Emergencies Flashcards
Define:
Land as soon as possible
Land without delay at nearest suitable area at which a safe approach can be reasonably assured
When does engine out light come on
55 % N1 +- 3
Define:
Land as soon as practical
Landing site rand duration o flight are at discretion of pilot
What is the fault and remedy related to a “trans temp” warning light.
Main transmission is at or above red line 110*C. Reducing power will help alleviate the condition. Check transmission oil pressure. Land as soon as possible.
What is the fault and remedy related to a “trans press” warning light
Main transmission pressure is below minimum. Landing should be made as soon as possible.
What is the unusable fuel with both fuel boost pumps inop?
10USG
What is the fault and remedy related to a “fuel pump” warning light
One or both fuel pumps is inoperative. Descend to below 6000 feet pressure altitude I flight permits. Land as soon as practical
What is the fault an remedy indicated by a “fuel filter” light
Engine fuel filter clogged, land as soon as practical. Clean before next flight
What is the fault and remedy related to a “A/F fuel filter” warning light
Airframe fuel filter clogged. Land as soon as practical. Clean before next flight.
What is the fault and remedy related to a “fuel low” warning light.
Approximately 20 gallons of fuel remaining. Land as soon as practical
What is indicated by a “eng out” warning light and remedy
Engine power failure. Reduce pitch immediately and investigate power failure.
What is the fault and remedy related to “eng chip” warning light
Metallic particles in engine oil. Land as soon as possible
What is the fault and remedy related to a “t/R chip” warning light
Metal particles in tail rotor gear box oil. Land as soon as possible.
What is the fault and remedy related to “trans chip”
Metal particles in transmission oil. Land as soon as possible
What is the fault and remedy related to a “rotor low rpm” warning light
Rotor RPM is below normal. Reduce collective pitch and check that throttle is full open
What is the rotor RPM range required to maintain rotor ROM during an engine failure
90%-107%
What is the desired airspeed range for autorotation
58-69MPH
What is the max airspeed for steady autorotation
115 mph
What could result during autorotations performed above 115MPH
Could result in high rates of descent and low rotor speed.
What are the steps to respond to a complete loss of tail rotor thrust
Roll throttle flight idle enter auto rotation and maintian minimum airspeed to 58MPH during descent
What to do in the event of a fuel control or governor failure
Control power with throttle if engine over speeds
Maintain RPM with collective pitch If engine under speeds
Establish autorotative glide if power is very low or if engine must be shut down
Steps to take as a result of hydraulic system failure
Reduce airspeed to 70-80MPH IAS
Check hydraulic switch is on
Hyd boost circuit breaker-out if power not restored “in”
Land as soon as practical and investigate
Run-on landing 12-17MPH recommended
Electrical power failure
Cycle generator switch-if power not restored “off”
All electrical equipment “off”, on as needed
Reduce altitude below 6000feet(fuel boost pumps)
Helicopter fuel system failure-both boost pumps
Descend below 6000 feet land as soon as practical. Unusable fuel 10 gallons
Engine fire during flight
Throttle-closed
Immediately enter autorotation
Fuel valve-OFF
battery switch-off
generator switch-off
Execute autorotational descent and landing
Do not restart until maintenance has been performed
Engine air start
-when believed to be a mechanical problem do not attempt restart
Maintain autorotation glide
Rotor rpm 90-107
Airspeed 58-69MPH
Generator-off
Normal start
Do not attempt above 12,000feet as TOT rises to fast to control
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
