Abstract
A mechanical variable authority trim mixer for controlling the flow of fuel to an engine receives a main input from the throttle lever and a second input from a trim actuator motor. The trim mixer combines the inputs to produce a single output operably connected to the fuel metering control of the engine. A programmed cam modifies or neutralizes the effects of the trim input through selected ranges of the main throttle input stroke.
