Abstract: The lightning is a threat to the safety of flying aircraft.In order to further determine the characteristics of lightning stroke to aircraft,according to SAE-ARP5416 "Aircraft Lightning Test Methods" and relevant standards of our country, simulation methods based on finite element are used to simulate lightning attachment points and lightning zoning on the Airbus A320.A new simulation method of aircraft zoning is proposed.Relevant content about simulation model is discussed. The division of 1A zone of the lightning zoning is present and the numerical results are compared with SAE-ARP5414 Astandard.The presented method and numerical results are of great value to lightning protection of aircraft and related studies.
