to lead to a second, and that fire in an engine compartment can be detected and contained or extinguished. Category-A also specifies, for each profile (see below), the flight manual data to calculate required areas for landing HO 5 (or re-landing) if an engine fails, together with OEI obstacle clearance. More comprehensive flight and navigation equipment is also listed. Profiles A takeoff or landing profile is a set of manoeuvres designed to provide continued safe flight or a controlled landing after an engine fails. Singleengine helicopters have profiles as well, which are designed to avoid the height/ velocity curve by about 10 ft and 5 knts. The usual JAR/FAR profile includes a first segment climb performance of 100 ft/min at VTOSS from the end of the takeoff distance required to 200 ft, a level acceleration segment from VTOSS up to VY (which may be combined with the first segment climb), and second segment climb performance of 150 ft/ min at VY at 1,000 ft above the takeoff surface. HO 1 The weight & temperature graph in the flight manual (otherwise known as the WAT curve) will provide a suitable takeoff or landing mass, but it assumes a standard lapse rate, so be careful if there is a temperature inversion. In practice, with both engines performing as they should, you would accelerate as quickly as possible through TDP and climb away as normal (it’s better for the passengers’ coffee, but you must still take account of the height/velocity curve in case you suddenly become a single-engine helicopter). Only if an engine fails (especially under IFR, where you can’t see anything) would you hit VTOSS, or takeoff safety speed (the equivalent to V2 in an aeroplane), for the best angle of climb, then adopt VY at the prescribed height, for the best rate of climb. In such a case, you must fly the profile accurately to ensure obstacle clearance! 4 Category B This covers single-engine helicopters, or multi-engine machines that do not fully meet Category-A requirements. They are not guaranteed to stay airborne if an engine fails and a forced landing is assumed. Performance Classes The performance class determines the outcome after an engine fails. You must not be heavier than the performance regulations you choose to work under. The performance data in the flight manual – supplemented as necessary – must be used to determine compliance. 4 Class 1 This helicopter class requires no forced landing provisions if the critical power unit fails – the machine can either land within the rejected takeoff distance or continue (safely) to a suitable landing area, depending on when the failure occurs (that is, before or after TDP), clearing all obstacles vertically by 35 ft with an engine out (plus a percentage of DR when IFR). HO 2 The part of the takeoff up to and including TDP must be completed within sight of the surface, so a rejected takeoff can be carried out visually if needed. Thus, there should be no possibility of an accident if an engine fails at any stage of a flight. There are three variations on the Class-1 takeoff theme that comply with Category-A: Clear Area As if taking off from a runway, with nothing in the way. It satisfies legal minima as long as you can maintain 100 ft/min at 200 feet with one engine out, and 150 ft/min at 1,000 ft. A fixed 59 HO 7 The Defined Point After Take Off (DPATO) defines the point from which OEI obstacle clearance can be assured. HO 8 HO6 TDP is normally used because there is nothing to restrict your ground run or flight path. the ground) the same applies, but you have an extra space in which to drop down and gather some speed: HO 3 Restricted Area With nearby obstacles that must be cleared by 35 ft, and a surface on which a reject can be carried out. A steep or vertical climb is required before proceeding forward over the obstacles. The TDP can be varied to give an improved clearance (or clear a higher obstacle), but as its height increases, it is more difficult to land back in the reject area. HO 6 (Note: Taking the doors off might invalidate the data for performance Class 1)! HO 4 Helipad The rejected takeoff area is the helipad itself, so you must be able to keep it in sight to re-land if the engine fails before TDP. For non-elevated heliports (i.e. at ground level), the takeoff to TDP is a rearwards climb, if there are no obstacles behind. If there are (for example, on an oil rig), TDP will normally be at or below 30 ft. HO 5 For elevated heliports and helidecks (e.g. oil rigs, or anything above 3 m from 60 Landing This is a PC1/Category-A Landing procedure: HO 7 There are two requirements – all obstacles must be cleared in the approach to land, and the helicopter must be able to stop in the distance available. 