A turbulence compensated aircraft throttle control system is augmented with switching logic and signal processing to subtantially decrease the magnitude of wind shear-induced airspeed errors and the time required to recover from such airspeed errors. The disclosed arrangements include a throttle controller having a speed control channel that is responsive to airspeed error and a turbulence compensation channel that is responsive to aircraft airspeed and longitudinal inertial acceleration of the aircraft. A signal representative of the wind shear being encountered by the aircraft is derived within the turbulence compensation channel (or from signals provided thereby) and is processed to form a wind shear compensation signal that is coupled into the speed command channel whenever the airspeed error exceeds a predetermined amount. The wind shear compensation signal supplements the airspeed error signal to substantially increase the magnitude of the throttle command signal. In the more detailed disclosed arrangements signal coupling between the speed command channel and the turbulence compensation channel aids in controlling system response to changes in selected airspeed and, during an encounter with wind shear, also couples the wind shear compensation signal back into the turbulence compensation channel to cause even further corrective throttle action.
