1. SCOPE AND OBJECTIVES OF THE PLAN
The Heathrow Snow Plan Airside, (HSPA) endorsed by the Heathrow Airport Holdings Limited Exec, describes the
structure of the Airside response of Heathrow Airport Limited (HAL) to a snow event. The aim of the HSPA is to
minimise the disruption of any snow event on the normal operation of LHR and to assist the continued and safe
operation of the airfield, even if conditions require this to be at a reduced capacity.
The HSPA aims to optimise the resources to be deployed, considering the operational impact and the expected level of
response of LHR to a snow event including equipment, people, materials and consumables.
The HSPA will be reviewed annually prior to each winter season. It will also be reviewed on an ‘as needed’ basis
during the year.
2. REGULATORY REQUIREMENTS
This document is published in accordance with the requirements of UK AIP AD 1.2.2 Snow Plan and CAP 168
“Licensing of Aerodromes” - Chapter 3, 11.2.5. Snow Plans, Appendix 3G “Care of Pavements during Winter
Conditions – Improving Surface Friction by Removal of Contaminants”. It also meets the requirement of “ Part D2 of
the CAA’s Notice Granting Heathrow Airport a Licence for the Economic Regulation from April 2014” All snow
clearance procedures will comply with CAP 168 and the UK AIP AD 1.2.2 Snow Plan procedures
This HSPA supersedes all previous Airside Snow Clearance Orders and plans and is effective from 1st November 2015
to 30th April 2016 and will be reviewed and potentially revised each year. The HSPA is issued with the agreement of
National Air Traffic Services (NATS) and following consultation with air operators.
Any enquiries concerning this Plan should be addressed to the Aerodrome Licence Holder, Derek Provan, telephone
0208 745 5366.
3. TRAINING
All personnel activated to facilitate the HSPA, both HAL and Contractors, should receive the necessary training to
meet their role. Training records will be held by the HAL Airside Training and Assurance and the relevant contractors.

4.2.
Airside Roles and responsibilities – Principal personnel
It is imperative that all stakeholders and internal staff link, at the appropriate level, into this command and
communications structure below (Figure 4.2).
Figure 4.2. Airside Snow Response Teams - Organisational Structure
The Winter Operations Team coordinates all aspects of Airside’s planning and response to Airside Winter Resilience.
The Airside Strategic Cell is the gateway to Airside for Airlines, 3rd parties and other Business Units. The ASC is
commanded by the Aircraft Flow Manager (AFM) and based in the Airside Room in APOC. The Airside Strategic Cell
will work in liaison with the Airport Operations Manager (AOM) at Bronze level, providing Airside expertise and
situational awareness as required by the APOC.
When a snow event is forecast, the ASC will be activated and the duty Aircraft Flow Manager (AFM) will work
closely with the following Airside subject-matter experts:
•
•
•
A Flight Performance Advisor, who will manage the night flights and early morning dispensations, ad-hoc
slots and external communications with DfT, CAA and FCO.
An Information Guardian who will collect, record and report all flight performance data and early warning
indicators in order to create the end of event report and provide context on de-icing performance and
coordinate the aircraft de-icing through the remote de-icing pads.
A Stand Allocation Unit Central Support who will provide support to the cell and the SAU Senior
Operations Controllers regarding snow dumps stands and contingency parking. The SAU Central Support will
provide the Information Guardian with Stands required information.
Page 7 of 25
The Airside Tactical Teams are managed by SNOCOs.
•
SNOCO 1 will tactically coordinate the runways and taxiways clearance.
•
SNOCO 3 will support SNOCO 1 running the Snow Base and allocating the runway and taxiway teams’
vehicles and manpower. In addition, SNOCO 3 controls the de-icing media for the whole operation.
•
SNOCO 2 will tactically coordinate the stands clearance, the airside roads and tunnels clearance, the snow
dumps and support teams. SNOCO 2 will be supported by a Tactical Log Keeper and Resources
Coordinator.
•
Under the management of SNOCO 2, the Terminal Coordinators will provide the Airside expertise to their
relevant terminals; the Airside Roads and Tunnels Coordinator coordinates the clearance of airside roads
and tunnels and the Vehicle Support Coordinator acts as the on-the-ground liaison and point of contact
for the vehicle maintenance external contractor.
