A gas turbine engine fuel control comprises a speed governor controlling the fuel supply and having a control element movable for increasing and decreasing the set point of engine speed, stop means for preventing the movement, when this is in the sense to increase the speed, beyond a position corresponding to a predetermined maximum temperature at a particular location in the flow path of the engine working fluid, and means for sensing the engine temperature at that location and, when the sensed temperature rises above a certain value, acting to advance the stop means to stop the element short of the said position. The fuel supply from a fuel pump 12 to a gas turbine engine is controlled in accordance with engine speed by a control unit 6, the speed being selected by an arm 13 actuated by a selector lever 15. The maximum speed and therefore the maximum temperature in a free power turbine downstream of the engine or in a jet pipe, is set by a stop lever 6 which limits the movement of the arm 13, and is urged against a stop 20 by a spring 22. Compressor discharge pressure is applied via a line 24 directly to a chamber 26 at one side of a piston 17 and through a variable restrictor 25 to a chamber 27 on the other side. If the exhaust gas temperature exceeds a certain value, a temperature senser 18 opens a valve 28 to vent the chamber 27, whereupon the piston 17 moves the stop lever 16 towards a stop 19, thereby reducing the maximum speed which can be selected by the arm 13.
