4.8.3 IN-FLIGHT GENERATORS FAILURE
During flight if one of the two generators fails the ECU automatically switches over to supply
the engine management system.
In case of a failure of both generators, in order to avoid the engine stoppage, the engine
management system has to be powered by an external backup system using the battery
backup switch.
In both cases, the failure is indicated by the fixed lighting in DANGER mode of the warning LED
“Line A” and/or “Line B”.
Since it is not possible to distinguish the two cases, the pilot has to proceed as follows.
A. Fixed red LED 1 “Line A”:
1. Trim the gyroplane at safe altitude and speed (if flying)
2. Line A switch...............................OFF
3. Line A switch...............................ON
If after 5 seconds the LED is ON:
4. Execute the generator failure emergency procedure (described below)
If after 5 seconds the LED is OFF:
4. Continue flying monitoring tension values till destination
5. Once landed, contact the assistance service
B. Fixed red LED 2 “Line B”:
1. Trim the gyroplane at safe altitude and speed (if flying)
2. Line B switch ..............................OFF
3. Line B switch ..............................ON
If after 5 seconds the LED is ON:
4. Execute the generator failure emergency procedure (described below)
If after 5 seconds the LED is OFF:
4. Continue flying monitoring tension values till destination
5. Once landed, contact the assistance service
