基于容流匹配的空中交通流控指令发布时机研究

Research on Timing of Air Traffic Flow Control Instructions Based on Capacity Matching

现阶段管制运行过程中,流控指令作为空中交通流量管理的一种具体措施,在战术流量管理阶段其发布与实施的时机对空域运行效率和安全有很大影响.以容流匹配为基础,结合空中交通容量与流量预测、流控损失成本分析,建立空中交通流控指令发布时间决策模型与方法,最终判定拥挤空域内发布流控指令的最佳时机.以海南1和04扇区为实例,得出该空域由于天气原因导致空域容量减少时的流控指令最佳实施与发布时机.方法对减少航班延误传播,提高空域运行效率有一定参考价值.

At the current stage of the control operation,the flow control instruction is a specific measure of air traffic flow management.The timing of its release and implementation during the tactical flow management phase has a great impact on airspace operation efficiency and safety.Based on capacity matching,this paper combines air traffic capacity and flow forecasting,cost analysis of flow control costs,and establishes an air traffic flow control instruction issuing time decision model and method to determine the best time to issue flow control instructions in conges ted airspace.Taking sectors 01 and 04 in Hainan as an example,the optimal implementation and release timing of flow control instructions when the airspace capacity is reduced due to weather in this airspace is obtained.The method in this paper has certain reference value for reducing flight delay propagation and improving airspace operation efficiency.
