Adjustable height control stick assembly for dual control of aircraft includes a single control stick for longitudinal and lateral orientation of the aircraft with the height adjustment allowing for correction of position prior to flight. The stick is connected to appropriate linkages to move the ailerons and elevator of an airplane or the rotor blades of a helicopter. When either the pilot or the copilot is flying the grip for the other is at a different height to that for normal operation. The invention replaces and makes adjustable the grip so that height of the grip of both pilot and copilot are the same as if they were flying and in control of the aircraft.
