- To help the pilot in his decision process, three recommendations are used
- LAND IMMEDIATELY
- LAND AS SOON AS PRACTICABLE
- Emergency conditions are urgent and require landing at the nearest landing
site at which a safe landing can be made.
- Emergency conditions are urgent and require landing at the nearest landing
- CONTINUE FLIGHT
- Continue flight as planned. Repair at the destination according to
maintenance manual.
- Continue flight as planned. Repair at the destination according to
NOTE: The emergency procedures describe the actions the pilot must
take, relative to the various possible failures that can occur.
However, depending on the many variable external environments, such as
the type of terrain flown over, the pilot may have to adapt to the situation
according to his experience
- What are the only situations that require an ‘autorotation’ LAND IMMEDIATELY?
-
Main engine drive failure
- Can be detected by
- Yaw acceleration, nose to the right,
- Engine noise level decreases,
- Tachometer needles desynchronization on the EPM (engine
decreases) - OIL P warning on the EPM and OIL P red light coming ON.
- Plasma beeper,
- Rotor speed decreasing and “low NR” horn.
- Can be detected by
-
Engine fire
- EPM warning caption *RED FIRE Box*
-
Tail rotor failure
- Charactarised by a strong yaw to the left
Power failures
General
- Engine Failure can be detected by
- Caution
- Yaw acceleration, nose to the right,
- Engine noise level decreases,
- Tachometer needles desynchronization on the EPM (engine decreases)
- OIL P warning on the EPM and OIL P red light coming ON.
- Plasma beeper,
- Rotor speed decreasing and “low NR” horn.
- Caution : A slow decay in engine power, caused by carburetor icing or air filter clogging, is compensated by the governor and can be overlooked by the pilot. The MLI indication will not change while in PWR mode, but will rapidly shift to FLO mode, then increase to 100%.
Power failures
General
- Primary Transmission Failure can be detected by
- Yaw acceleration, nose to the right,
- Engine noise level increases,
- Tachometer needles desynchronization on the EPM (engine increases) Eventual engine overspeed only if the governor is OFF
- Rotor speed decreasing and “low NR” horn.
In case of a primary transmission failure, apply following power failure
actions. Roll off the twist grip as soon as possible.
Power failures
Hover below 8 feet AGL
- The helicopter will normally exhibit little or no tendency to depart in pitch
or roll, hence requiring little correction: What are the 3 procedures?
- Use left pedal input to counter yawing to the right,
- Cushion landing by raising collective, until high pitch stop if necessary,
- Once landed, lower the collective.
Power failures
During take off
- Take-off acceleration is the most critical situation for a power failure to
occur, requiring moderate and rapid pilot reaction : What are the 7 procedures?
- Use left pedal input to counter yawing to the right,
- Use aft cyclic to level the helicopter,
- Before having reached 30 kt IAS, do not lower the collective,
- If IAS is above 30 kt IAS, slightly pitch up while slightly lowering the collective, if needed, to prevent climbing,
- When approaching the ground, raise the collective to cushion contact,
- Use pedals to minimize ground drift,
- Once stopped, lower the collective.
Power failures
Other in-flight power failures
- All cases: There are 10 steps.
- Lower the collective immediately and maintain full down,
- Use pedals to control yaw,
- Maintain IAS between 30 and 50 kt IAS (50 kt IAS recommended),
- Select landing area and manoeuvre to land into the wind,
- Adjust collective to centre NR in green arc,
- When the landing is ensured, consider engine restarting if enough time is available. Refer to page 3-5.
- At about 60 feet AGL, apply aft cyclic to raise the helicopter nose smoothly and continuously. Below 50kt IAS, this manoeuvre will not stop sink rate.
- As ground closes-on, apply forward cyclic to level the helicopter while raising the collective to stop sink rate.
- Use pedals to minimize ground drift,
- Once stopped, lower the collective.
* *Note** : Average manoeuvre requires about 200 to 300 m (650 to 1000
feet) free of high obstacle.
