摘要
随着高原航线的不断开航,如何确保飞机航路巡航过程发生发动机失效后的飞行安全是各航空公司面临的新问题。以空中客车A319-115执行“日喀则/和平—北京/首都”航线为样本,使用飘降净升限检查航路最低安全高度判断安全超障的方法,完成巡航中出现一台发动机失效后飘降程序的设计,并定义机组操作步骤。结果表明:高原航线对飞机性能要求很高;设计有效、易操作的发动机失效应急飘降程序和机组操作步骤对高原飞行安全有积极的作用;应急飘降程序必须满足飞机越障的要求;对于航程较长的高原航线可以采用分航段的形式完成应急飘降程序的研究。研究成果对类似高原航线的安全飞行具有参考价值。
With the continuous opening of plateau routes,how to ensure the flight safety after the engine failure occurs during the cruising process of the aircraft is a new problem faced by various airlines.Taking the air passenger car A319-115 which flies the"Shigatse/Peace-Beijing/Capital"route as a sample,the method of using the drifting net ceiling to check the minimum safe altitude of the route to judge the safety of overcoming obstacles was applied to design the drifting down procedure after an engine fails during cruise,and define the operating steps of the crew.The results show that:plateau routes have high requirements on aircraft performance;design effective and easy-to-operate emergency descent procedures for engine failure and crew operation steps have a positive effect on plateau flight safety;emergency descent procedures must meet the requirements of aircraft over obstacles;for plateau routes with longer voyages,the study of emergency drifting procedures can be completed in the form of sub-segments.The research results have reference significance in the safe flight of similar plateau routes.
