面向飞行高度层优化的凝结尾和风因素综合指数法

Synthetic Index Method Based on Factors of the Contrail and Wind Facing Optimization for Flight Level

飞行高度层的选择是航空公司制定飞行计划的重要内容。为了节能减排、保护环境、提高航空公司利益,提出基于凝结尾和风因素的综合指数法来优化飞行高度层。将飞行高度层上的风和凝结尾因素归一化为风因数和凝结尾因数,确定最小综合指数对应的高度层为优化高度层。以四川航空公司成都双流至上海浦东的航段为例进行验证。实例表明,使用优化后的飞行高度层可以降低凝结尾的生成;并有效利用风向,达到节约成本,减少环境影响的目的。

The choice of the flight level is an important part of airlines flight plans.Focus on energy efficiency,environment protection and airline interest,a synthetic index method based on factors of the contrail and wind was proposed to optimize the flight level.The contrail and wind factors at the flight level are normalized to wind and contrail index,and the height corresponding to the minimum synthetic index is the optimum height.Finally,the case that the flight of Sichuan Airlines from Chengdu to Shanghai was studied.It is demonstrated that the use of the optimized flight height level helps to reduce the formation of contrails,save costs and decrease the impact of environment because of the effective use of wind direction.
