Emergency Procedures Flashcards
1
Q
Power failure between 8 feet and 500 feet
A
- Lower collective to maintain RPM
- Adjust collective to keep RPM between 97 and 108%
- Maintain airspeed, at 40 feet begin flare to reduce rate of descent and for airspeed
- At 8 feet level ship, raise collective to cushion landing, touchdown straight and level
2
Q
Power failure below 8 feet
A
- Apply right pedal to prevent yawing
- Allow helicopter to settle
- Raise collective prior to touchdown to cushion landing
3
Q
Max glide configuration
A
- Airspeed approximately 90 knots
- Rotor RPM approximately 90%
- One nautical miles per 1300 feet
4
Q
Minimum rate of descent
A
- Airspeed approximately 55 knots
- Rotor RPM approximately 90%
- Minimum rate of descent is 1350 fpm. One nautical mile per 1500 feet
5
Q
Air restart procedure
A
- Mixture off
- Throttle closed
- Engage starter while simultaneously applying mixture while cranking
- Air restart procedure not recommended below 2000 feet
6
Q
Emergency water landing (Power off)
A
- Establish autorotation
- Unlatch doors if time permits
- Apply lateral cyclic with water contact
- Exit and clear aircraft when rotor stop
7
Q
Emergency water landing (Power on)
A
- Descend to hover above water
- Unlatch doors
- Allow passengers to exit
- Fly clear of passengers to avoid injury
- Turn battery and alternator off
- Rolloff throttle, Full collective raise with water contact, apply lateral cyclic to stop rotors, clear aircraft when rotor stop
8
Q
Loss of tail rotor thrust in-flight
A
- Very are indicated by uncorrectable right nose yaw
- Enter autorotation
- Maintain 70 knots
- Select landing area, detent throttle, perform autorotation landing
9
Q
Engine fire during start up
A
- If cranking continue and attempt to start
- If engine starts let run at 60 to 70%, then normal shut down, inspect for damage
- If engine fails to start turn off master switch and fuel shut off valve
- Extinguish fire then inspect for damage
10
Q
Fire in flight
A
- Immediately enter autorotation
- Master switch off if time permits
- Turn cabin heat off, open cabin vent if time permits
- If engine is running perform normal landing and immediately turn off fuel
- If engine stops turn off your valve perform autorotation landing
11
Q
Electrical fire
A
- Master switch off
- Alternator switch off
- Land immediately
- Extinguish fire and inspect for damage
12
Q
Power failure above 500 feet
A
- Lower collective immediately to maintain rotor RPM
- Establish glide at 70 Knots
- Adjust collective to keep RPM between 97 and 108%
- So like landing spot, into the wind if possible
- Attempt to restart, if able
- If unable to restart, nonessential switches and fuel valve off
- At 40 feet begin flare to reduce rate of descent and forward airspeed
- At 8 feet level ship, raise collected to cushion landing, touchdown straight and level
13
Q
Tachometer failure
A
- If engine or rotor tachometer fails and flight use remaining tachometer to monitor RPM
- If both tachometers fail allow governor to control RPM and land as soon as practical
14
Q
When are the low RPM warning system and governor inoperative
A
With both the master and alternator switches off
15
Q
Hydraulic system failure
A
- Verify hydraulics switch is on
- If hydraulics not restored turn switch off
- Adjust airspeed and flight condition as desired
- Land as soon as practical preferably running landing
