Motor warm-up procedure
No warm-up is necessary.
Taxi
Release parking brake if set and release the handbrake. Taxiing technique does not differ from other
aircraft equipped with a steerable nose wheel. Prior to taxiing it is essential to check the wheel brakes
for proper braking action.
Holding point
Make sure motor temperatures at full power range are within operational limits.
Make sure the safety belts are fastened and doors closed and secured at all three closing points.
For short field operations extend flaps 25
o
. For all other operations extend them to 15°.
Power cut off.
Before takeoff power check
1. Check PARKING BRAKE is ENGAGED
2. INCREASE POWER LEVER to FULL
3. Check POWER INDICATION >= 56 kW (EPSI570 - flight page)
4. CUT OFF POWER LEVER
5. Check BATTERIES IN “ACTIVE” MODE (EPSI570 - system page)
6. Check ENGINE and BATTERY TEMPERATURES (EPSI570 - flight page)
7. Check NO CAUTIONS or WARNINGS (EPSI570 - flight page)
CAUTION! At FULL POWER the motor RPM should be between 2000 and 2500, while the mo-
tor power should be 56 kW or more. If this is not the case, do not proceed with flight and check
the system for correct installation.
CAUTION! Max battery temperature before takeoff is 40
o
C (check section 3 - Limitations).
Temperatures higher than 40
o
C at takeoff may result in high in-flight battery temperatures
when OAT is high or high power settings are applied. See also section 6 - Emergency procedures.
