飞机航路客舱释压应急程序研究

Study on Airplan Enroute Cabin Depressurization Emergency Procedure

本文引述了中国民航规章关于客舱释压后为机组成员及旅客供氧的要求,以空客A320-214机型执飞丽江-昆明航段为例,采用飞机性能软件,计算飞机航路客舱释压后紧急下降性能;使用有效地形数据源,获得航路最低安全高度。通过超障分析,方案论证,最终选择设置决断点及偏置航路飞行的方法,设计航路客舱释压应急逃离程序,以满足航路客舱释压后飞机安全飞行的目的。

This article presented the cabin crew and passenger oxygen requirements after cabin depressurization according to CCAR regulations. Taking a flight from ZPLJ to ZPPP with A320-214 fleet as an example, it calculated the airplane emergency descent performance by using airplane performance software; Obtained enroute minimun altitude by using effective relief data. After obstacling clearance analysis and methods demonstration, an enroute cabin depressurization emergency procedure by setting a decision point and deviating flight from original route was designed, which can ensure a safe flight after cabin depressirazation.
