ABSTRACT:
A fuel control having an electrically operated metering valve and a manually operated metering valve through which fuel is independently scheduled to an engine. During normal operation, the electrically operated metering valve controls the flow of fuel to the engine in response to an operator input signal. However, should an electrical failure occur, the manually operated metering valve is activated to schedule fuel to the engine. The manually operated metering valve has a pressure responsive member that receives an input signal representative of the discharge pressure of a compressor in the engine to prevent surging during acceleration.
