The invention discloses a method for determining the aircraft scale proportion of an aircraft lightning partition test, which comprises the following steps of: processing simplified aircraft scale models with different proportions by simplifying an aircraft model, and carrying out a simplified lightning attachment test on the simplified aircraft scale models to determine the aircraft scale proportion of the aircraft lightning partition test. Calculating the attachment probability from the lightning attachment point to the vertical fin and the aircraft back of the simplified aircraft scaling model in the horizontal flight attitude positive polarity discharge state, and judging the conformity between the lightning partition test result obtained in the specific scaling test and the result of the real aircraft lightning initial attachment point; therefore, the optimal scaling ratio of the scaling model used in the thunder and lightning partition test is determined. According to the method, the appropriate scaling ratio can be accurately determined, and favorable support is provided for rapidly judging the conformity of a lightning partition test result obtained in a specific scaling test and a result of a real aircraft lightning initial attachment point.
