Electromagnetic Compatibility Evaluation in Test Flight of Avionics Communication Systems

Electromagnetic compatibility(EMC) is the main performance of avionic electronic products and an important guarantee for the realization of system functions.Flight test is to verify some expected idea by providing data acquired from real flight conditions,and the test performance is analyzed and evaluated by the results of flight test data.Therefore,EMC prediction is one of the main contents in test flight of avionic communication systems.The EMC evaluation method based on electromagnetic topology(EMT) is discussed in this paper.The proposed method has been used in avionics communication system flight test.