•
Each Terminal Coordinator will be supported by a number of Stand Supervisors, Blades Teams Leaders
and Snow Escorts, who supervise the Stands Teams on the ramp, manage the Blades Teams and support
the clearance tasks by leading the snow teams on the airfield and ensuring a safe operation respectively.

4.3.
Aerodrome state and conditions of movement
DISSEMINATION OF INFORMATION
Internally, information on the current state of progress of snow clearance and on the conditions of the movement
areas (pavement conditions) will be available from the Terminal Coordinators and the Airside Strategic Cell in APOC.
Externally, information on current surface conditions at LHR will be disseminated by:
•
•
SNOWTAM: This describes the contaminant category, depth, location and information provided to the
NATs supervisor by the AfDM this is them sent by NATs.
NOTAM: Information passed by the AfDM or the AFM on their behalf.
Information on the runway surfaces conditions and operational availability will be gathered by the Airside Safety
Department (ASD) during activations. Runway friction measurements should not be attempted on a contaminated
runway. Runway condition assessments on all runways should be continuous during snowfall. The results of the
condition assessment should be reported by SNOCO 1 to the AFM and external stakeholders on a SNOWTAM in
accordance with the Aerodrome state and condition.
RUNWAY STATE ASSESSMENT
Regardless of air traffic movements, the assessment should cover the promulgated runway length. Account should be
taken of the cleared width of the runway in the case of contamination. The assessed area should be divided up into
equal thirds and reported as Touch Down, Mid-Point and Stop End.
Readings should be taken at approximately 300m intervals between 5 and 10 m on each side of the centreline,
avoiding the effects of rutting. Information is to be given in millimetres representing the mean of readings obtained
for each third of the total runway length.
THE NATURE OF SURFACE COVERING
•
Dry Snow: Snow that can be blown if loose, or that will not stick together to form a snowball using gloved
hands.
•
Wet Snow: Snow that contains enough water content to be able to make a well-compacted, solid snowball, but
water will not squeeze out.
•
Slush: Snow that is so water saturated that water will drain from it when a handful is picked up. Slush will
splatter if stepped on forcefully.
•
Compacted Snow: Snow that has been compressed into a solid mass such that the airplane tyres, at operating
pressures and loadings, will run on the surface without significant further compaction or rutting of the surface.
Compacted snow may include a mixture of snow and embedded ice; if it is more ice than compacted snow, then
it should be reported as either ice or wet ice, as applicable. A layer of compacted snow over ice should be
reported as compacted snow.
•
Water: Water in a liquid state.
•
Frost: Frost consists of ice crystals formed from airborne moisture that condenses on a surface whose
temperature is below freezing. Frost differs from ice in that the frost crystals grow independently and therefore
have a more granular texture.
•
Rime: Deposit of ice generally formed by the freezing of super cooled fog or cloud droplets on objects whose
surface temperature is below or slightly above 0 Degrees C.
•
Ice: Frozen water.
•
Wet Ice: Ice with a layer of water on top of it or ice that is melting.

5. COMMUNICATIONS
5.1.
Information management and coordination
The HSPA communication plan will link into the existing airport telephone and safety radio system. Airside’s response
to a snow event will be managed through the airside management radio system on the Channel 6 (Snow Channel for
Manoeuvring Area Teams) and Group 962 (for Stands, Airside Roads and Snow Dumps Teams). These radio systems
1
will become active on the activation of the snow teams and will be utilised by HAL Airside Teams .
Information is designed to flow up and down the HAL organisational structure, as set out on Chapter 4.2. Ultimately,
all decisions should pass through the HAL organisational structure until it reaches a level or individual that has the
relevant authority.
-
The Terminal Coordinators are responsible for managing communications throughout the Airside Team and to Third
2
parties . It is imperative that all stakeholders (external and internal) link, at the appropriate level, into the command
and communications structure. Circumventing this structure could cause confusion and inhibit HAL’s efficient
reaction to a snow event.

Conference calls
INTERNAL CONFERENCE CALLS
To facilitate the flow of information and situation awareness, conference calls will be held between the Airside
Strategic Cell and the Airside Tactical Team. The conference call schedule will be promulgated at the start of each
event and can be adjusted by the AFM, SNOCO 1 or SNOCO 2 to meet operational requirements.
