Electromagnetic compatibility test for aircraft system

The electromagnetic compatibility (EMC) test for an aircraft system has no available and official standards or regulations in China. In connection with EMC test for a certain aircraft and its electric subsystems, we put forward a test program for aircraft AC/DC power supply system characteristics, electromagnetic emission, electromagnetic susceptibility, and electromagnetic environment and antenna coupling. We not only determine the EMC safety margin of the aircraft system from a system viewpoint, but also evaluate the EMC performance of some key airborne equipment from an equipment viewpoint.
