5.5 Low fuel pressure
Fuel pressure indication is provided.
The internal EECU voter switches automatically to the Standby-ECU further the corresponding fuel pump
will be switched active.
Both fuel pumps can be activated by a switch if the behaviour is not considered as sufficient.
5.6 High Fuel Temperature
● Reduce power
● Monitor fuel temperature
– if the fuel temperature decreases into green continue operation in the green range
– otherwise land as soon as possible
5.7 High Coolant Temperature
Reduce power
Monitor coolant temperature
– if the coolant temperature rises into green continue operation in the green range
– otherwise land as soon as possible
5.8 Engine Fire
● Fuel shut-off valve closed
● Engine master switch off
● Prevent continued rotation due to wind milling, if possible.
5.9 Electric power supply out of range
● switch-off alternator
● switch–on alternator
If the failure persists continuous operation is possible as long as battery power supply is sufficient.
5.9.1 Restart in-flight by windmilling
In case of an engine malfunction determine the root cause and only continue in case a safe
restart is possible.
1. Max. demonstrated altitude for immediate restart by windmilling: 15.000ft
2. Max. demonstrated altitude for restart after 10 min. and ambient air temperature higher than
ISA by windmilling: 10.000ft
3. Max. demonstrated altitude for restart after 5 min. and ambient air temperature between ISA
and ISA minus 10 °C by windmilling: 10.000ft
4. Max. demonstrated altitude for restart after 2 min. and ambient air temperature below ISA
minus 10 °C by windmilling: 10.000ft
5. Airspeed: see applicable Aircraft Flight Manual
6. Power Levers – “IDLE”
7. Engine Master – “ON”.
Move power lever slightly forward to a power rating assuring that the referring engine is
delivering thrust, as a rotating propeller is not a guarantee for a running engine.
