Flight controls

The flight control units located in the flight deck of all helicopters are very nearly the same. All helicopters have either one or two of each of the following:
- collective pitch control ,
- throttle grip, cyclic pit ;h control ;
- directional control pedals.
Basically, these units do the same things, regardless of the type of helicopter on which they are installed; however, the operation of the control system varies greatly by helicopter model.
