The invention provides a flight plan track prediction method based on an informer + arima model. The method comprises the following steps: S1, preprocessing historical track data; s2, taking the preprocessed historical track data as a training sample, carrying out informer model training, and repeatedly and continuously adjusting parameters to form an optimal informer model; s3, taking the preprocessed historical track data as a training sample, carrying out arima model training, and repeatedly and continuously adjusting parameters to form an optimal arima model; and S4, finally predicted four-dimensional track data is obtained by using the optimal informer model and the optimal arima model. According to the method, on the basis of a fusion model of two networks of informer and arima, prediction of linear relation data and nonlinear relation data is supported, a weight empowerment strategy is added, and four-dimensional track data of a flight plan can be predicted more accurately.
