With the fast development of information technology and the increase of spectrum user,spectrum has become a very rare resource. Due to large amount,multiple functions,wide operation band and complex electro-magnetic environment of avionics equipment,co-site interference is inevitable. It is a key point for a good plan of frequency in the flight-test. Based on the analysis of the avionic communication system,a frequency manage-ment method is introduced which uses the spectrum sensing technology. This method can improve the spectrum usage and support the analysis and rebuilding of the flight-test data,and improve the evaluation veracity of the avionic communication system′s flight-test.
