Question 1

Ditching Power-On

Answer 1

If ditching becomes necessary, with power available accomplish an approach to a hover above the water and:

    1. Doors- OPEN
    2. Crew (except pilot) and passengers- Exit
    3. Hover a safe distance away from personnel.
    4. Autorotate. Apply all remaining collective as the helicopter enters the water. Maintain a level attitude as the helicopter enters the water. Maintain a level attitude as the helicopter sinks and begins to roll, then apply cyclic in direction of the roll.
    6. Pilot- exit when the main rotor stops.

Question 2

Ditching- Power Off

Answer 2

If an engine failure occurs over water and ditching is imminent, Accomplish engine failure emergency procedures and proceed as follows:

    1. Autorotate. Decelerate to minimum forward speed as the helicopter nears the water. Apply all remaining collective as the helicopter enters the water. Maintain a level attitude as the helicopter sinks and until it begins to roll, then apply cyclic in the direction of the roll.
    2. Doors- OPEN
    3. Crew and passengers- Exit when the main rotor stops.

Question 3

Warning Light (Red) Segments

Answer 3

ENG OUT
Engine power failure (N1) less than 55% +/- 3. Attempt restart if time and conditions permit.

BATTERY HOT
Land as soon as possible.

Question 4

Caution Light (Amber) Segments

Answer 4

ROTOR LOW RPM
Rotor RPM is below normal (approximately 90%). Reduce collective pitch and ensure throttle full open.

TRANS OIL PRESS
Main transmission pressure is below minimum. Check gauge. Land as soon as possible.

TRANS OIL TEMP
Main transmission oil temperature is above 110*C, check gauge. Reducing power may help alleviate the condition. Check transmission oil pressure. Land as soon as possible.

BATTERY TEMP
Land as soon as possible

ENGINE CHIP
Metallic particles in engine oil. Land as soon as possible.

TRANS CHIP
Metallic particles in transmission oil. Land as soon as possible.

T/R CHIP
Metallic particles in tail rotor gearbox oil. Land as soon as possible.

A/F FUEL FILTER
Airframe fuel filter impending bypass. Land as soon as practicable. Clean before next flight.

FUEL PUMP
See emergency procedure

MAIN GEN FAIL
See emergency procedure

HEATER OVERTEMP
Indicates excessive heat (220*F) in HEATER switch- OFF. If light does not extinguish: land as soon as practicable.

FUEL LOW
Plan landing, approximately 12 gallons of fuel remains.

BATTERY RELAY
Illumination is normal during engine starting. All other times when BATT Switch is in BATT, continued illumination indicates a fault in battery relay or protection circuits. With the BATTERY RELAY light illuminated IMC flight is prohibited. If light remains illuminated after BATT switch is turned OFF relay has failed in closed position. Manually disconnect battery.

LOW INLET PRESSURE
See emergency procedure

SPARE
Unknown malfunction: land as soon as possible.

Question 5

Advisory Light (GREEN) Segments

Answer 5

NOTE
When Anti Ice system is on, TOT will rise for same power setting.

ENGINE ANTI ICE
ENGINE ANTI ICING switch is in ON position. Verify switch position is as desired.

ANT TUNE
Wait until Light extinguishes before talking.
