ABSTRACT:
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.
