4D Trajectory and Controller Command Generation Based on Schedule Time of Arrival

In order to support the construction of ATC automation system, a four-Dimensional Trajectory (4DT) and controller command generation method based on Schedule Time of Arrival (STA) is proposed. Firstly, four main models of trajectory generation are given: point-mass model, performance model, weather environment and intention model, and the process of trajectory generation is described. Secondly, two methods of generating 4DT according to STA are studied, which are adjusting speed parameters and adjusting command timing. Finally, Guangzhou Baiyun airport is simulated as an example. The result indicates that both optimization methods can meet the requirement of STA, but the command-based method is more consistent with the current control mode, which has a broad application prospect.
