Based on the basic theory of wide-field electromagnetic method (WFEM) and combined with the current problems of resource exploration and the development status of aviation geophysical prospecting, the authors mainly deal with the aviation wide-area electromagnetic method in three main aspects as a preliminary exploration: basic theory, equipment research and application testing. It is held that the quality of aviation wide-area electromagnetic data collection is susceptible to aircraft flight attitude and aircraft body noise, and high frequency bands greater than 100 Hz have better data quality and practical engineering application feasibility.
