4.1.4 Before Take-off Check
1. Engine Instruments – CHECKED
2. Fuel Temperature – CHECKED (refer to chapter 2.5.6.3 and 2.5.7.3 Fuel)
3. Power Levers – “IDLE”
4. ECU-Self Test – PERFORM
The ECU cockpit switch (voter switch) must remain in the “Auto”-Position throughout the
whole self test procedure. Manually selecting ECU “A” or “B” prevents the self test from
successfully testing the switch-over functionality causing the self test to abort with an error
indication (“ECU Caution”-Lamp will remain ON).
5. Power Lever Max (100% / 10 sec) – CHECK LOAD, CHECK RPM, CHECK Fuel Flow
4.1.5 During Flight Check
Engine/propeller speed and all temperatures and pressure must be monitored constantly during flight.
For operation optimums refer to chapter 2.5.
4.1.6 Engine OFF
The engine has to run for minimum 1 minute at maximum 10% of full load, before shut down.
After turning the engine master OFF, wait until 20 sec. before turning the battery master
OFF unless otherwise defined in the aircraft flight manual. This ensures that engine and
flight data can be written to non-volatile memory before removing power.
4.2 Low Oil Pressure
It may occur that operation of the engine after landing at idle speed and high oil temperature leads
to a low oil pressure warning. If this is the case push the power lever forward until the caution
disappears.
