Start-Up:
- Alternator OFF (to be tried if it works better this way)
- One/Two injections + ¼ inch
- Pump (normally NO - only check if working before) –required in case of heat (gas)
(plane manual claims to put the pump when engine is warm)
- Start (On Both)/Alternator ON/Oil Check
- Lights
Pre-Start Checks:
- After warm-up: Magneto (1800), Rechauffe, Succ, Pitch (3x), Mixture (1-3x), Ralenti
- Alternator CHECK
- and usual: VVRPTCC
(verrière, volets [10deg], réch., pompe [not on!], transpondeur [auto], cowl, comp)
Variable Pitch:
- Propeller (Blue nob) selects propeller/engine RPM
- Throttle (Black) controls manifold pressure (and indirectly controls propeller pitch
(through the action of the prop governor)
- Take-off: maximum RPM/power is achieved (not the case for fixed-pitch prop)
- Prop oil thickens at low temperatures -> change prop setting every 15min?
(from time to time?)
- Idle throttle causes flat pitch (high drag airplate)
- Higher MP with same RPM causes more torque (and p-factor)
- Loss of oil pressure -> FLAT pitch (high RPM, high drag)
- Lower cruise RPM: less noise and better for turbulences
Increase/Reduce Power
- Increase: Mixture/Propeller/Throttle (from RIGHT to left)
- Decrease: Throttle/Propeller/Mixture (from LEFT to right)
Logbook:
- Marking down fuel + times, legs, etc.
- Time from transponder (take-off/land)
Leaning and Fuel Procedure:
- EDM 700:
o Buttons:
 Left: Step (STP)
 Right: Lean-Find (LF)
o Switch:
 EGT mode
 FF mode
 All
o Manuel mode: press STP
o Automatic mode: press LF then STP
o Percentage/Normalized view: hold LF for 5s
o Leaning Procedure 1 (Rich of Peak!):
 Pre-lean below 50deg of estimated peak –T (???)
 Wait 30s for temperatures to stabilize
 Tap LF (exhaust T of the hottest Cyl left)
 Lean at ~5deg/s
 Lean-find will get active once you have a 15deg rise in EGT
 Stop leaning when you see ‘LEANEST’ on the display
 Left: T of first EGT to Peak
• Tap LF then you see the delta-T to Peak
 While column flashes, enrich until you’ve reached the desired EGT (???)
o Procedure 2 (Lean of Peak!):
 Tap LF and then immediately hold STP and LF until you see “LEANL”
 Lean at ~5deg/s
 Lean-find will get active once you have a 15deg rise in EGT
 “LEANEST” will be displayed when the 1st cylinder peaks
• Display will change
 Continue leaning until the last EGT peaks -> “RICHEST”
 The display shows the delta-T to Peak for the last Cylinder
 Hold LF button: peak of the richest on the left, spread on the right
(change of fuel flow from the 1st and the last EGT to peak)

o Fuel options:
 When EDM switches on: put FUEL (STP for no change, LF for add)
 Add: press LF (“FILL+”) then STP
•
Press STP (“ADD” and “0”), hold LF (press to decrease), then STP
Instruments:
Auto-Pilot:
- To follow GPS: the GNS430 needs to display ‘GPS’ in the lower part
- If the GNS430 displays ‘log’ then the autopilot follows the LOC
(button CDI for changing)
