UH-60M EP Ch6 Flashcards
SINGLE-ENGINE FAILURE.
SINGLE-ENGINE FAILURE.
1. Collective — Adjust to maintain NR.
2. External cargo/stores — Jettison (if required).
3. Establish single-engine airspeed.
If continued flight is not possible:
4. LAND AS SOON AS POSSIBLE.
If continued flight is possible:
- LAND AS SOON AS PRACTICABLE.
DUAL-ENGINE FAILURE.
AUTOROTATE.
DECREASING NR.
1. Collective — Adjust to control NR.
1.1. Establish single-engine airspeed.
If single engine flight cannot be achieved or maintained:
2. ENG POWER CONT lever (low Q/TGT TEMP engine) — LOCKOUT. Maintain Q approximately 10% below other engine.
- LAND AS SOON AS PRACTICABLE.
INCREASING NR.
1. ENG POWER CONT lever (high Q/TGT engine) — Retard. Maintain Q 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:
3. Establish single engine airspeed.
- Perform EMER ENG SHUTDOWN (affected
engine) . - Refer to single-engine failure emergency
procedure.
ENGINE COMPRESSOR STALL.
1. Establish single engine airspeed.
2. Collective — Reduce.
If condition persists:
3. ENG POWER CONT lever (affected engine) — Retard (TGT 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.
ENG 1 OIL BYPASS OR ENG 2 OIL BYPASS CAUTION APPEARS.
1. Establish single engine airspeed.
- ENG POWER CONT lever — Retard.
- LAND AS SOON AS PRACTICABLE.
CHIP ENG 1 OR CHIP ENG 2, ENG 1 OIL PRESS OR ENG 2 OIL PRESS, ENG 1 OIL HOT OR ENG 2 OIL HOT CAUTION APPEARS.
1. Establish single engine airspeed.
- ENG POWER CONT lever (affected engine) — Retard (to reduce torque).
If oil pressure is below minimum limits or if oil
temperature remains above maximum limits:
- EMER ENG SHUTDOWN (affected engine).
- Refer to single engine failure emergency procedure.
ENGINE HIGH-SPEED SHAFT FAILURE.
1. Establish single engine airspeed.
2. Collective — Adjust.
3. EMER ENG SHUTDOWN (affected engine).
Do not attempt to restart.
- Refer to single-engine failure emergency
procedure.
LIGHTNING STRIKE.
1. ENG POWER CONT levers — Adjust (as required to control NP and NR).
2. LAND AS SOON AS POSSIBLE.
LOSS OF TAIL ROTOR THRUST IN CRUISE FLIGHT.
1. Airspeed — Adjust to 80 KIAS or above.
2. AUTOROTATE — Maintain airspeed at or above 80 KIAS.
3. ENG POWER CONT levers — OFF (during deceleration when intended point of landing is assured).
LOSS OF TAIL ROTOR THRUST OR T/R QUAD FAIL CAUTION APPEARS WITH LOSS OF CONTROL AT LOW AIRSPEED/HOVER (RIGHT ROTATION).
1. Collective — Reduce.
2. ENG POWER CONT levers — OFF (5 to 10 feet above touchdown).
T/R QUAD FAIL CAUTION APPEARS IN CRUISE FLIGHT.
1. Collective — Adjust to determine controllability (Fixed Right or Left).
- LAND AS SOON AS PRACTICABLE
LOSS OF CONTROL AT LOW AIRSPEED/HOVER OR T/R QUAD FAIL CAUTION APPEARS (LEFT ROTATION).
1. ENG POWER CONT lever(s) — Retard to decrease NR below 100% and begin a partial power descent.
2. Collective — Adjust to preserve NR.
3. ENG POWER CONT levers — OFF (5 to 10 feet above touchdown).
4. Collective — Adjust for landing.
PEDAL BIND/RESTRICTION OR DRIVE WITH NO ACCOMPANYING CAUTION.
1. Apply pedal force to oppose the drive.
- Check other pedals for proper operation.
- TAIL SERVO switch — BACKUP.
If normal control authority is not restored:
- TAIL SERVO switch — NORMAL.
- SAS/BOOST switch — OFF.
If normal control forces are not restored:
- SAS/BOOST switch — ON.
- Collective — Adjust to determine controllability for landing.
- LAND AS SOON AS PRACTICABLE.
T/R SERVO 1 FAIL CAUTION APPEARS AND BACK UP PUMP ON ADVISORY DOES NOT APPEAR OR T/R SERVO 2 ON ADVISORY DOES NOT APPEAR.
Automatic switch over did not take place.
1. TAIL SERVO switch — BACKUP.
- BACKUP HYD PUMP switch — ON.
- LAND AS SOON AS PRACTICABLE.
MAIN XMSN PRESS CAUTION APPEARS/MAIN XMSN OIL HOT CAUTION APPEARS.
1. LAND AS SOON AS POSSIBLE.
If time permits:
- Slow to 80 KIAS.
- EMER APU START.
- GENERATORS NO. 1 and NO. 2 switches — OFF.
