Abstract
As one of the cores of the new-generation civil aviation transportation system, China’s new-generation air traffic management system (CNGATM) includes various contents, such as track-based operation (TBO), which has attracted more and more scholars’ attention. Traffic management for all these periods is based on the aircraft’s four-dimensional (4D) trajectory. Based on the BADA database, this paper establishes a track simulation model, obtains the flight track through simulation experiments, and analyzes the characteristics of the track. Combined with the flight dynamics model, through the study of the four-dimensional (4D) trajectory of the aircraft, the uncertainty of the aircraft path is significantly reduced, and the utilization and safety of airspace and airport resources are improved.
