摘　　要：介绍一个利用下降轨迹的优化来减少燃料消耗和污染物排放的案例研究。抵达航班通过一系列基线下降轨迹的转换,观察到的雷达跟踪数据的采集和怠速油门的下降轨迹来沿垂直面下降。对基线的轨迹和抵达航班,以及它们的连接进行了深入的描述。对两种白天运营的优化下降程序的实施方案(无约束和约束)进行了分析。对在无约束优化下降和约束优化下降的情况下双方的潜在利益和冲突造成的这种运营情形进行量化。优化下降到场程序的操作过程是可以实现的,燃油和排放节省了效益,同时避免与其他交通的冲突。A case of optimizing descent trajectory to save fuel and reduce pollutant emission is introduced in this paper. Ar-rival flights descend along optimized vertical profiles by transforming the descent trajectories of a set of baseline,acquisition of observed radar tracking data and descent trajectory of idle speed throttle. Baseline trajectory,arrival flights and their connection are described in detail. Two implementation plans（unconstrained and constrained）of optimized descent procedures during day-time operations are analyzed. In the case of unconstrained and constrained optimized descent,the operations caused by both the potential benefit and conflict are quantified. Procedures for optimized descent arrival operations can be implemented with fuel saving and emissions reduction. It mat avoid conflicts with other traffic.
