Study Notes
###Autorotation
- Perform a hovering autorotation at approximately 5 to 10 ft above touchdown by pressing the CHOP button or setting POWER levers to OFF
- Reduce collective to compromise between rate of turn and rate of descent
- Minimize rate of descent (10 to 20 ft above touchdown)
- Set POWER levers to OFF (5 to 10 feet above touchdown)
###Main Transmission Input Drive Clutch Failure
- Failure may occur during engine start or when an engine POWER lever is advanced
- Indications include:
- Erratic torque indication on affected engine
- Complete loss of torque indication on affected engine
- NP of affected engine exceeding NR
- Response:
- EMERG HYD button — Press ON
- Collective — Reduce
- Wing Stores Jettison — As appropriate
- Minimize Rate of Descent
- POWER levers — OFF (5 to 10 feet above touchdown)
###Tail Rotor Fixed Pitch Malfunction
- Failure may be evidenced by slow, intermittent, or no response to pedal input or no pedal movement
- Left or right yaw may be apparent
- Response:
- AUTOROTATE — Apply full collective to decay rotor RPM as helicopter settles
- Exit when main rotor has stopped
###Flight Control Malfunctions
- Failure of components may be indicated through varying degrees of feedback, binding, resistance, sloppiness, or abnormal control responses
- Response:
- LAND AS SOON AS POSSIBLE
- APU — ON
- EMERG ENG(S) SHUTDOWN
###Main Rotor Components Failure
- Imminent failure may be indicated by a sudden increase in main rotor vibration and/or unusual noise
- Response:
- A minimum of 100 KTAS during a shallow approach to a roll on landing should be maintained until approximately 10 to 20 ft above the touchdown point
- Begin a gradual deceleration to arrive at approximately 5 to 10 ft above touchdown
###Single Engine Failure – Low Altitude/Low Airspeed and Cruise
- Voice message will announce ENGINE 1 OUT or ENGINE 2 OUT
- Response:
- Airspeed — Adjust as appropriate
- Wing Stores Jettison — As appropriate
- LAND AS SOON AS PRACTICABLE
###Loss of Tail Rotor Thrust
- May result in extreme yaw angles and uncontrolled rotation to the right
- Response:
- Immediate collective pitch reduction to reduce yaw rate
- Jettison wing stores to reduce gross weight, drag, and improve airflow over the vertical fin
- If possible, increase airspeed to streamline the helicopter and aid forward acceleration
Emergency Exit and Entrance
- Identification of malfunctioning engine is crucial to avoid shutting down the wrong engine in flight.
- Activation of canopy removal system when combustible fuel/vapors are present can result in an explosion/fire.
- If TGT rises above 540° C or shows evidence of combustion, place ENG START switch in IGN ORIDE position and motor engine until TGT decreases below 540° C.
- Emergency engine shutdown (EMERG ENG SHUTDOWN) is defined as engine shutdown without delay.
Emergency Engine Shutdown
- EMERG ENG SHUTDOWN (affected engine only): check NG is less than 10%.
- EMERG ENG(S) SHUTDOWN (both engines simultaneously): if APU is running, accomplish APU shutdown prior to evacuating the aircraft.
Fires
- If an engine fire occurs in flight, a voice message will announce ENGINE 1 (or) ENGINE 2 FIRE.
- Engine must be controlled manually to ensure it does not exceed operating limits.
Engine Malfunctions
- It's possible for the T700-GE-701D engine to self-ignite or auto re-ignite following an NP overspeed and shutdown event if TGT is high enough.
- Self-ignition differs from auto re-ignition in that it is uncommanded and not a normal function of the AH-64E.
Flight Control Malfunctions
- Failure of components within the flight control system may be indicated through varying degrees of feedback, binding, resistance, sloppiness, or abnormal control responses.
- BUCS FAIL caution may indicate a failure within the system or a mistrack between the crew station controls.
- Imminent failure of the main rotor components may be indicated by a sudden increase in main rotor vibration and/or unusual noise.
Electrical System Malfunctions
- Dual TRU failure (Transformer Rectifier 1 and Transformer Rectifier 2) will result in a number of Cautions and Advisories displayed on the EUFD, including BUCS FAIL and FMC FAIL.
- DC services will be lost, except those provided by the battery, and charging of the battery will no longer be conducted.
