Abstract
It is a view held by many, but not all, that whole aircraft testing for measuring levels and waveforms of induced cable currents and voltages should be carried out at moderately high levels of imposed external threat. The reason for this proposal is that the are a number of effects occurring during the passage of a lightning strike that will result in different cable transient amplitudes and wave-shapes, depending upon whether certain current or voltage thresholds are exceeded. These are the so-called non-linear effects. In this paper we argue that it is neither practicable nor technically correct to attempt to emulate these effects and test at very low injected current levels.
