3.3.3.4 The Collective Head

Located on the end of the collective lever, the collective head contains several electrical and a

single mechanical switch;

1. Landing Light switch - The landing light switch is used to turn the spotlights mounted in the

underside of the aircraft’s nose on and off in order to illuminate the ground when landing or

manoeuvring close to the ground, (i.e. when hover-taxiing.) The switch has three

positions. The middle “FWD” position causes the main forward-mounted landing light to

illuminate. The top “BOTH” position causes both the underside lights to be illuminated and

can be used when hovering close to the ground to provide a better view of the surface at

night.

Important note:

If a key is mapped to the landing light toggle binding, repeated pressing of

the button cycles the switch up and down through all positions in turn.

2. Governor RPM Increment / Decrement - The helicopter’s engine governor continually tries

to maintain 100% rotor RPM. Environmental conditions or inaccurate set-up may influence

the efficiency of the governor, in which case the target RPM % can be adjusted up or down

by a small margin with the use of this rocker switch.

Pilot Information: The governor is only active when the engine throttle is fully open and

the rotor RPM has entered the green operating band.

3. Starter button - This button is used to spin the engine’s compressor stage during the

engine start-up procedure. The button must be held down for the starter to continue to

function and should only be released once the engine has reached its self-sustaining

speed whilst fuel is combusting. (Refer to “Start-up Procedure” section for full details of its

operation.)

4. Idle Release latch - The idle release latch is a mechanical device that prevents the throttle

from being closed once it has been opened past the latch point unless the Idle Release

button is depressed. This prevents the pilot from accidentally closing the throttle and
