Abstract
An automatic throttle system operable during all flight regimes includes automatic gain control apparatus for minimizing changes in engine thrust during the cruise mode caused by air mass turbulence and provides desirable response to commanded changes in air speed or flight path while maintaining desirable response to large magnitude wind shears. The gain of the air speed error signal is controlled as a function of Mach or true air speed and the gain of the throttle rate command signal normally controlling the engine throttle servo motor is controlled as a function of the commanded change in air speed, the air speed error, the aircraft's Mach or true air speed, and altitude rate by a real time logical control system.
