4.4. Engine Check
1. Brakes on
2. Throttle 4000 RPM
3. Switch off LANE A max. RPM drop after stabilization must not exceed 180 RPM
4. Switch on both LANE A and B 4000 RPM
5. Switch off LANE B max. RPM drop after stabilization must not exceed 180 RPM
6. Throttle reduce to idle run
7. 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 pressure drop may occur. After the appropriate fuel tank is selected, the fuel pressure must
return to appropriate values.
8. Fuel pumps check set the RPM up 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
9. 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 5000 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 supplies fails (alternator A), the ECU (engine control unit) will automatically switches
one-time over to the second EMS power supply (alternator B). While alternator B runs, no power drop is
observed. The engine is running, but the battery is not being charged!
4.5. Procedures Before Take-off
1. Brakes on
2. Rescue system unlock (if equipped with)
3. Foot-operated steering free travel
4. Hand-operated steering free travel
5. Flaps position I.
6. Fuel valve open (left/right) for appropriate fuel tank intended to use
7. Fuel pumps both ON (main and auxiliary)
8. MASTER SWITCH switched on
9. START POWER switched off (in “FLIGHT POSITION”)
