高原航线飘降释压应急程序设计研究:以A319-115“西宁/曹家堡-玉树/巴塘”航线为例

Study on emergency procedure design of drift and pressure relief of A319-115 on plateau route

为确保高原航线运行安全,保证机组在非正常情况下单发飘降应急程序和客舱释压紧急下降应急程序可用,以空客A319-115飞机执行“西宁/曹家堡-玉树/巴塘”高原航线为研究样本,依照2021年8月12日零时开始实施的202108期《中国民航国内航空资料汇编》显示的航线信息,通过梳理航线的基础数据,在满足相关规章要求的条件下,统筹兼顾航空公司安全、效益、服务的需求,完成单发飘降应急程序和客舱释压紧急下降应急程序设计与研究,以便于机组操作为原则,课题组优化相关应急程序的决断点,最后定义出机组操作程序,研究表明:通过对应急程序关键点的确定,定义出飘降释压后的机组操作程序,完成剖面示意图的绘制,能达到紧急情况下安全飞行的目的,该研究成果在同类高原航线具有推广意义。

In order to ensure the safety of the plateau flight route and the availability of the emergency procedures for single floating landing and cabin pressure relief descent under abnormal conditions, the “Xining/Caojiapu-Yushu/Batang” plateau flight of Airbus A319-115 was taken as the study sample.In accordance with the route information displayed in the 202108 Issue of the Civil Aviation Industry of China(CAAC) Domestic Aviation Data Compilation, which was implemented at 00:00 on August 12, 2021, and by sorting out the basic data of airlines and meeting the requirements of relevant regulations, overall consideration was given to the safety, efficiency and service needs of airlines. To complete the design and research of emergency procedures for single-engine floating descent and cabin pressure relief emergency descent, the research group optimized the decision points of relevant emergency procedures and finally defined the operation procedures of the unit. The research shows that by determining the key points of emergency procedures, defining the crew operation procedures of the unit after flapping and pressure relief, and completing the drawing of the profile diagram, the purpose of safe flight in emergency situations can be achieved. This research achievement has popularization significance in similar plateau airlines.
