A control lever assembly for a tilt-rotor aircraft, comprises at least one control lever which is movable relative to a control lever support. The control lever support has a rotational position that varies in correspondence with the tilt of the rotor of the aircraft. For example, the control lever support is movable by an actuator between a first position, in the airplane mode of the aircraft, in which the control lever moves substantially horizontally and a second position, in the helicopter mode of the aircraft, in which the control lever moves substantially vertically.
