Turbulence compensated throttle control system for aircraft having throttle command signal path control means responsive to engine rating control and flare initiation

摘要

Command from engine rating control prevents throttle position from exceeding the value at which the engine operates at its rated power. Flare initiation changes the throttle command signal from a closed loop control signal to a fixed number of degrees per second retard rate, thereby overriding an aft limit switch signal allowing throttles to reach the idle position. A servo feedback arrangement utilizes a tachometer signal and an engine PLA (power level angle) signal to optimize servo performance and overcome undesired control cable characteristics.
