摘　　要：垂直航径角是RNP AR最后进近程序设计中的重要参数。Doc 9905号文件第三版更新了实效垂直航径角的计算方法。本文通过比较第二版与第三版实效垂直航径角计算方法的不同,分析了环境条件对垂直航径角影响的变化规律,分析了温度对实效垂直航径角的影响。运用实际机场的RNP AR程序进行了验证分析,为检验RNP AR飞行程序的适用性提供了理论参考。Vertical path angle is an important parameter of RNP AR final approach procedure design. The algorithm of effective vertical path angle is updated in ICAO document 9905 third edition. Variation rule of the influence of environmental conditions on vertical path angle is analyzed by comparing the differences between the effective vertical path angle algorithms of second edition and third edition. The influence of temperature on effective vertical path angle is analyzed. The RNP AR flight procedures of actual airports are used to verify and analyze the algorithm, providing theoretical reference for checking suitability of RNP AR flight procedures.
