Abstract
An aircraft four-dimensional(4-D) trajectory prediction method is proposed for the pre-tactical stage. The method is based on point mass model and total energy model to establish aircraft dynamic model and wind correction model, and use the wind forecast data to correct the trajectory, and gradually deduce the 4-D trajectory by computer recursive method. Based on the flight plan and the aircraft performance data in BADA3.11, the 4-D trajectory of the flight can be predicted. Finally, the accuracy of the prediction method was verified for flight KLM888 on the VHHH-EHAM international long route, where the difference between the predicted trajectory flight time and the planned flight time was only 0.73%.
