摘要： A control system for a gas-turbine engine has two parallel control units, either one of which can be switched to supply control signals to the engine in response to input signals, such as from the pilot's control lever and from various sensors. Each unit has a limiter that limits the fuel supply to the engine if the engine speed approaches or exceeds a predetermined maximum. A monitor unit in each control unit detects when the limiter has assumed control of the engine for more than a predetermined time, and switches the system to control by the other control unit. The predetermined engine speed may be different for different settings of the pilot's control lever. The monitor unit in such an arrangement, may receive signals in respect of the acceleration and deceleration of the engine and switch to the other control unit only when the speed is outside the predetermined speed for the pilot lever setting, and when the acceleration or deceleration is not such as to bring the speed back within the predetermined speed.
