摘　　要：通过对比气压高度和无线电高度的特点,分析了气压高度误差对RNP进近的影响。提出了5种RNP进近航径交叉检查方法。通过实地试飞QAR数据分析,发现了一次不成功进近的主要原因。分析结果表明,气压误差将导致RNP五边进近偏离标称航径。The effect of baro-ahitude error on RNP approach was analyzed by means of comparing the characteristics of baro-ahitude and radio altitude. Five methods were proposed which can be used for cross-checking RNP approach final path. The main reason for one unsuccessful RNP approach was found through the analysis of flight test QAR data. The results show that the barometric error will cause actual RNP final path to deviate from the desired path.
