摘要
在地面管制单位服务能力完全丧失的紧急情况下,应急航路是保证一定数量航空器能够在失能空域中继续运行的重要手段之一。通过分析繁忙航路点的交通流时间序列特性,以相似交通流模式为依据,研究应急航路的划设方法。以此为基础,根据北京区域管制中心的实际航班运行数据,在简化的航路网中,基于欧氏距离的相似性度量,对不同航路点的时间序列进行层次聚类,通过设定距离阈值,并结合航路连接方式、冲突点等综合因素,划设北京某管制空域的应急航路,以保证少量航班在空域失能状态下继续安全运行,减小地面空管单位的管制压力。
Contingency route is an important means of ensuring a certain amount of aircraft keep flying in the airspace of air traffic control zeros where the ground control units totally lose their service competence. A programming method of contingency route was developed in this paper on the basis of similar traffic flow pattern by analyzing the characteristic of traffic flow time series in busy waypoints. Furthermore, a hierar- chical clustering method based on similarity measurement of Euclidean distance was used to analyze time series of different points in generalized airway networks according to the actual flight operating data in Beijing Area Control Center. Contingency routes were programmed for a certain controlled airspace in Beijing by selecting different distance threshold values combined with some composite factors such as route connection type and conflict points. With this method, a minority of aircraft can keep flying safety in the airspace of air traffic control zeros, and the working pressure of the ground control units can be reduced.
