民用飞机运行环境适应性影响因素研究

Research on Influencing Factors of Operation Environmental Adaptability for Civil Aircraft

民用飞机运行环境是指民机运行所处的外部条件。不同机型的运行环境适应能力有所差别。本文根据飞行的不同阶段将民机运行环境划分为起降运行环境(或机场运行环境)和航线运行环境。通过对飞机起降运行环境和航线运行环境的分析,分别研究了能见度、云高、风、跑道长度、温度、机场标高、航程、飘降限制、供氧限制、燃油经济性限制等因素对飞机放行和最大起飞重量造成的影响,并结合飞机的飞行手册等数据,分析比较了波音737-800、767-200、787-8的运行环境适应性。

The operation environment means external conditions where civil aircraft work. There are differences about the operation environmental adaptability between each individual type of aircraft. This paper divides the aircraft operation environment into the environment of take-off and landing and the environment of line operation, based on the different stages of flight. Through analysis of the environment of take-off and landing and the environment of line operation, we＇ve studied such factors as visibility, cloud height, wind, runway length, temperature, airport elevation, range, restriction of drift down, restriction of oxygen providing and fuel consumption, which influence dispatching decision and maximum take-off weight of aircraft. And then the operation environmental adaptability of 737- 800,767-200 and 787-8 are compared with each other by using the data in these aircraft＇ flight manual.
