Fault detection, analysis and prevention of aircraft electrical circuit

Aircraft electrical circuits are used to complete the transmission of electrical energy and electrical control signals between airborne equipment. The aircraft electric circuit is not noticeable in the aircraft, but it is very important to ensure the aircraft to flight safety. Once the electrical circuit fails, the electrical energy or electrical control signals will not be transmitted effectively, which will affect the normal operation of airborne equipment, lead to the flight mission cannot be completed, and even endanger the flight safety. This paper analyzes the common fault forms and causes of aircraft electrical circuit, summarizes the common fault detection and analysis methods of aircraft electrical circuit, and provides some suggestions for how to effectively prevent the aircraft electrical circuit faults.
