Aiming at meeting novel customers\' requirements many companies worldwide design and produce new aircrafts for public, cargo and other special transportations. In order to be legally exploited, a flying machine has to fulfill a number of different, foremost safety, requirements.
One of such demands is EMC of the on-board electrical and electronic systems, namely the stability of the equipment against external electromagnetic influences: powerful impulse electromagnetic fields, caused by lightning, and high-intensive radiated fields, created by powerful ground transmitters. The countermeasures are the equipment covers and the aircraft shell which act as thin-walled screens with structural inhomogeneities. Their protective features, however, are the subject of degradation and therefore should be recurrently certified. The novel automated method is being developed.
