摘　　要：为快速准确地预测民航飞行航迹,提出了基本飞行模型的概念.按飞行阶段特点用基本飞行模型构建水平航迹、高度剖面和速度剖面,根据航迹特征点的飞行状态信息(位置、高度、速度和航向)拟合生成完整的4D航迹.离场程序仿真算例与实际飞行数据比较表明,基本飞行模型航迹预测方法可以快速得出航迹特征点和到达航迹特征点的时间.To predict the trajectory of civil aircrafts efficiently and precisely, a new concept, basic flight models, was proposed. Horizontal trajectories, altitude profiles and speed profiles were built using the models depending on the flight phases. A whole 4D trajectory was obtained by combining the flight states of characteristic points of trajectory, including position, altitude, speed and heading. A comparison between a departure simulation data with the actual flight data shows that the prediction method based on basic flight models can obtain the characteristic points of flight trajectory rapidly and predict the time an aircraft arrives at the points with a reasonable accuracy.
