PBN(performance based navigation)飞行程序在国内运输机场应用广泛,PBN飞行程序设计的工作难点是最后进近航段障碍物评估,为了提PBN飞行程序设计的工作效率、降低出错率,本文将基于目前飞行程序设计常用的工作平台auto CAD,建立障碍物评估模型并研究开发能自动生成最后进近航段保护区、能自动进行障碍物评估的辅助软件,使用某机场数据进行测试,经过测试验证,此辅助软件的计算过程正确、计算结果的精度符合要求。
PBN (performance based navigation) flight program is widely used in domestic transport airport. The difficulty of designing PBN flight program is the assessment of obstacle in the final approach segment. In order to improve the efficiency of PBN flight program design and reduce the error rate, Flight program design commonly used working platform auto CAD, the establishment of obstacle assessment model and research and development can automatically generate the final approach section protection zone, can automatically assess the obstacles of the auxiliary software, the use of an airport data for testing, tested and verified, The calculation process of the auxiliary software is correct, and the accuracy of the calculation result meets the requirements.
