Abstract: In order to ensure the safety of aircraft operations in the sector,improve the resilience of the sector network under external disturbance, and thereby effectively reduce flight delays and airspace congestion,by using complex network theory, an airspace sector network model of China is established based on airspace sector division rules. Then, the structural characteristics of airspace sector network are analyzed by defining basic network parameters. In addition, the concept of sector network resilience is defined and a quantitative evaluation method is used to measure it. Finally, resilience indicators under different recovery strategies are comparatively analyzed, so as to develop the optimal recovery strategy of the sector network under external disturbance and improve the network resilience. The results show that the airspace sector network of China has a lengthy average shortest path and a small clustering coefficient. The degree distribution follows a double power-law distribution and the cumulative distributions of betweenness follow an exponential distribution. Among them, betweenness has the greatest impact on the resilience of airspacesector network. Adopting the betweenness recovery strategy can significantly improve the airspacesector network resilience under external disturbance.