At Snowfall T-4 hrs, a conference call should be held between the Airside Strategic Cell and the Airside Tactical
Team (SNOCOs and Terminal Coordinators). This call should not follow a prescriptive format but should include at
minimum weather and Terminal updates.
The Information Guardian, SAU Central Support and Night Flight Manager will start assessing the potential impact of
the snowfall to runway occupancy, stand availability and delay, night flights and cancellations against the schedule.
At Snowfall T-3 hrs, a more detailed conference call should be held between the ASC and ATT, where SNOCO 1 and
SNOCO 2 should provide the ASC with an update on their ability to deliver the full HSPA.

6. HEATHROW SNOW PLAN AIRSIDE OVERVIEW
In order to expedite anti-icing, de-icing and snow clearance activities, the Airside Strategic Cell and the Airside Tactical
Team will coordinate and direct the simultaneous clearance of runways, taxiways, stands and airside roads. Clearance
priorities should follow the basic criteria set-out within this plan; nevertheless, conditions on the day necessitate
amendments that will be implemented by the Airside Tactical Team, in consultation with the Airside Strategic Cell and
LHR’s stakeholders, as appropriate. An overview of each area of the plan is below.
6.1.
Snow Plan and MET Activation
In addition to the BAU team, on-call HAL personnel and contractors are activated to recover the airport during a snow
event.
Activation details are at Appendix 1.
6.2.
Anti-Icing Pre-treatment
Business-As-Usual. Pro-active anti-icing of all operating surfaces may occur at any time throughout the winter
period to counter hoar-frost and ice and may not necessarily be linked to the forecast of snow. In these circumstances,
the anti-icing treatment of operating surfaces will be carried out within BAU resources.
Pre Snow Event:
•
Runways/Taxiways. Up to five (5) anti-icing teams will be deployed to pre-treat the runways and taxiways
along dedicated routes.
•
Airside Roads. Similarly, airside roads anti-icing pre-treatment will be along pre-defined snow routes.
Additional anti-icing treatment will be laid on the approach ramps to the airside road tunnels.
•
Emergency Access Points. Rendezvous points will be pre-treated to ensure safe access and egress points
for the emergency services.
•
Aircraft Stands. On activation by the AFM in liaison with the AfDM, the Stand Allocation Unit will
coordinate the pre-treatment of all aircraft stands using up to three (3) dedicated de-icing vehicles. The
operation will begin no less than 12 hours and end no later than 2 hours prior to the snowfall. Should it be
required, occupied stands will be pre-treated manually, using the small hand-trollies in the snow cages.
6.3.
Snow Clearance – Runways and Taxiways
In order to maintain aircraft operations and maximise operational effectiveness during a snow event, each runway will
be closed in succession to facilitate snow clearance. After receiving the authority of ATC, the procedure starts with
clearing runway 09L-27R (Northern Runway), unless the operation determines otherwise.
Once the Northern runway has been cleared and de-iced, the runway team will move to the 09R-27L (Southern
runway), clearing a number of connecting taxiways along their way to 09R threshold. After clearing runway 09R-27L
(Southern Runway) the runway team will proceed to their muster point for the Northern Runway clearance while
clearing the connecting taxiways along their way.
The systematic clearance of each runway will continue until both runways are clear or the rate of snow fall has
diminished to a point where the de-icing agent is effective.
Page 12 of 25
6.4.
Taxiways
The taxiway clearing procedure is similar to the runway; however, to minimise clearing times and operational
disruption, up to four (4) teams are dedicated to the task. Each taxiway team is responsible for clearing and de-icing a
specific route. Each route includes a number of control points, at which the Team Supervisors must request
permission from ATC before proceeding.
Where possible, the convoys plough the snow to both sides of the taxiway. If there are stands on one side of the
taxiway, the snow is ploughed to the opposite side. If there are stands on both sides, the snow is ploughed to one of
the sides or to both sides, and then removed with a dedicated vehicle.
Snow Clearance snow bank profiles must meet the provisions of CAP168 at Appendix 2.
6.5.
Stands Clearance
3
4
In parallel to the runway and taxiway teams, up to 14 (fourteen) Stands Teams and 6 (six) Blades Teams will be
equipped and allocated to stand clearance. In addition to these, a specific Head of Stands Team in each terminal will
be responsible for keeping HoS clear of snow and ice in a snow event.
