Abstract: One valid way to solve the flight delay problem is improving the efficiency of air traffic control (ATC). With the aspect of control sectors, the basic units of ATC system, using the method of complex networks, an ATC sectors network is established, which considers the sectors within a certain range of airspace as nodes and the relationships between each other of flight as edges. Furthermore, the Area Control Center of North China is given as an example to verify the property of small average path length and small clustering coefficient. The distribution of degree is pretty homogeneous, which is different from strength and betweenness whose distribution conform to some functions. Invulnerability of sectors network is studied, indicating the significant metric, which determines the critical sectors and the potential critical sectors.

Key words: complex network, control sectors, betweenness, network efficiency, invulnerability
