Problems solved by technology

[0005] In many cases, multiple airborne equipment on the aircraft have electromagnetic compatibility conduction interference failures at the same time, which cannot meet the requirements of GJB151A-1997 on conducted emission and conducted sensitivity tests

However, there is currently no reasonable and feasible repair method for EMC conducted interference faults, and it is impossible to determine the priority relationship of the rectification sequence of airborne equipment with EMC conducted interference, which often makes EMC rectification work time-consuming, repetitive and costly, and even leads to aircraft failure.
