Summary:The invention provides a novel method for dividing a lightning partition into a first area (including a 1A area and a 1B area), which comprises the following steps of: constructing an airplane and a discharge cloud layer model, and taking a pitch angle, a yaw angle and a roll angle which are zero degree as a reference simulation model, whrein in combination with an SAE-ARP-5414A standard partitioning theory, repeated simulation analysis shows that the area 1 based on charge distribution is partitioned by taking about 35% of the maximum charge density induced on the surface of an airplane as athreshold value, and the area exceeding the threshold value is determined as the area 1 of a lightning partition; under different pitch angles, yaw angles and roll angles, acquiring aircraft surface charge distribution conditions under different angles; and according to the aircraft surface charge distribution conditions at different angles, performing statistics to obtain lightning division conditions of the first area o
