Abstract
According to the present invention, a fuel control has an electronic primary control for scheduling a flow of fuel to an engine in a primary mode and hydromechanical secondary control for scheduling the flow of fuel to the engine in a backup mode. The fuel control also has a tracking piston and link whose position is responsive to the HMU during the operation of the electronic primary control. The tracking piston and link effectively changes the power lever angle sensed by the HMU so that in the event of a transfer of control from the electronic primary control to the HMU, changes in the scheduled fuel flow to the engine are minimized.
