4.3 Engine Warm-up
• Allow the engine to warm up for approximately 2 minutes at
idle speed.
• Then increase the propeller speed to 1400 rpm until the oil
temperature has reached 50°C and the coolant temperature
has reached 60°C.
4.4 Before Takeoff Check
4.4.1 FADEC and propeller pitch functional check
a) Set the load selector to idle (both FADEC indicator lights
should be off).
b) Press and hold the FADEC test button for the duration of the
entire procedure.
c) Both FADEC A and FADEC B lights illuminate and the
PROPELLER SPEED increases.
(Propeller speed target 1100-1300PropRPM)
d) The system then automatically switches to the FADEC B
(only the B light is on).
e) The propeller governor is activated; the propeller speed
decreases.
(Propeller speed target 800-900PropRPM)
f) The system automatically switches to the FADEC A (only
the A light is on), the propeller speed increases.
(Propeller speed target 1100-1300PropRPM)
g) The propeller governor is activated; the propeller speed
decreases.
(Propeller speed target 800-900PropRPM)
WARNING: For operation with diesel, the aircraft must not be started if the
temperature of the fuel in the tank is below -5°C (-10°C if Liqui
Moly „Diesel Fliess-Fit“, No.: 5130 is added according to the
manufacturer’s specifications).
If you do not know what fuel grade is in the tank, always assume
it is additive-free Diesel.
Note: The engine instrumentation has to be observed during the
subsequent steps.
WARNING: If the indicator lights do not illuminate at this time, a takeoff must
not be attempted with the aircraft.
