    Abstract: 大氣層中的天氣系統發生於對流層內,而長程飛機為了避免天氣的影響,往往會爬升至10公里以上的高度,但是幾次嚴重的空難事故,如2009年的法航447班機空難和2014年的亞航8501空難,都是發生在飛機巡航階段,由10公里以上的高空失速墜毀,根據事後的事故調查,駕駛在面對發展至上對流層的天氣系統時錯誤的拉拔機鼻,進行爬升是造成失速的主要原因,當時飛機在一分鐘內爬升1.5km,飛行攻角過大而無法從環境取得足夠的升力,造成失速。
    ;To prevent the influence of weather system in troposphere, commercial airplane always fly above 10 kilometers. But some air crash occurred when airplane flight above 10 kilometers, for example Air France Flight 447, which crashed on 1 June 2009 or AirAsia Flight QZ8501 which crashed on 28 December 2014.
    The result for AF447 air crash in Final report, the pilot made an abrupt nose-up input on the side-stick, an action that was unnecessary and excessive under the circumstances. The aircraft′s angle of attack increased, and the aircraft started to climb , it was climbing at nearly 7,000 ft/min. The aircraft′s angle of attack is so large that aircraft fell off.
    In-service Aircraft for a Global Observing System is a plan that use in-service aircraft to observe ozone, water vapor, carbon monoxide. When I analysis the data from IAGOS, almost of all flight fly at stable flight level, but some flights changes the height, the variation of height is about 1 to 2 kilometer. This phenomenon is interesting for me. In this study, I want to understand the cause of this phenomenon by using HYSPLIT model to calculate the vertical movement of the environment, and discussing the interaction between environment and aircraft.
    HYSPLIT model is run using GDAS half-degree archive. Except calculating the real location of aircraft by HYSPLIT model, also calculating the location near 2.5 degree longitude and near 1 and 2 kilometer of height. The result show that the relationship between vertical movement of the environment and the change of aircraft is high variable.
