基于模糊正态分布的进近段风险评价

Assessment of Ground Proximity Risk on Final Approach Based on Fuzzy Normal Distribution

将模糊性中间型正态分布隶属函数应用于飞机进近段近地碰撞风险模糊综合评判中,不仅考虑到气象及人为因素,而且可以将评价结果用定量的信息进行描述。通过实例分析,模糊正态分布隶属函数可以将飞机近地运行状态和飞机及环境因素有效地关联,恰当地反映当前飞行状态。

The fuzzy intermediate normal distribution membership function is employed in the comprehensive assessment of ground proximity risk on final approach, with meteorological and human factors taken into account, and the result of assessment can be described in a quantitative manner. Through real case analysis, the aircraft ground proximity status can be effectively correlated with factors of airplane itself and the surrounding environment by applying fuzzy normal distribution membership function and a thorough picture of current flying status can be given.
