摘要:: 基于航迹运行是新一代空管运行的发展趋势，因此，为准确和高效地描述民航飞行航迹，提出了基于航线对象方法的7种航迹段模型。按照飞行计划、管制指令和导航设备的地理分布，搭建了水平航迹，对垂直剖面建模所需的重要参数（爬升率、下降率、推力、巡航马赫数等）进行了简单的推算和优化，可以生成完整的4D航迹。最后通过离场队列飞机的仿真算例与实际飞行数据进行比较，结果表明该建模方法可准确描述航空器各点的空间位置和时间，能较好地描述终端区的动态航迹，对交通流调控的实用化有积极的作用

Abstract:: Trajectory based operation was the development trend of new generation air traffic control operation. In order to describe the trajectory of civil aircrafts precisely and efficiently, the seven new trajectory model based on path object was proposed. Horizontal trajectories were built depending on the flight plan, control instruction and geographical distributing of navaid, the requisite main parameter, in- cluding ascension rate, descent rate, thrusting and cruise Mach, for vertical profiles modeling were simplied reckoned and optimized, a whole 4D trajectory was obtained. Finally, a comparison between a departure simulation data with the actual flight data shows that the 4D trajectory model based on path object can describe the spacial position of the aircrafts accurately, and resolves the trajectory prediction problems that exist in terminal area describe dynamic trajectory of the terminal area better. It has positive effect on the practical traffic flow adjusting and controling
