Emergency Procedures Flashcards
Land as soon as practical
Landing site is at pilot’s discretion based on nature of problem and available landing areas. Flight beyond nearest airport is not recommended.
Power failure (general)
nose left yaw.
In case of power failure, immediately lower collective to enter autorotation.
CAUTION
Aft cyclic is required when collective is lowered at high speed.
CAUTION
Do not apply aft cyclic during touchdown or ground slide to prevent possible blade strike to tailcone.
Power failure above 500’
- Lower collective immediately to maintain rotor RPM.
- Establish a steady glide at approximately 65 KIAS. (For maximum glide distance, see page 3-3.)
- Adjust collective to keep RPM between 97 and 110% or apply full down collective if light weight prevents attaining above 97%.
- Select landing spot and, if altitude permits, maneuver so landing will be into wind.
- A restart may be attempted at pilot’s discretion if sufficient time is available (See “Air Restart Procedure”, page 3-3).
- If unable to restart, turn unnecessary switches and fuel valve off.
- At about 40 feet AGL, begin cyclic flare to reduce rate of descent and forward speed.
- At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude with nose straight ahead.
Power failure under 500
- Lower collective immediately to maintain rotor RPM.
- Adjust collective to keep RPM between 97 and 110% or apply full down collective if light weight prevents attaining above 97%.
- Maintain airspeed until ground is approached, then begin cyclic flare to reduce rate of descent and forward speed.
- At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude and nose straight ahead.
Emergency water landing (power on)
- Descend to hover above water.
- Unlatch doors.
- Passenger exit aircraft.
- Fly to safe distance from passenger to avoid possible injury by rotors.
- Switch battery and alternator OFF.
- Roll throttle off into overtravel spring.
- Keep aircraft level and apply full collective as aircraft contacts water.
- Apply lateral cyclic to stop rotors.
- Release seat belt and quickly clear aircraft when rotors stop.
Max glide configuration
Airspeed approx. 75 KIAS.
Rotor RPM approx. 90%
Minimum decent rate 53 knots at 90% RPM
Air restart procedure
Mixture- Full rich
Primer- down and locked
Throttle- closed, then cracked slightly
Actuate the starter with left hand
Tach failure
Use remaining tach to monitor RPM’s. if it is not clear which tach failed or if both fail, allow governor to control RPM’s and land as soon as practical
Governor failure
grip throttle firmly to ovveride the governor, then switch governor off. continue flight with manual throttle.
Oil light on
check engine tach for power loss. check oil pressure gage and if pressure loss is confirmed, land immediately.
MR temp, MR/TR chip
If light is accompanied by any indication of a problem or temp rises, land immediately. if no other problems, land as soon as practical.
Low fuel
indicates one gallon & 5 minutes in aluminum tank and 1.5 gallons & 10 minutes in bladder tank. Land immediately.
Clutch light on
Count to 10, if light is still on pull clutch breaker and land as soon as practical. if any other indications of problems, reduce power and land immediately, be prepared to conduct an auto rotation.
ALT light
turn off all non essential electrical equipment and switch alternator off and back on and land as soon as practical.
Carbon monoxide
Shut off heater, open nose and door vents.
if in a hover, transition to forward flight. If physical symptoms arise, land immediately.
