LAND ASAP
loss of tail rotor thrust in hover
Collective: Lower immediately
ECL’s: Both OFF (if time and conditions permit)
Collective: As required to cushion touchdown
Loss of tail rotor thrust in powered flight
Collective: Lower immediately
Enter EMERGENCY
AUTOROTATION as per
procedure.
Airspeed: 70 KIAS
ENG MODE 1 & 2: Set to IDLE
Tail rotor control failure in forward flight
If time and conditions permit,
perform controllability check.
Approach: Perform keeping nose
to the left.
Landing: Touchdown at lowest airspeed
obtained in the controllability check.
ECL’s: Retard to OFF only once
helicopter has stopped
OIL HOT
Engine oil temp hot
CONFIRM OIL TEMP
IF ABOVE 110 DEGREES (if not –> proceed with flight)
ACHIEVE SAFE OEI FLIGHT
ENGINE SHUTDOWN IN AN EMERGENCY
LAND ASAP
ENGINE OIL PRESSURE HIGH
On affected engine:
- Select MAIN page on MFD2
- Monitor engine parameters
Achieve safe OEI flight
On affected engine:
Shut down engine using
ENGINE SHUT DOWN IN
EMERGENCY procedure.
Land as soon as practicable
OIL CHIP
Select MAIN page on MFD2
- Check affected engine and
engine oil parameters
Achieve safe OEI flight
Reduce power by lowering collective
As soon as practicable, carry out
ENGINE SHUTDOWN IN AN
EMERGENCY procedure.
Land as soon as
practicable
MGB OIL CHIP / TGB OIL CHIP
Activate CHIP BURN switch
momentarily and release.
It is permitted to activate the CHIP
BURN up to 3 times to clear a chip.
