Abstract
An electrohydraulic servo system to actuate the power shaft of a fuel control system from the cockpit throttle including electrical devices responsive to the position of the throttle that actuates a hydraulic piston for moving the power shaft together with a backup system that assures a shaft position proportional to the throttle position. This permits the use of electrical lines from the cockpit to the engine rather than mechanical cables and linkages.
