The use of electrical energy is constantly increasing in airplanes. This concerns needs in motor, actuators or those related to services for example. Naturally the electric energy-related risks increase. Arc discharges can appear with consequences that can be dramatic. The electrical constraints to which a plane is subject are not only internal. The aircraft are also regularly struck by lightning in-flight. Composite materials, increasingly used, make more difficult the management of these risks of lightning strikes. So the arc discharge is a concern in the aeronautical domain. This specific area imposes special conditions that do not exist in other areas where the arcs are present. Our intervention is intended to present these studies, with in the rest of this paper, references to two specific topics, the arc fault in the electric core of aircraft and damage to the composite by structure being struck by lightning.
