There is usually a twist throttle on the collective for a single engine helicopter. On twin engine helicopters, does the twist throttle control it for both engines, or just for one?


1 Answer 1


Most employ separate throttles, either twist-type, on the collective or levers in an overhead quadrant.

Bell products use duel collective mounted, twist type throttles, in series. Sikorsky uses overhead levers. French SA > AS > Eurocopter > Airbus > Leonardo use levers overhead. Agusta uses overhead levers.

  • $\begingroup$ @Walker, are there two separate twist type throttles, or just one (that controls both engines) on Bell helicopters? $\endgroup$

  • $\begingroup$ @jeff0000 Yup. Sorry. Bells use two separate twist throttles, in series (See Edit). I don't remember which engine corresponds to the more forward twist-grip vs the more aft twist-grip. $\endgroup$
