Some problems are solved by the safety design of airborne electronic equipments in complex electro.magnetic environments. Firstly, the safety problems caused by the work disorder of airborne electronic equipmentswhich are caused by electromagnetic induction and coupling. Secondly, the safety problems are caused by mal func.tion when induced voltage or current produced by electromagnetic induction and electromagnetic coupling reachesor exceeds the relevant performance characteristics with the airborne electronic equipments working properly. Final.ly, the importance and necessity of the electromagnetic environment safety design of the airborne electronic equip.ments are showed through introducing a situation of the electromagnetic safety design for a typical airborne electron.ic equipment in a complex electromagnetic environment.
