Abstract
A fuel control system for a gas turbine engine comprises a main metering valve and a backup metering valve connected in series. A control circuit supplies demand signals such that, during normal operation, the main metering valve controls fuel flow and the back-up metering valve tracks the main valve but at a position which corresponds to a higher flow.
