A linkage system is disclosed adapted to be connected between a pilot's input lever and an engine power output lever. The linkage system is operative to vary the displacement ratio characteristics between the input and output levers. More specifically, during the first portion of input lever stroke, wherein shaft horsepower is raised from a ground idle speed to flight speed, the output lever is displaced an amount greater than the amount the input lever is displaced. In contrast, during the second portion of the stroke, corresponding to the upper range of shaft horsepower used in flight, a fixed amount of displacement of the input lever results in a smaller displacement of the output lever. By this arrangement, the control of the aircraft in flight is facilitated.
