Abstract Fuel Control A reduced fuel flow to a gas turbine engine experiencing impending overspend operating conditions is provided through a line (250) which bypasses the main shutoff valve (70) of the engine's fuel control (20). A transfer valve (260) disposed in the bypass line actuates the shutoff valve in response to such overspend conditions while opening the normally closed bypass line. A flow restictor (275) and the fuel control's main pressure regulating valve (210) combine to maintain the reduced fuel flow at a predetermined valve.
