This paper deals with the direct effects of lightning strike on aircraft structures. In a first part, the phenomenology of lightning arc attachment on aircraft is introduced. Some specific features of lightning arcs observed in flight or created in the laboratory are presented. Some recent developments and results from numerical simulations are shown. The shapes, the behaviors and other specific points are compared with experiments, in order to bring to light some explanations on the...
