Emergency Procedures Flashcards
Power failure due to engine failure indication
Change in noise level, nose left yaw, an oil pressure light or decreasing engine RPM
In case of power failure , possible indication and procedure
Engine or drive system failure, indicated by low RPm horn.
Immediately lower collective to enter auto rotation.
Power failure caused by drive system indication
It’s indicated by an unusual noise or vibration, nose right or left yaw,mor decreasing RPM while engine RPM is increasing.
Engine fire during start on ground
. Continue to attempt start
. If engine starts run at 50-60 RPM for a short time, shut down and inspect for damage.
. if engine refuses to start shut off fuel and mastery battery switch
. Extinguish fire with fire extinguisher, wool blanket or dirt. Inspect for damage.
Fire in flight
Enter auto rotation
.master battery off
.cabin heat off
.Cabin vent on
.if engine is running perform normal landing and immediately shut off fuel valve.
. If engine is not running, immediately shutoff fuel valve and perform autorotation landing.
Electrical fire in flight
.Master battery off
.ALT switch off
.Land immediately
.Extinguish fire and inspect for damage.
Tachometer failure
If rotor or engine tach malfunction in flight, use remaining tach to monitor RPM.
If it’s not clear which tach is malfunctioning or both are malfunctioning, allow GOV to to control RPM and land as soon as practical.
Governor failure
If the engine RPM GOV malfunctions, grip throttle firmly to override governor, then switch governor off. complete flight using manual throttle control.
Oil warning light
Indicates loss of engine power or oil pressure.
Check engine tach for power loss
Check oil pressure gauge
-if pressure loss is confirmed land immediately
MR TEMP
Indicates excessive temperature of main rotor gearbox.
If light accompanied by vibration, noise, or temperature rise, land immediately.
MR CHIP
Indicates metallic particles in main rotor gearbox.
If light accompanied by vibration, noise, or temperature rise, land immediately.
TR CHIP
Indicates metallic particles in tail rotor gearbox.
If light accompanied by vibration, noise, or temperature rise, land immediately.
Low fuel warning light
Indicates approximately 1gallon of useable fuel remaining in an all aluminum tank, the engine will run out of fuel in approximately 5 mins.
For a bladder style tank it indicates that approximately 1.5gallon of fuel is remaining and will last for about 10mins.
Clutch
Indicates clutch actuator circuit is on
If the lights comes on and does not go off approximately 10secs, pull clutch circuit breaker and land as soon as practical.
If there are other indication of drive system failure, reduce power and land immediately( prepare for autorotation.)
ALT
Indicates low voltage and possible alternator failure.
Turn off nonessential electrical equipments and switch alt off and back on after one sec to reset voltage relay.
If light stays on, land as soon as practical.
