起飞推力限制参数验证试飞（lapse-rate take off，简称LRTO）是飞机高高原动力试飞的核心科目之一。该科目在高高原试飞时，需要在高高原机场的最低安全高度（minimum safety altitude，简称MSA）以下飞行。针对高高原起飞推力限制参数验证试飞的飞行航迹设计进行了研究。介绍了扇区最低安全高度的定义和CCAR91部对低高度飞行的适用条款。阐述了航迹设计的基本要求，包括保护区的定义和要求、航迹精度的构成。详细描述了低于扇区最低安全高度飞行航迹的设计方法，包括试飞区域地形数据的获取、航迹绘制的经验总结、航迹的性能校核、模拟机校核和真机飞行时的逐步逼近。以稻城亚丁机场为例介绍了设计完成的飞行航迹在稻城机场应用的情况，包括航迹在实际应用中的超障余度和应用时的气象要求。
LRTO(lapse-rate take off) is one of the most important subjects of engine flight test on high elevation airport. It requires applicant to fly below MSA(minimum safety altitude) when conduct LRTO flight test on high elevation airport. This paper mainly focuses on the flight track design of LRTO on high elevation airport. The first part introduced the definition of MSA and the applicable provision of part CCAR91. The second part described the basic requirements of the track design, including the definition of protection zone and accuracy of flight track. The third part focused on all details of track design and check methods, including the acquisition of terrain data in flight test area, the experience summary of track drawing, the performance verification of flight track, the verification of simulator and the gradual approach of real aircraft in flight test. At last, taking Daocheng Yading airport as an example,the application of the flight track of LRTO at DCY airport was introduced, including obstacle clearance and meteorological requirements.
