Emergency Procedures Flashcards
Engine Failure above 450 ft
Lower collective pitch.
Enter Autorotation.
Establish steady glide of 52kts (IAS).
At 50ft initiate a flare.
At 10 feet, coordinate collective pitch with forward movement of cyclic stick to level aircraft and cushion landing.
Avoid rapid lowering of collective pitch or use of aft cyclic during initial ground contact or slide.
Engine Failure below 7 ft
Apply right pedal to prevent excessive yawing and right stick to minimize drift
Apply collective pitch as necessary in order to cushion landing.
Ditching Power Off
Perform autorotation Lower collective pitch Apply sideward stick after contact with water Release seat belt and harness Open both doors and exit helicopter
Ditching - Power On
Descend to hovering altitude over water
Unlatch doors
Passengers exit the aircraft
Fly to a safe distance away from passengers
Turn battery and alternator switches OFF
Close twist grip to idle position
Allow aircraft to settle in a level attitude, apply full collective
When aircraft begins to roll, reduce collective to full down.
Release seat belt and shoulder harness
When rotor blades have stopped turning, clear aircraft as quickly as possible.
Transmission Warning/Caution Indicators - Main Rotor
M/R XMSN TEMP/PRESS light comes on when transmission oil pressure drops below 2.5 psi or temperature exceeds 235 degrees F.
LAND ASAP
Transmission Warning/Caution Indicators - Main Rotor
Optional Chip Detector Caution Indicator:
Amber caution light (M/R XMSN CHIPS) on the instrument panel comes on to indicate possible deterioration of components within the main rotor transmission.
LAND ASAP
Transmission Warning/Caution Indicators - TAIL Rotor
Chip Detector Caution Indicator
An amber caution light (T/R XMSN CHIPS) on the instrument panel comes on to indicate possible deterioration of components within the tail rotor transmission.
LAND ASAP
Fuel Low Caution Indicator
Fuel Low light comes on when approximately 1 gallon of useable fuel remains in the tank.
LAND IMMEDIATELY
Clutch Warning Light
When the warning light is illuminated whenever the clutch is not fully engaged.
Be prepared for autorotation
Land ASAP
TAIL ROTOR FAILURE:
Indicated by uncontrollable yawing to the right.
Reduce power by lowering collective
Adjust airspeed to 50 - 60 knots
Use lateral cyclic in combination with collective pitch to limit side slip to a reasonable angle.
If conditions permit, place the twist-grip in IDLE position once landing area is selected and perform a normal autorotation.
Plane to land with little to no forward speed.
Loss of tail rotor at a Hover
Place twist grip at idle and perform hovering autorotation.
Air Restart
Establish Autorotation. Pick a landing spot. Mixture Idle Cutoff Crack throttle 1/2” Engage starter Push mixture full rich
Fire on the ground
Mixture idle CUTOFF Fuel valve - CLOSE Battery - OFF Alternator - OFF Exit aircraft with extinguisher Extinguish fire
Fire at cruise/altitude (Power on)
Maintain airspeed & Rotor RPM (Be prepared to perform autorotation at any time)
Immediately perform power-on landing to suitable area
If time permits:
A) battery -OFF
B) Alternator - OFF
C) Cabin Heater - OFF
UPON LANDING:
Throttle - CLOSED
Mixture - IDLE CUTOFF
Fuel Valve - Close
Exit aircraft with extinguisher and extinguish fire.
Fire at cruise/altitude (Power OFF)
Enter Autorotation If time permits: A) Mixture -Idle CUTOFF B) FUEL Valve -CLOSED C) Battery - OFF D) Alternator - OFF E) Cabin heater - OFF
UPON LANDING: Exit aircraft with extinguisher and extinguish fire
