EMC′s definition,purpose,design process,experimental content and demand are introduced in this paper. Four aspects (cable design, mechanical design, power filter design, and computer power ground and signal ground design) to achieve airborne computer EMC are proposed according to the characteristics and engineering practice of airborne computer EMC. By summarizing the issues appearing in airborne computer design and testing,the mechanism that the problems occured was analysed in theory. The practical engineering solutions are put forward. The solution must pass EMC test verification because the EMC technology is experimental science,the author stressed emphatically.
