3.
LANE A
switch off (max. RPM drop after stabilization must not exceed 250 RPM)
4.
LANE A
switch on
5.
LANE B
switch off (max. RPM drop after stabilization must not exceed 250 RPM)
6.
LANE B
switch on
7.
Throttle
reduce to idle run
8.
Left and Right fuel tank check
during engine run, the fuel pressure must not drop below
tolerated value in either of fuel tanks in use. During the change-over of fuel tanks in use, a short-
term fluctuation of fuel pressure can occure. After an appropriate fuel tank is selected, the fuel
pressure must return to appropriate values.
9.
Fuel pumps check
set up the engine run to 2000 RPM
switch on both fuel pumps
switch off the auxiliary fuel pump for a period of 5 seconds
and check the fuel pressure
switch on the auxiliary fuel pump
switch off the main fuel pump for a period of 5 seconds
and check the fuel pressure
switch on the main fuel pump
10.
Acceleration and engine power check
brake the aircraft by applying maximum brake effect
set up full engine power and hold for 10 seconds
the RPM shall reach 5200 RPM
set up the throttle to idle run
After the engine check is finished and operating temperature is reached, carry on take-off within max. 5
min. In case the aircraft is standing on spot for a long time when engine is running, the engine and its
compartment are not sufficiently cooled by the airflow. This may be a cause of overheating and
damage of the engine and composite structure in its compartment.
Notes:
The sensors of LANE A and LANE B have different inputs. During the check of LANES and ignition,
some values on EMS screen are not displayed depending on activation of the LANES.
If the EMS power supply fails (alternator A), the ECU (engine control unit) automatically switches one-time
over to the second power supply (alternator B). While alternator B runs, there is no drop of voltage. The
engine is running, but the battery is not being charged!
