摘　　要：基于ADS⁃B IN的高度层变更程序(ITP),可以更加直观高效地实现高度层变更机动飞行。基于目标安全等级(TLS)获得侧向安全间隔,确保两架航空器不同时出现在冲突区域,建立了基于冲突区理论的ITP距离求解模型,分析了同向航迹夹角变化对ITP距离的影响。研究结果表明,ITP距离随着同向航迹夹角增大而增大,并随着ITP航空器爬升率的增大而减小。The In⁃Trail Procedure(ITP)based on ADS⁃B IN can realize the altitude level change maneuver flight more intui⁃tively and efficiently.The lateral safety interval is obtained based on the target level of safety(TLS)to ensure that two aircraft do not appear in the conflict area at the same time.The ITP distance solution model based on the conflict area theory is established and the effect of the change of the coincidental trajectory angle on the ITP distance is analyzed.The results show that the ITP distance increases with the increasing of similar track angle and decreases with the increasing of ITP aircraft climb rate.
