Abstract

A control mechanism for a displaceable control member such as an aircraft pilot's "joystick" includes an array of pressure transducers (20) in contact with a pressure plate (22) which in turn is in pivotal connection with the control member (10) operated by the pilot. Adjustable springs (26) bias the pressure plate (22) towards the transducers (20). Pivotal movement of the control member (10) tends to compress the springs (26) and to cause the transducers (20) to generate output signals representative of differential pressure. The signals are then processed by circuitry (34) to provide inputs to flight control computers.
