摘要
在现有航空运输系统的能力已经不能满足空中交通流量需求的前提下,基于精确的4D轨迹运行是未来空中交通管理(ATM)系统的基础,以实现飞行轨迹的优化。文章研究基于航空器性能及运行程序的数据模型系统的建立方法,可应用于4D轨迹预测,可大大降低或避免空中发生飞行冲突的可能性,提升空中交通安全,提高空中交通流量。
Due to the difficulty of capacity of transportation system to satisfy with the growing air traffic flow,air traffic management system based on precise 4 Dtrajectory is expected in the future to forecast flight trajectory.This essay proposes an improved 4 Dmodeling method on the basis of performance and operation data originated from various kinds of aircrafts.To put the method into practice,the possibility of flight conflict can be reduced or avoided,the safety of air traffic is ensured,thus the volume of air traffic is increased.
