A fuel control apparatus for a gas turbine engine reheat system which includes a plurality of burners has a plurality of variable metering orifices associated with the respective burners and a plurality of servo-responsive throttle valves downstream of the respective orifices. The apparatus includes an arrangement for controlling the servo pressures applied to the throttle valves, this arrangement including a governer driven by the engine and mounted on an internal ring gear. A first valve spool is coupled to the ring gear and is axially movable by the governer. The ring gear includes a coaxial spur gear which meshes with further spur gears forming parts of respective valve spools which control the servo pressures for associated throttle valves.
