Emergency Procedures Flashcards
Land as soon as possible
Land without delay at nearest suitable area(i.e. open field) at which a safe approach and landing is reasonably assured.
Land as soon as practical
Landing site and duration of flight are at discretion of pilot. Extended flight beyond nearest approved landing area is not recommended.
Warning light: trans temp
Main transmission oil temperature is at or above red line. Reducing power will help alleviate the condition. Check transmission oil pressure. Land as soon as possible.
Warning light: trans press
Main transmission pressure is below minimum. Landing should be made as soon as possible.
Warning light: fuel pump
One or both fuel boost pumps is inoperative. Descend to below 6000ft pressure altitude if flight permits. Land as soon as practical.
Warning light: fuel filter
Engine fuel filter clogged, land as soon as practical. Clean before next flight.
Warning light: a/f fuel filter
Airframe fuel filter clogged. Land as soon as practical. Clean before next flight.
Warning light: fuel low (if installed)
Approximately 20 gallons of fuel remaining. Land as soon as practical.
Warning light: Eng out
Engine power failure. Reduce pitch immediately and investigate power failure.
Warning light: eng chip
Metallic practicals in engine oil. Land as soon as possible.
Warning light: t/r chip
Metal partials in tail rotor gearbox oil. Land as soon as possible.
Warning light: trans chip
Metal particles in transmission oil. Land as soon as possible.
Warning light: rotor low rpm
Rotor rpm is below normal. Reduce collective pitch and check that throttle is full open.
Complete loss of tail rotor thrust
Reduce throttle to flight idle, immediately enter autorotation and maintain a minimum airspeed of 58mph during the descent.
Tail rotor fixed pitch failure
Depending on the pitch position of the tail rotor, at the time of failure, engine power and airspeed should be adjusted to minimize yawing.
Fuel control and/or governor failure
Engine fuel control and/or governor failure will be apparent by a change of power or rpm. There is no manual fuel control on the engine. Control power with the throttle if engine overspreeds.
Maintain rpm with collective pitch if engine underspeeds.
Establish autorotative glide if power is very low or if engine must be shut down.
Hydraulic system failure
Reduce airspeed to 70 to 80 mph
Hyd boost circuit breaker OUT; if power is not restored IN
Control boost or hydraulic system switch ON; if power is not restored OFF
Land as soon as practical and investigate.
A run-on landing at 12 to 17 mph is recommended. Maintain airspeed above translational lift speed for best control at touchdown.
Electrical power failure
Cycle generator switch; if power is not restored OFF
Non critical electrical equipment OFF
Required electrical equipment ON as needed
Engine fire during starting or shutdown
Starter- continue to motor the engine
Throttle- full closed
Fuel valve switch- off
IGN ENG circuit breaker- out
Complete shutdown
Engine fire during flight
Throttle- close
Immediately enter autorotation
Fuel valve switch- off
Battery switch- off
Generator switch- off
Execute autorotation
