Abstract
A fuel control system for a gas turbine aero engine comprises a first metering valve 22 which is controlled by a feed back loop 43 in flow series with a manually operated metering valve 34. A pressure drop regulator 31, 39 regulates the pressure drop across the series connected valves 22, 34. In this way response of the control system is directly influenced by movement of the manual valve 34 and the automatic valve 22 stabilizes the fuel flow rate in response to monitored operating parameters of the engine.
