Chp 9. Flashcards
The term LAND AS SOON AS POSSIBLE is defined as: ________________________
is defined as landing at the nearest suitable landing area (e.g., open field) without delay. (The primary consideration is to ensure the survival of occupants.)
The term LAND AS SOON AS PRACTICABLE is defined as:
________________________
is defined as landing at a suitable landing area. (The primary consideration is the urgency of the emergency.)
The term AUTOROTATE is defined as
________________________
is defined as adjusting the flight controls as necessary to establish an autorotational descent and landing.
The term ESTABLISH SINGLE-ENGINE AIRSPEED is defined as :
________________________
- O________________________
- O________________________
- O________________________
The term EMER ENG SHUTDOWN is defined as:
______________________
- O______________________
- O______________________
- O______________________
The term LOCKOUT is defined as:
______________________
- O______________________
The term LOCKOUT is defined as manual control of engine RPM while bypassing ECU, or DEC/EDECU functions. Bypass of the engine control will be required when % RPM 1 or 2 decreases below normal demand speed due to a malfunction of the ECU/DEC/EDECU.
The term EMER APU START is defined as:
______________________
- O______________________
- O______________________
SINGLE-ENGINE FAILURE.
- ______________________
- O____________________
If continued flight is not possible:
- ______________________
If continued flight is possible:
- LAND AS SOON AS PRACTICABLE.
DUAL-ENGINE FAILURE
ECU/DEC/EDECU LOW SIDE FAILURE.
- ______________________.
If partial powered flight cannot be maintained:
- O____________________.
Maintain % TRQ approximately 10% below other engine.
- LAND AS SOON AS PRACTICABLE.
ECU/DEC/EDECU HIGH SIDE FAILURE.
- _____________________.
- O____________________.
Maintain % TRQ approximately 10% below other engine.
- LAND AS SOON AS PRACTICABLE.
If the affected engine does not respond to ENG POWER CONT lever movement in the range between FLY and IDLE, the HMU may be malfunctioning internally.
If this occurs:
- O____________________.
- O Refer to single-engine failure emergency procedure.
LAND AS SOON AS PRACTICABLE.
% RPM INCREASING/DECREASING (OSCILLATION).
- _____________________.
2O. Slowly retard the ENG POWER CONT lever on the suspected engine.
If the oscillation stops and partial power flight cannot be maintained:
3O. Place that engine in LOCKOUT and manually control the power.
- LAND AS SOON AS PRACTICABLE.
If the oscillation continues:
5O. Place the ENG POWER CONT lever back to FLY and retard the ENG POWER CONT lever of the other engine.
If partial power flight cannot be maintained:
6O.Place the engine in LOCKOUT, manually control the power.
- LAND AS SOON AS PRACTICABLE
% TRQ SPLIT BETWEEN ENGINES 1 AND 2.
- ______________________
- If TGT TEMP of one engine exceeds the limiter 875°C with low power engine above 50% TRQ or 901°C with low power engine below 50% TRQ), retard ENG POWER CONT lever on that engine to reduce TGT TEMP. Retard the ENG POWER CONT lever to maintain torque of the manually controlled engine at approximately 10% below the other engine.
- If TGT TEMP limit on either engine is not exceeded, slowly retard ENG POWER CONT lever on high % TRQ engine and observe % TRQ of low power engine.
- If % TRQ of low power engine increases, ENG POWER CONT lever on high power engine - Retard to maintain % TRQ approximately 10% below other engine (the high power engine has been identified as a high side failure).
- If % TRQ of low power engine does not increase, or % RPM R decreases, ENG POWER CONT lever - Return high power engine to FLY (the low power engine has been identified as a low side failure).
- If additional power is required, low power NG POWER CONT lever, momentarily move to LOCKOUT and adjust to set % TRQ approximately 10% below the other engine.
- LAND AS SOON AS PRACTICABLE
ENGINE COMPRESSOR STALL
An engine compressor stall is normally recognized by a noticeable bang or popping noise and possible aircraft yaw. These responses are normally accompanied by the rapid increase in TGT TEMP and fluctuations in Ng SPEED, % TRQ, and % RPM reading for the affected engine. In the event of a compressor stall:
- ______________________.
2O.____________________ (TGT TEMP should decrease).
3O. ENG POWER CONT lever (affected engine) FLY.
If stall condition recurs:
4O.____________________ (affected engine).
5O. Refer to single engine failure emergency procedure
#1 OIL FLTR BYPASS or #2 OIL FLTR BYPASS CAUTION APPEARS.
