This paper proposes a comprehensive method for evaluating the vulnerability of integrated airspace networks, considering both structural and functional vulnerabilities. First, a weighted network of air segments is constructed, where weights are assigned based on segment capacity, traffic flow, distance, or average transit time under varying ratios of manned to unmanned aircraft. A weighted network efficiency index is defined. Next, critical waypoints are identified by analyzing changes in the weighted network efficiency index under network disruptions and the operating cost index under flight scheduling adjustments. Finally, the network's vulnerability is assessed using the total delay cost as an indicator, based on deliberate attack scenarios. Using the integrated airspace flow network in East China as a case study, the analysis demonstrates that the weighted efficiency index effectively identifies functionally vulnerable nodes and can be used for efficient assessment of the network vulnerabilities.
