Abstract
A fuel control system for a gas turbine engine includes series-connected first and second metering valves for providing a metered fuel flow to an engine supply line. A downward failure condition in either valve is detected by a detector which produces a signal representative of such failure. A changeover device operates in response to the failure signal to place the system in a condition in which a sufficient metered fuel flow is maintained via the non-failed valve.
