Vad är viktigt att göra vid en autorotation?
- Nos upp, collective ner
- Gör bedömning
- Stället ut
- Mayday
- Flare 150 ft ca
Single engine failure - Procedure
- Reduce collective to within limits
- Achieve safe OEI flight
- Engine shutdown in an emergency
- Land as soon as practicable
Engine shutdown in an emergency - procedure
- EMS –> OFF
- ECL –> OFF
- FUEL PUMP –> OFF
- FUEL VALVE –> CLOSED
- XFEED –> CLOSED
- GENERATOR - OFF
- HEATER –> OFF
(- SHUT-OFF 1/2 –> OFF)
( - MIX –> OFF) - FUEL –> MONITOR
LAND AS SOON AS PRACTICABLE
ENGINE FIRE - PROCEDURE
INITIATE IMMEDIATELY EMERGENCT DESCENT
COLLECTIVE BELOW 50% PI
EMS –> IDLE
CONFIRM ENGINE FIRE
ECL –> OFF
PRESS S/OFF FIRE PB

IF FIRE PERSISTS
BTL 2
LAND ASAP/ LAND IMMEDIATELY
ENG OIL PRESS
CHECK PRESSURE + TEMP
ACHIEVE SAFE OEI FLIGHT
EMS –> IDLE
ENGINE SHUTDOWN IN AN EMERGENCY
LAND AS SOON AS PRACTICABLE
MGB OIL PRESS
CHECK PRESSURE
IF BELOW 2 BAR / IF NOT
REDUCE POWER / CONTINUE FLIGT
LAND ASAP / LAND AS SOON AS PRACTICABLE
MGB OIL HOT
CHECK TEMP
IF ABOVE 120 / IF NOT
REDUCE POWER / CONTINUE FLIGHT
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