HAL Stand Supervisors, Blades Teams Leaders and Terminal Coordinators will maintain close liaison with the relevant
airlines and handlers to optimise clearance operations. Airline and handlers assistance to HAL stand clearance
operations is detailed within a collective MOU, Ground Handling Licence and Appendix 3 and 4 of the HSPA.
Details of stands snow clearance can be found at Appendix 3.
Self-help information is at Appendix 4.
6.6.
Airside Roads Clearance
Service roads, tug roads, ramp tunnels, the control post areas (airside), RV Points, Royal Suite Car Park and the Fire
Station Areas will be cleared by designated airside road teams. Within these areas, HAL Airside Road Teams will clear:
•
•
Tug roads:
·
Connecting Terminal 4 and CTA, from Link 28, through Grass Areas 14a & 15b, to Link 41. This road
passes behind the Instrument Landing System localiser of runway 09R.
·
The Terminal 4 Tug Road will close when the Low Visibility Procedure is in force.
Ramp tunnels:
·
Airside Road Tunnel (ART) and EAAR, connecting the Central Terminal Area with Terminals 5 and 2
respectively.
·
Cargo Tunnel, connecting the Central Terminal Area with the Cargo Apron, all intersections and Terminal
4.
·
Northern Airside Road and Southern Airside Road, connecting T5A with T5B.
In addition to the above, inter-stand clearway roads will be cleared by the stand teams. Controlled and uncontrolled
crossing roads will be cleared by the taxiway teams.
Areas Leased to Third-parties. Snow clearance of third-party leased areas is the responsibility of the lease holder.
HAL will assist the lease holders by clearing the snow off boundaries to enable clear visible delineation.
3
The number of stand teams deployed will be determined by the level of predicted snow fall, see Appendix 1, Activation Levels.
4
Six Blade Teams will be operating in Terminal 5A&B, Terminal 3 and Terminal 1&2 to clear highly occupied stands between aircraft movements.
Page 13 of 25
6.7.
Snow Stockpiles
Snow will be stockpiled in the interstand clearways at the back of stands 2m away from the double white lines.
Initially, the snow will be stockpiled on every other interstand clearway to facilitate an easier snow dump operation. If
these areas become full the remaining interstand clearways can be used to stockpile snow.
•
Snow will not be stockpiled in the interstand clearway leading to an uncontrolled crossing
•
Snow stockpiles will be no wider than 7m, no longer than 14m and no higher than 3m.
•
Telehandlers / Loading Shovels will be used to keep the stockpiles tidy and maximise the use of space on the
interstand clearways.
A number of aircraft parking stands and other specific areas in the airfield have been designated as snow dump areas.
Details of Snow Dump areas can be found on Figure 6.1.
Figure 6.1. Proposed Stand Snow Dump on site locations
Page 14 of 25
6.8.
Deactivation
Following the completion of clearance operations, the cessation of snowfall, a positive forecast from the
meteorological team, and consultation with the Bronze Commander and the Winter Operations Team, the AFM will
take the decision to cease HSPA operations.
HAL contingency teams and equipment will remain on shift until the airfield is: fully operational; all snow is clear from
operating surfaces; snow dumps are clear and equipment and resources are checked and made ready in preparation
for the next event. Staff will not be released until authorised by the AFM.
6.9.
HAL Anti/De-Icing Media and Equipment
A full list of HAL anti/de-icing media and equipment and snow clearance equipment refer to Appendix 5.
APPENDIX 1. ACTIVATION AND MOBILISATION
Timely activation is important to ensure that LHR is effectively mobilised in time to deal with a snow event. It is
intended that snow clearance teams will be activated and in place, prior to the first snow falling; nevertheless, it
should be recognised that the actual weather on the day may differ from that forecast and require amendments
to the timely actions detailed within the process detailed in this Appendix.
A1.1. Weather and Activation
An advanced weather forecast will determine LHR’s response to a snow event. As any forecast snow event draws
closer information will be required on the likely on set and accumulation of snowfall.
An initial decision on whether to trigger the activation plan will be taken 4 days prior to a forecast snow event
where possible. This will be based on the 5-day weather forecast provided by the Met Office. This information to
HAL, Airline operators and ground handlers is promulgated daily at the HOCC throughout the winter season.

