Emergency Procedures Flashcards
What are the 2 parts to the air restart caution?
Do not attempt restart if:
- engine malfunction is suspected
- before safe autorotation is established
How to do an air restart
1- mixture off
2- throttle closed
3- starter engaged
4- mixture, move slowly rich while cranking
Minimum rate of descent configuration
*airspeed 55 KIAS
*rotor RPM 90%
*minimum rate of descent is about 1350 ft per minute
Ratio 4:1 or 1 nm per 1500 ft AGL
Maximum glide configuration
*airspeed 90 KIAS
*rotor RPM 90%
*best glide ratio 4.7:1
1 nm per 1300 ft AGL
Power failure above 500 ft AGL
1- lower collective
2- establish glide @ 70 knots
3- adjust collective to catch RPM in the green
4- select landing spot, maneuver into the wind if altitude permits
5- restart may be attempted
6- unable to restart, turn off unnecessary switches and shut off fuel
7- 40 ft AGL begin flare
8- 8 ft AGL apply forward cyclic to level ship and raise collective just before touchdown
Engine fire during start on the ground
1- cranking- continue and attempt to start which would suck flames and excess fuel into engine
2- if engine starts, run @ 60-70% RPM for a short time, shut down and inspect for damage
3- if engine fails to start, shut off fuel and master switch
4- extinguish fire
5- inspect for damage
Hydraulic system failure
1- adjust airspeed and flight condition as desired for comfortable control
2- hydraulic switch- verify on
3- if hydraulics not restored, turn hydraulic switch off
4- land as soon as practical
What does the engine fire warning light indicate?
Indicates possible fire in engine compartment
What does aux fuel pump warning light indicate?
Low aux fuel pump pressure
If no other indication land as soon as practical
If light is accompanied by erratic engine operation, land immediately
What does the fuel filter warning light indicate?
Fuel strainer contamination
If no other indication of a problem, land as soon as practical
If light is accompanied by aux fuel pump warning light or erratic engine operation, land immediately
