shutting down the engine. When the throttle is advanced past the latch the button “pops

out.” The pilot has to push the button back in again to be able to close the throttle below

the latch point.

Pilot Information: The latch operates at approximately 6% of the throttle axis movement.

Note that this does not equate to 6% of the total fuel flow. Different Fuel Control Units

(FCUs) meter fuel differently depending on how far the throttle is opened. (See section

“Fuel Control Units” within the Start-Up Procedures section for full details.)

5. Engine Throttle - As described in the “Flight Controls” section above, this twist-grip

controls the engine throttle. (Refer to the “Start-Up Procedures” section for full details on

its operation.)

Pilot Information: The throttle opens to the left. This is due to historical reasons where

helicopters without governors required the throttle to be increased to maintain rotor RPM as

the collective lever was raised. It is more comfortable to rotate your wrist that way whilst

raising your arm. (Picture yourself holding the collective. Twist your wrist so your knuckles

move away from your body as you raise your arm.)

The 2D cockpit’s collective lever’s throttle can be operated with the mouse.

Moving the mouse pointer onto zone A, you will see that the pointer changes to a hand

with a ‘+‘ on it. Clicking here with the left button increases the throttle by 0.5%. Right

clicking here opens it fully to 100%.

Moving the mouse into zone B, the pointer changes to just a hand. Clicking anywhere in

here will open the throttle to a proportional amount from the right hand edge of zone B. i.e.

clicking at point ‘i’ will open it to 33%, point ‘ii” will open it to 66%. Care must be taken

during the start-up procedure if using the mouse that the throttle is not opened too far too

early. Note that you do not “drag” the mouse, but click it within zone B. (Refer to the “Start-

Up Procedures” section later for full details of the throttle usage during engine starting.)

Moving the mouse pointer onto zone C, you will see that the pointer changes to a hand

with a ‘-‘ on it. Clicking here with the left button decreases the throttle by 0.5%. Right

clicking here closes it fully to 0%. However, the idle release latch will prevent the throttle

from closing below 6% until it is clicked, (or triggered by a mapped key or joystick button.)

At that point the throttle will close to whatever mouse-driven setting was applied.

Important note: If you intend to use the mouse to control the throttle, it is strongly

suggested that you get acquainted with the mouse actions and practice whilst the engine is