4 Class 2 Here, there is no ability to climb away if an engine fails before DPATO (or after DPBL when landing). If an engine fails in the early stages of takeoff or late stages of landing, you will be faced with a forced landing. However, once past DPATO, or up to DPBL, the same OEI performance as Class 1 is available. If surface conditions were acceptable, a safe forced landing would be possible. However, if not, there is exposure – measured in seconds – during which there is no guarantee of a flyaway or safe forced landing. The maximum permitted exposure time is a statistically derived figure, during which the probability of an engine failure can be discounted. Operations in Class-2 do not specify a rejected takeoff (although occupants and third parties must remain uninjured) when the failure occurs early in the takeoff or late in the landing, so a forced landing may be required, under conditions that allow it, in terms of weather, light and terrain. This is because Class-2 assumes that all engines are operating until the point at which you should be able to sustain a Performance 1 climb. Thus, you have two sets of obstacle clearance limits, since Performance Class-2 is a mixture of Class-3 (takeoff and landing) and Class-1 (climb, cruise, descent). HO 8 The Defined Point After Take Off (DPATO) defines the point from which OEI obstacle clearance can be assured. At the moment, it is quite difficult to calculate, as not all flight manuals provide allengines-operating (AEO) data. Until you reach DPATO, you must clear all obstacles by 35 ft AEO. You are assumed to be VMC until ➤ DPATO, so IMC is not allowed if an engine fails, as the necessary climb gradients will not have been established. 4 CLass 3 Multi-engine types operated in this class may have to make a forced landing, while single-engine types will. If you are flying over water in a twin-engine helicopter and don’t have enough power to get back to shore if an engine fails, Class 3 limitations and conditions must be observed. Commercial air transport operations must be conducted in sight of the surface, by day, with a minimum ceiling and visibility above the local surface. In the cruise, you must be able to maintain the minimum flight altitude, and the mass must always allow a hover IGE. Class-3 is not allowed in IMC or at night. Procedures The performance group to which you belong depends on certification, max all-up weight and the number of passengers carried. However, it may be more commercially acceptable to operate at a lesser performance level if it allows the carriage of greater payload, which makes more money – all that is needed is a longer takeoff run or fewer obstacles. In other words, the performance conditions under which you operate determine how heavy your aircraft can be and, as a result, your payload. Over a whole trip, the weight could be dictated by: u Maximum weight u WAT limits u Space available uObstacles u The route u Hovering OGE (you may have to accelerate OGE off a rig or small site) There are some principles with performance calculations that remain constant: u Mass must not exceed that specified in the flight manual for the conditions. u You must maintain a minimum climb gradient to keep you above the slope of the obstacle clearance plane. If an obstacle protrudes into the obstruction clearance plane, it follows that a higher climb gradient will be required and this will be specified on the approach or departure plate. I hope this brief summary of some important aspects of helicopter performance helps. In every aspect of flying, the right knowledge is essential to safety, but knowledge of performance is perhaps the most safety-critical knowledge a pilot must possess.” n Note: Flying an instrument departure u You can only plan to use 50% of any reported headwind component, and must use 150% of any tailwind. u You must account for weight, altitude and temperature (WAT) for the destination as well. All may restrict your takeoff weight. u Distances required must not be more than distances available. using a published procedure does not guarantee obstacle clearance if an engine fails. Therefore, you must limit the weight of your aircraft in order to clear all obstacles during takeoff in the event of a failure of the most critical engine. However, there may be procedures that allow obstacles to be avoided laterally by making a turn (or a series of turns) onto specific headings or tracks. 10681_HeliAd_HR_105x148.qxd 1/7/05 2:59 pm Page 1 CARGO HOOK EQUIPMENT Helicopter Load & Lifting Solutions • Cargo Hook Suspension Systems • TALON™ Belly Cargo Hooks • TALON™ Long Line Cargo Hooks The Ultimate Helicopter Market Information System The world’s most powerful market information source for civil and military turbine powered helicopters.

