Prediction and compensation correction method and system for predicted arrival time of arrival flight

The invention discloses a prediction and compensation correction method and system for predicted arrival time of an inbound flight, and the method comprises the steps: monitoring flight data, obtaining a flight plan change condition based on a basic information library according to the flight data, and updating flight simulation information; performing flight simulation deduction on a target flight according to the flight simulation information, and predicting initial predicted arrival time of the target flight; the actual landing time of the target flight and the initial predicted arrival time predicted 30 minutes before landing are obtained, error results are calculated, the error results are classified and summarized based on an approach program, and an error sequence is formed; and carrying out compensation correction on the error sequence to obtain a prediction error, and obtaining the final prediction landing time of the subsequent arrival flight according to the prediction error.
