An aircraft threat monitoring system has several sensors responsive to a potential threat external to the aircraft, such as a radar warning receiver 2, a radar sensor 3, a missile approach warning receiver 4, a forward-looking infrared detector 5 and an electro-optic sensor 6. Each sensor has a respective inference processor 21 to 61 the outputs of which are supplied to a groundspace map manager 11 and an airspace map manager 12. The map managers 11 and 12 collate the processor outputs to derive a threat output signal which is supplied to a planner 7 programmed with tactical route information. The map managers 11 and 12 also control operation of the sensors 2 to 6 such as by modifying their sensitivity, scan or frequency in accordance with the output from other sensors to provide more information about the detected threat or to reduce the ability of a detected missile to home on the aircraft. <IMAGE>