You rely on us. t h e l as t w o r d I make my living leading groups of aerospace folks to do difficult things – like taking truckloads of materials and components into a factory, and flying them over the fence at the other end by nick lappos as completed helicopters. Miracles like this do not happen by magic; they are performed by teams of people who are experts at what they do. I once told a reporter that when I was eight years old I had fun making airplanes, and that things are no different now except that I have hundreds of expert friends to help! Recently two high profile For this reason, I find strikes within our aerospace industry giants industry particularly disappointing. I see a company as a team. The whole have experienced long and concept is somehow wrapped into the word “company” itself, from the Latin, unsettling strikes. This is literally meaning those who break bread together. When a company splits on hard to comprehend in an itself and walks out, or locks out its other industry that relies so heavily half, something has failed. Failure is an option and nothing speaks to failure quite on teamwork... so much as when people bet their jobs on an economic power play, a game of corporate chicken where one side bets their mortgage payments that the other side will crash into economic chaos sooner. Just as when adolescents play “chicken” in speeding cars, the game is not for the faint-hearted, and the outcome can be disastrous. The helicopter industry is much like a delicate flower that grows A company is a team on rocky soil, perched in an in which, each day, environmental niche where it is mechanics and inspectors, mostly a struggle to keep on living passenger handlers and long enough to seed the next ops specialists, pilots and generation. In an industry flight-line workers all play marked by fierce competition, low their parts in an opera of margins and slim market segments, delicate timing. only the fittest survive. A company is a team in which, each day, mechanics and inspectors, passenger handlers and ops specialists, pilots and flight-line workers all play their parts in an opera of delicate timing. One mistake can be disastrous to the occupants of the machine and the confidence of the customer. What does it take to get a person to dare his boss to When Industry Strikes 64 fire him? What does it take for a manager to set his jaw so firmly and say “no” to requests from the workers he relies on? When does the “can do!” that lubricates every action of the team turn into “no way!” on both sides? Attitudes harden in strange ways. I am amazed when former military officer-pilots – normally as politically conservative as Genghis Kahn’s division staff – start talking like Jimmy Hoffa’s PR agents. And I am equally amazed when company executives who make a living satisfying customer requirements call them to say, “No can do.” Two bastions of the helicopter industry – Sikorsky and PHI – have both experienced long and unsettling strikes. The PHI strike is still unsettled as of this writing. In both cases customers suffered, as did employee morale, stockholder value and community acceptance. It seems that a strike, just like a war, is ultimately a failure of diplomacy, a failure of communication, and a failure of teamwork in which everybody loses. I have flown thousands of hours performing missions planned by other people, in machines that had been built and maintained by other people in which I trusted to do their jobs well. I trusted them with my life, frankly. I guess that means that I know what good teamwork is like, and I know that our industry, perhaps more than most, relies on good teamwork. Standing on a rain-swept seawall years ago, as I leant against a rusty railing at the sea’s edge, my eyes stinging from the spray, I watched a line of helicopters flog against a stormy sky into the Oil Patch. Big, powerful, rusty workboats in the harbor below were firmly moored, afraid to brave the conditions at sea. Oblivious to the same conditions, the flimsy helicopters crawled against that fierce headwind, a thousand feet above whitecaps and spray, to make the schedule work, to keep the oil pumping, to carry people and supplies to where they were needed. That experience is one of my fondest memories, because I could see in my mind’s eye all the interlocking promises that had to be kept to make that scene unfold – all the people in factories, gas trucks, pilots’ lounges, operations shacks, executive offices, safety conferences, even at keyboards, contributing to that wonderful scenario. Just the same way, I can see the failures whenever a strike occurs. n
