Emergency Procedures Flashcards
Power Failure Above 500 AGL
- Lower collective immediate to maintain RPM and enter normal Auto.
- Establish a steady glide at approx. 65 KIAS
- Adjust collective to keep RPM in the green arc or apply full down if light weight prevents getting above 97%
- Select landing spot and if alt permits maneuver so landing will be into wind.
- A restart may be attempted at pilot’s discretion.
- If unable to restart turn off unnecessary switches and shut off fuel.
- At about 40 ft AGL begin cyclic flare to reduce rate of descent.
- At about 8 ft AGL apply forward cyclic to level the ship and raise collective to cushion landing.
Power Failure Between 8 and 500 AGL
- Lower collective immediate to maintain rotor RPM
- Adjust collective to keep RPM in the green arc or apply full down if light weight prevents getting above 97%
- Maintain airspeed until ground is approached, then begin cyclic flare to reduce descent and forward speed.
- At about 8 ft AGL apply forward cyclic to level the ship and raise collective to cushion landing.
Power Failure Below 8 AGL
- Apply right pedal as required to prevent yaw
- Allow aircraft to settle
- Raise collective just before touchdown to cushion landing.
Max Glide Distance Config
- Airpseed 75 KIAS
- Rotor RPM 90%
- Best glide ratio is about 4:1 or 1 Nautical mile per 1500 feet AGL
Air Restart Procedure
- Mixture-full rich
- Primer-down and locked
- Throttle-closed, then cracked slightly
- Actuate starter with left hand.
Caution:do not attempt restart if engine malfunction is suspected, or before safe auto established.
Loss of Tail Rotor Thrust during forward flight
- Enter Auto
- Maintain at least 70 KIAS if practical
- Select landing site, roll throttle off to overtravel spring, perform auto landing.
Loss of Tail Rotor Thrust during hover
- Roll throttle off into overtravel spring and allow aircraft to settle.
- Raise collective just before touchdown to cushion landing.
Engine Fire during start on ground
- Cranking-Continue and attempt to start which would suck flames and excess fuel through the carburetor
- If engine starts, run at 50-60% RPM for a short time, shut down, inspect for damage
- If engine fails to start, shut off fuel and master battery
- Extinguish fire with fire extinguisher, wool blanket, or dirt
- Inspect for Damage
Fire in Flight
- Enter auto
- Master batter off
- Cabin heat off
- Cabin vent on
- If engine is running, perform normal landing and immediately shut off fuel valve
- If engine stops running, shut off fuel valve and execute auto landing
Electrical Fire in Flight
1.Master Battery off
2.Alternator off
3.Land immediately
4.Extinguish fire and inspect for damage
Caution:Low RPM warning system and governor are inoperative when master battery and alternator are off.
Oil Light
Indicates loss of engine power or oil pressure. Check engine tach for power loss. Check oil pressure gage and, if pressure loss confirmed land immediately.
MR Temp
indicates excessive temp of main rotor gearbox. If accompanied by any indication of a problem (noise, vibration, or temp rise) land immediately. Otherwise land as soon as practical.
MR Chip
Indicates metallic particles in main rotor gearbox.If accompanied by any indication of a problem (noise, vibration, or temp rise) land immediately. Otherwise land as soon as practical.
TR Chip
Indicates metallic particles in tail rotor gearbox. If accompanied by any indication of a problem (noise, vibration, or temp rise) land immediately. Otherwise land as soon as practical.
Low Fuel Light
Indicates approx 1 gallon of usable fuel remaining. Engine will run out of fuel after 5 mins at cruise power.
