Study on 4D Track Prediction and Optimization of Aircraft Climbing Phase

摘要

To meet the ever-increasing air traffic flow demand for flight track prediction accuracy in Air Traffic Control, according to the standard flight profile and the real flight plan, the Total-Energy Model and related performance parameters in the BADA database were used to perform numerical simulations on the takeoff phase of the aircraft. We compared the predicted altitude, speed, and voyage results with the actual radar track data simultaneously acquired by regional Air Traffic Control systems in Shenyang, etc., and analyzed the sources of errors. And this would further dig the aircraft intention information and extract the empirical parameters to optimize the aircraft climb profile. The optimized model was used to simulate and predict real flights of different aircraft and different landing airports. The results show that the climbing profile optimization strategy is feasible and effective, and the optimized track prediction accuracy is obviously improved.