Activation Decision-Making
Daily HOCC Call
When the weather forecast is predicting snow, the WOM will join the routine daily 09.30 HOCC conference call.
When appropriate, the conference call will discuss the latest Heathrow Response Forecast and LHR’s reaction to a
potential snow event.
HADACAB
Implementing capacity restrictions in Heathrow is managed through Heathrow ATM Demand and Capacity
Balancing group (HADACAB), whose remit is to control air traffic demand at Heathrow Airport during periods of
temporarily reduced capacity of >10% over >24 hours. Capacity implications resulting from snow conditions
require the invocation of the HADACAB in accordance with the relevant procedures (Local rule 4). The HADACAB
is attended by HAL, the Heathrow AOC, the Chair of the Heathrow Scheduling Committee, NATS, ACL and
representative airlines. For shorter periods of forecast snow disruption the daily Demand versus Capacity process
with apply.
•
HADACAB Activation. When a snow event is forecast, within HSPA criteria, the AOM or any relevant
Heathrow stakeholder can recommend the activation of HADACAB; however, this must be convened through
the AOM, who will inform the HAL duty director.
Page 16 of 25
Activating the HSPA.
When a snow event is forecast which meets the HSPA criteria the AFM, in liaison with Met, the WOM and
AfDM will activate the Airside Strategic Cell, Tactical Teams and contingency staff no less than 8 hours prior
to predicted snowfall. This decision should be made in consultation with the Head of Airside and the AOM.
Note: This call may occur earlier to allow staff further time to attend work and allow for sleeping patterns.
Activation Timeline: An airport activation timeline summary covering the events and actions from 4 days prior
to a snow event to the first snow falling is at Figure A1.2.
Activation Levels: The level of activation will differ according to the predicted impact; however, any staff not
activated during stages one and two will remain on standby to meet any increase in the predicted snow fall above
that forecast. The activation levels for predicted snow falls are as follows:
•
Level One: Less than 4 cm of snow – Airside Strategic Cell, Tactical Teams, all runway and taxiway teams,
airside road and tunnels teams and reduced deployment of stand teams to match the conditions forecast.
•
Level Two: 4 cm and above - All Airside Team staff and resources to match the conditions forecast.
Figure A1.2. Staff Activation Summary Timeline

APPENDIX 2. SNOW CLEARANCE
All activities involved in the removal of snow from the different parts of the airfield will be compliant with the
provisions of CAP 168 regarding snow bank profiles as follows:
Page 18 of 25
APPENDIX 3. STANDS CLEARANCE
Stands will be cleared according to the clearance status and priorities set-out in this Appendix.
Up to 14 (seventeen) stand clearing teams and 6 (three) Blades Teams comprising of Dyer and Butler contractors,
directed and coordinated by HAL staff will be provided for the clearance of stands and can be assisted as per the
Self-help criteria detailed (Appendix 4).
Memorandum of Understanding (MOU) HAL/AUC/AOC/Ground Handlers and Base Carriers
Winter Operations – Stand Clearance.
Airlines and Ground Handlers will be responsible for clearing away their equipment from stands prior to stand
clearance, ideally tidying up prior to an event in accordance with the Early Warning Indicator trigger points.
Airlines and handlers should co-operate and assist with pushing back aircraft off stand as required by HAL to
assist with stand clearance; this may include both facilitating pushback and brake riding responsibilities.
Stand status criteria is used to determine the usability of a stand and a stand’s priority for snow clearance. The
table below lists a set of guidelines which the Terminal coordinators and Ground Handlers must use for each of
the 3 stand states:
Stand Usability Guidelines (Universal for All Handling Agents)
USEABLE WITH CAUTION
RED
•Equipment is deemed safe to use with Users Risk assess.
•Users are aware of any iced-over areas on the stand.
•Use of self-help equipment has little or no impact.
LIMITED ACCESS
AMBER
•Taxiway centre lines are covered (if not cleared by Center-Line teams).
•Snow accumulation affects normal use of equipment.
•Use of self-help equipment has a significant impact.
NORMAL USE
GREEN
•Handlers are able to undertake turnaround duties as normal.
•Snow may be falling but majority melts on contact with ground (>50%).
