摘要:

准确的五边垂直航迹计算是飞行安全评估的基础。结合实地飞行运行的QAR数据,通过Matlab对RNP APCH 飞行运行的五边垂直航迹进行拟合分析,对验证RNP APCH程序QAR数据的精度和完好性提供了一种参考性的方法。同时还原导航数据库中定义的标称航径,辅助QAR 数据分析气压高度误差对RNP APCH进近的影响。结论较好地满足了RNP APCH运行飞行技术安全评估对高精度五边垂直航迹的需要。

Abstract:

Accurate final vertical trajectory calculation is the basis of aircraft flight safety assessment. By using QAR data of flight operation to analyse vertical track of RNP APCH through Matlab,an method for the verification of accuracy and integrity of RNP APCH QAR data is proposed. Furthermore,the final nominal flight path of Navigation DataBase is reverted and the effect of pressure altitude error in RNP APCH operation is evaluated and analyzed. The conclusion meets the high-precision vertical track requirements of RNP APCH operation flight safety assessment.

Key words: PBN, Matlab, RNP APCH, vertical trajectory fitting, navigation DataBase, pressure altitude
