Lightning strike to aircraft is a threat to flight safety. During the strike, the lightning channel sweeps along the body of the aircraft. The voltage gradient of the lightning channel is one important property that determines where on the aircraft it may sweep is its voltage gradient. This report presents an analysis of this voltage gradient for the purpose of numerical lightning swept stroke simulations.
