DEFINITION OF EMERGENCY TERMS
Land as Soon as Possible
DEFINITION OF EMERGENCY TERMS
The term LAND AS SOON AS POSSIBLE 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.)
DEFINITION OF EMERGENCY TERMS
LAND AS SOON AS PRACTICABLE
DEFINITION OF EMERGENCY TERMS
The term LAND AS SOON AS PRACTICABLE is
defined as landing at a suitable landing area. (The
primary consideration is the urgency of the emergency.)
DEFINITION OF EMERGENCY TERMS
Autorotate
DEFINITION OF EMERGENCY TERMS
The term AUTOROTATE is defined as adjusting the
flight controls as necessary to establish an autorotational descent and landing.
DEFINITION OF EMERGENCY TERMS
ESTABLISH SINGLE-ENGINE AIRSPEED
DEFINITION OF EMERGENCY TERMS
The term ESTABLISH SINGLE-ENGINE AIRSPEED
is defined as maneuvering the aircraft to an appropriate
airspeed that will allow for continued flight under
partial power conditions to a suitable recovery area.
ESTABLISH SINGLE-ENGINE AIRSPEED -EP
ESTABLISH SINGLE-ENGINE AIRSPEED 1. Cyclic - Adjust as required. 2. Collective - Adjust as required to maintain % RPM R within normal operating range. 3. Establish appropriate airspeed.
DEFINITION OF EMERGENCY TERMS
EMERGENCY ENGINE SHUTDOWN
DEFINITION OF EMERGENCY TERMS
The term EMER ENG SHUTDOWN is defined as engine shutdown without delay.
EMERGENCY ENGINE SHUTDOWN -EP
EMERGENCY ENGINE SHUTDOWN
- ENG POWER CONT lever(s) - OFF.
- ENG FUEL SYS selector(s) - OFF.
- FUEL BOOST PUMP CONTROL switch(es) - OFF.
DEFINITION OF EMERGENCY TERMS
LOCKOUT
DEFINITION OF EMERGENCY TERMS
The term LOCKOUT is defined as manual control of engine RPM while bypassing DEC/EDECU functions.
LOCKOUT WARNING
Going to ECU/DEC/EDECU LOCKOUT to obtain additional power does not remove Maximum Fuel Flow or Ng limits. % RPM R will decrease below normal operating range if Maximum Fuel Flow or Ng limits are exceeded.
LOCKOUT Caution
When engine is controlled with ENG POWER CONT lever in LOCKOUT, engine response is much faster and TGT limiting system is inoperative. Care must be taken not to exceed TGT limits and keeping % RPM R and % RPM 1 and 2 in operating range.
LOCKOUT -EP
LOCKOUT
ENG POWER CONT lever - Pull down and advance
full forward while maintaining downward pressure, then
adjust to set % RPM R as required.
DEFINITION OF EMERGENCY TERMS
Emergency APU Start
DEFINITION OF EMERGENCY TERMS
The term EMER APU START is defined as APU start to accomplish an emergency procedure.
SINGLE-ENGINE FAILURE -EP
SINGLE-ENGINE FAILURE
- ESTABLISH SINGLE-ENGINE AIRSPEED.
- External cargo/stores - Jettison (if required).If continued flight is not possible:
- LAND AS SOON AS POSSIBLE.If continued flight is possible:
- LAND AS SOON AS PRACTICABLE.
SINGLE/DUAL-ENGINE FAILURE.
WARNING
SINGLE/DUAL-ENGINE FAILURE.
WARNING
Do not respond to ENG OUT warning and audio until checking TGT TEMP, Ng SPEED, and % RPM 1 and 2.
DUAL-ENGINE FAILURE - EP
DUAL-ENGINE FAILURE - EP
1. AUTOROTATE
AUTOROTATE Deceleration Height Above Touchdown
AUTOROTATE Deceleration Height Above Touchdown
At 50 to 75 feet AGL, use aft cyclic to decelerate. T
ECU/DEC/EDECU LOW SIDE FAILURE.
ECU/DEC/EDECU LOW SIDE FAILURE.
1. ESTABLISH SINGLE-ENGINE AIRSPEED.
If partial powered flight cannot be maintained:
- ENG POWER CONT lever (low % TRQ/
TGT TEMP engine) - LOCKOUT. Maintain % TRQ
approximately 10% below other engine. - LAND AS SOON AS PRACTICABLE.
ECU/DEC/EDECU HIGH SIDE FAILURE.
ECU/DEC/EDECU HIGH SIDE FAILURE.
If an engine control unit fails to the high side:
- ESTABLISH SINGLE-ENGINE AIRSPEED.
- ENG POWER CONT lever (high % TRQ/ TGT TEMP engine) - Retard. 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:
- Perform EMER ENG SHUTDOWN (affected engine).
- Refer to single-engine failure emergency procedure.
% RPM INCREASING/DECREASING (OSCILLATION).
% RPM INCREASING/DECREASING (OSCILLATION).
1. ESTABLISH SINGLE-ENGINE AIRSPEED.
All other Steps are not underlined
ENGINE COMPRESSOR STALL.
ENGINE COMPRESSOR STALL.
- ESTABLISH SINGLE-ENGINE AIRSPEED.
If condition persists:
- ENG POWER CONT lever (affected engine) - Retard (TGT TEMP should decrease).
- ENG POWER CONT lever (affected engine) - FLY.
If stall condition recurs:
- EMER ENG SHUTDOWN (affected engine).
- Refer to single-engine failure emergency procedure.
