The fuel flow for a turboprop or turboshaft engine is provided by a plurality of parallel circuits each of which supplies a portion of the fuel to the engine with different valves controlling the flow through each of the separate circuits. In the turboprop engine there is imposed on the parallel flow circuits a sensing device that determines the pressures in certain of the circuits and selects the appropriate pressure for signalling a pressure regulating valve whereby to vary the pressure drop through the fuel control. |
