Abstract

In order to study failure cost of key waypoints and provide decision-making support for air traffic management departments and airlines, on account of China's air route network structure, a key waypoint identification algorithm based on diversion accessibility was proposed from perspective of transit time between airports. Then, the key waypoints identified were compared with those under other network indicators for invulnerability simulation. The results show that aircrafts have greater diversion accessibility when midwest connection nodes lose their traffic capacity, and their time cost of diversion is high. Waypoints on main routes such as A461, G212 and A593 have greater weighted diversion accessibility, and total time cost is high. Those identified key waypoints have larger degree and intermediate value. And continuous attacks based on degree value and weighted diversion accessibility cause bigger damages to air route network. © 2020 China Safety Science Journal. All rights reserved.
