All aircraft systems must be designed to ensure electromagnetic compatibility with the electromagnetic environment (EME) in which they are intended to operate. Both lightning and high‐intensity radiated fields (HIRF) are external EME elements, thus posing threats to the complete aircraft at the same time. A situation, where a wire bundle is located near a hole in conducting aircraft skin, can be represented as an aperture‐wire configuration. The HIRF environments are a composite of transmitters that are airborne, land based, off‐shore platforms, and ship‐borne. Typical high‐frequency communication systems are using of modulation techniques such as Amplitude modulation, frequency modulation, pulse modulation, or continuous wave. The high‐level direct drive test is normally used at frequencies below the first aircraft resonance. The idealized standard external voltage waveforms represent the portion of the electric field important for assessment of different discharge processes associated with a lightning strike to aircraft.
