[0002] The fuel booster pump control system is an important system to ensure the flight of the aircraft. Its function is to ensure the normal operation of the fuel supply system on the aircraft, and to improve the flight safety of the aircraft through automatic switching between the main fuel pump and the emergency pump. Most of the fuel booster pump alarm systems used are warning lights and warning lights, and an additional warning light box needs to be made, and the use of attention lights and warning lights increases the failure rate of the equipment, which brings inconvenience to the maintenance of the ground crew and takes up dashboard space
