HOTAS, an acronym of Hands On Throttle-And-Stick, is the name given to the concept of placing buttons and switches on the throttle lever and flight control stick in an aircraft's cockpit, allowing pilots to access vital cockpit functions and fly the aircraft without having to remove their hands from the throttle and flight controls. Application of the concept was pioneered with the Ferranti AIRPASS radar and gunsight control system used by the English Electric Lightning and is widely used on all modern fighter aircraft such as the F-16 Fighting Falcon, the A-10A/A-10C and others.
