中文摘要：

由于飞机在着陆阶段的飞行环境复杂且飞行员操纵参数众多,对飞机的飞行安全提出了严峻考验。因此,以飞机着陆阶段的油耗模型为例,提出了参数优化分析方法,优化影响油耗的参数,从而简化飞行操作。结果表明,优化后,影响飞机着陆阶段燃油消耗的因素由十个减少为四个,并且油耗预测模型的预测精度基本不变,模型结构简洁,从而更好地保证了飞机飞行安全。

英文摘要：

There are severe knots to the flight safety of aircraft in terminal descent of the aircraft because of complex flight environment and many manipulate parameters.Method of analyzing fuel consumption NN model is put forward to optimize the parameters affecting fuel consumption in order to simplify flight operations.Results show that the number of factors affecting fuel consumption is reduced from ten to four as a precondition to basically unchanging fuel consumption prediction precision,which ensures flight safety better.