•Conditions not suitable for formation of ice.
•CLEARED STAND
Table A3.1. Stand Usability Guidelines
It is the responsibility of the ground handlers, in conjunction with their specific HAL Terminal Supervisor, to agree
any stands status. The LHR stand status plan will be updated on the Situational Awareness Map (SAM) to reflect
this change.
Linked to the stand usability, is the stand clearance priority. Stand clearance priority takes into account both the
Stand Usability (stand condition) and the Stand Occupation. To facilitate ease of clearance, a vacant stand will
generally have the greatest priority for snow clearance.
Page 19 of 25
Airlines should liaise with the HAL Terminal Coordinator regarding the tactical and commercial importance of
each stand. For example, an occupied stand with an immediate requirement will take priority over any other
occupied stand.
The result of this is a stand priority matrix, which combines usability and occupation. The stand priority matrix is
illustrated below and stand clearance teams will work in the following order:
1. Highest Priority- Stand CAT A.
2. Medium- High Priority- Stand CAT B.
3. Low Priority- Stand CAT C.
4. Lowest Priority- Stand CAT D.

APPENDIX 4. STANDS CLEARANCE – SELF HELP
Airlines and Handlers will support the HAL teams’ clearance of snow from stands and equipment areas, following
this self-help process; nevertheless, it is recognised the level of support is subject to operational circumstances and
time of day. Where requested by HAL, the Airlines and Handlers should be prepared to assist and work on
clearing other stands which are contaminated in and adjacent to their normal areas of operation. Stands will be
cleared in accordance with the RAG status categorisation (Appendix 3).
Self Help Equipment
HAL will provide materials and tools for handlers for self-help in clearing stands. Pre-positioned prill or grit stocks
should be used by handlers and Airlines to support an instant need to anti ice, de-ice or enhance ground friction.
This should continue until stands can be re-treated in icy conditions or cleared in snow conditions. HAL has
deployed 50 stock cages with equipment including shovels, brooms, snow scoop shovels, prill hand scoops (10 of
each type) and one anti-icing hand trolley to aid clearance of snow. This will enable Handling Agents and Airlines
to self-help when clearing equipment, equipment parking areas, pedestrian areas and an aircraft’s immediate
footprint in advance of support of the HAL. Stillage area's and area’s given over for parking equipment are the
responsibility of the relevant handler or airline.
The locations of the self-help storage cages are as follows:

APPENDIX 5. HAL ANTI/DE-ICING MEDIA AND EQUIPMENT
De-Icing Products for Winter 2015-2016
Konsin Liquid De-icing Media – Supplied by Univar Limited
Konsin is a glycol-based, water-soluble, de-icing fluid, with a comprehensive corrosion inhibitor package. Konsin is
particularly suited to runway de-icing and will quickly remove any ice that has formed by converting it into a
Konsin/water solution with a markedly lower freezing point.
Clearway 6S Solid De-icing Media – Supplied by Univar Limited
Clearway® 6s melts ice by depressing the freezing point of water, and is active at temperatures to -15° C. Due to its
irregular granular shape, it will remain where spread. It can be used pre-wetted in combination with corresponding
liquid de-icers to obtain a rapid initial de-icing effect. It can also be applied alone to give a long residual anti-icing
effect under extreme weather conditions.
Vehicle Maintenance
EQUIPMENT MAINTENANCE AND SERVICING
All the equipment listed in the plan shall be serviced and maintained in accordance with manufacturer requirements
and technical best practice. In order to carry out routine or unforeseen maintenance, the full complement of
equipment may not be available for deployment on a snow event.
VEHICLE SERVICEABILITY AND CONSUMABLE PRODUCT TRACKING
Vehicles are prepositioned at forward locations where the operational teams inspect and report defects into Babcock’s
fleet maintenance. All snow equipment is a priority fault when reported. Any defects of Manoeuvring area vehicles
throughout an event will be tracked by the Babcock’s Base Manager reporting deficiency into SNOCO 1. All Apron
area vehicle defects will be tracked by Dyer and Butler and reported to SNOCO 2 via the Vehicle Support Coordinator.
Consumable Product levels will be monitored weekly outside an event and levels maintained to allow BAU anti icing.
Petrolink software and reported usage from the AfDM will provide necessary information on the requirement to reorder.
