LAND AS SOON AS POSSIBLE

Land without delay at the nearest area that minimises or prevents damage additional to that of the initial emergency.
The primary consideration is to ensure the survival of the occupants.

1

LAND AS SOON AS PRACTICABLE

Land at the nearest suitable airfield/heliport/unit operating area.

2

AUTOROTATE

1. Collective – adjust to maintain RPMR.
2. Cyclic/Pedals – adjust as required.
3. Airspeed – adjust as required.

3

EMERGENCY ENGINE SHUTDOWN

Defined as engine shutdown without delay.

Engine shutdown in flight is usually not an immediate action item unless a fire exists.

Before attempting an engine shutdown, identify the affected engine by checking ENG OUT warnings, %RPM, %TRQ, ENG OIL PRESS, TGT TEMP and Ng SPEED.

1. ENG PCL(s) – OFF.
2. ENG FUEL SYS selector(s) – OFF.
3. FUEL BOOST PUMP CONTROL switches – OFF.

If TGT is above 538ºC after shutdown:
4. AIR SOURCE HEAT/START switches – as required.
5. ENGINE IGNITION switch – OFF.
6. Starter Button – press to motor engine for 30 seconds or until TGT TEMP decreases below 538ºC.

DOUBLE ENGINE FAILURE (Info)

Autorotative Descent:
Recommended configuration for autorotation is 100% RPMR and 80 KIAS which is slightly higher than the airspeed for minimum ROD for all gross weights.

A flare before landing initiated below 80 KIAS will have very little effect on ROD.

Adjusting the cyclic and collective control to maintain 100% RPMR and 110 KIAS will result in achieving the
maximum glide distance.

8

Double Engine Failure (Hovering or Hover Taxi)

2x WARNINGS

2. Tail Rotor Pedals – adjust as required.
3. External load – jettison (if necessary).
