Abstract

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
