Abstract
A power boost mechanism for converting pilot linear throttle input commands to rotary motion and providing amplification of output torque to an engine fuel control and having an output shaft adapted for connection to an engine power lever assembly. An input member is movable in response to a throttle input command and power boost structure responsive to movement of the input member causes rotation of the output shaft. The mechanism further includes feedback structure associated with the output shaft and responsive to movement thereof for returning said power boost structure to a null position independently of said input member, structure automatically enabling direct operation of the output shaft by said input member when the power boost structure is inoperative, and structure responsive to a malfunction in the engine fuel control causing limited rotation of the output shaft without movement of said input member.
