The flashcards below were created by user cmnaranjo on FreezingBlue Flashcards. What would you like to do?


  1. Define land immediately.
    Land on the nearest clear area where a safe normal landing can be performed. be prepared to enter autorotation during approach, if required
  2. Define land as soon as possible
    Land at the nearest airport or other facility where emergency maintenance may be performed
  3. What do you do for a power failure above 500 AGL?
    • lower collective immediately t maintain RPM. and enter normal auto rotation.
    • establish steady glide at approx. 70 KIAS
    • adjust collective to keep RPM in green ARC, or apply full down collective if light weight prevents attaining above 97%
    • Select landing spot, if altitude permits maneuver so landing will be into the wind
    • A restart may be attempted at pilots discretion if sufficient time is available
    • if unable to restart turn off unnecessary switches and turn off fuel
    • at about 40 FT AGL begin cyclic flare to reduce decent rate and forward speed
    • at about 8 FT AGL apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. touch down with level attitude with nose straight ahead
  4. What do you do for a power failure between 8 FT and 500 FT AGL?
    • Lower collective immediately to maintain rotor RPM
    • adjust collective to keep RPM's in the green ARC. apply full down collective if light weight prevents attaining 97%
    • maintain airspeed until ground is approached, then begin cyclic flare to reduce rate of decent and forward speed
    • at about 8 ft AGL apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. touch down with skids level and the nose straight ahead
  5. What do you do for a power failure below 8 FT AGL?
    • Apply right pedal as required to prevent yawing
    • Allow rotorcraft to settle
    • Raise collective just before touchdown to cushion landing
  6. What is the maximum glide distance configuration?
    • Airspeed approx. 90 KIAS
    • Rotor RPM approx. 90%

  7. What is the minimum rate of descent configuration?

    • Rotor RPM approx. 90%
    • Minimum rate of decent is about 1350 FT per minute

  8. What are to steps for an air restart procedure?
    • Mixture-Off
    • Throttle-Closed
    • Starter-Engage
    • Mixture-Move slowly rich while cranking
    • **Air restart not recommended below 2000 FT AGL**
  9. What do you do when ditching with power off?
    • Follow same procedures for power failure over land until contacting water
    • apply lateral cyclic when aircraft contacts water to stop blades from rotating
    • release seatbelts and quickly clear aircraft when blades stop rotating
  10. What do you do when ditching with power on?
    • Descend to hover above water
    • unlatch doors
    • passengers exit aircraft
    • fly to safe distance from passengers to avoid possible injury by blades
    • switch off battery and alternator
    • roll throttle off into detent spring
    • keep aircraft level and apply full collective as aircraft contacts water
    • apply lateral cyclic to stop blades from rotating
    • release seat belt and quickly clear aircraft when blades stop rotating
  11. What do you do when you get a loss of tail rotor thrust during forward flight?
    • failure is indicated by nose right yaw which can not be corrected by left pedal
    • immediately enter auto rotation
    • maintain at least 70 KIAS if practical
    • select landing site, roll throttle off into detent spring, perform auto rotation landing
  12. What do you do when you get a loss of tail rotor thrust during hover?
    • failure is indicated by nose right yaw which can not be corrected by left pedal
    • immediately roll throttle off into detent spring and allow aircraft to settle
    • raise collective just before touchdown to cushion landing
  13. What do you do for an engine fire during start on ground?
    • Cranking - continue to attempt start which would suck flames and excess fuel into engine
    • if engine starts, run at 60-70% RPM for a short time, shut down and inspect for damage
    • if engine fails to start, shut off fuel and mastery battery switch
    • extinguish fire
    • inspect for damage
  14. What do you do for an engine fire during flight?
    • Enter autorotation
    • Master battery switch - off (if time permits)
    • Cabin heat - off (if time permits)
    • Cabin vent - off (if time permits)
    • if engine is running, perform normal landing and immediately shut off fuel valve
    • if engine stops running, shut off fuel valve and execute autorotation landing
  15. What do you do for an electrical fire during flight?
    • Master battery switch - off
    • Alt switch - off
    • Land immediately
    • Extinguish fire and inspect for damage
  16. What do you do for tachometer failure?
    • Use the remaining tach to monitor RPM.
    • if it is not clear which tach is malfunctioning or if both are, allow the governor to control RPM
    • Land as soon as practical
  17. What do you do for a hydraulic system failure?
    • Adjust airspeed and flight condition as desired for comfortable control
    • HYD Switch - verify ON
    • if hydraulics not restored, HYD Switch - OFF
    • Land as soon as Practical
