A Quasi-Statistical Approach to Aircraft Induced Effects Characterisation

In order to demonstrate comprehensively for every cable to every flight safety critical equipment on an aircraft, that the qualification test levels were greater by a margin than the levels of induced threat on the aircraft, it is necessary to measure the current or voltage on all of those cables during whole aircraft tests. In this paper an approach is described which relies on a statistical distribution of induced threat amplitudes in the cables within an airframe to reduce the number of cable measurements needed, and fill in for cables that cannot be measured. The method also offers, for the first time, a viable approach to the substantiation of a similarity argument.
