This article discusses issues related to indirect lightning on aircraft/rotorcraft. The
standard waveforms used for qualifying the vulnerability of a system are introduced,
with their frequency spectrum. The identification of the elementary EM coupling phenomenon
allows the understanding of the key drivers of the current distribution and field
scattering on a complex structure. The system level EM coupling analysis starts with
examples of cable-measurements on real aircraft/rotorcraft, from which simple models
are derived in order to understand the origin of the resulting waveforms. Various ways
of protection are then proposed, ranging from passive to active solutions. Finally, despite
limitations, 3D EM modeling is presented as an efficient complement to scale-one
tests. The article concludes on the validity of current knowledge on indirect lightning for
future aircraft designs.
