Abstract
A gas turbine engine fuel control system includes a metering device responsive to an electrical signal for regulating fuel flow from a pump to the engine, a shut-off valve downstream of the metering device and operable by a first servo pressure, a spill valve operable by a second servo pressure for spilling fuel from upstream of the metering device, an electrically operable valve for controlling the first and second servo pressures, and a circuit for supplying electrical signals to the metering device and the electrically operable valve so that during shut down of the system the spill valve and the shut off valve are maintained respectively open and shut before the metering device shuts.
