Abstract

Evaluation of controlled airspace capacity based on the controllers’ workload is the most wildly used theoretical evaluation method of controlled airspace capacity currently in China. This method uses the aircraft sorties to be the only metric. It identifies some quantitative relationship between the metric of aircraft sorties and controllers’ workload. The method then figures out the controllers’ workload and evaluates the capacity value limited by the controllers’ workload ability in the controlled airspace according to the DORATASK method. But in actual operation, aircraft sorties is not the only Influencing factor of controllers’ workload. Therefore, a new evaluation method of controllers’ workload based on the metric of traffic complexity is proposed. This new method uses a group of multidimensional metric of air traffic complexity to research and solve the problem of evaluating the controllers’ workload, Instead of using a traditional single traffic measurement- aircraft sorties. The method is applied in the capacity evaluation project of control sector 02 in Shanghai. The evaluation results are recognized by the front-line ATC experts. Meanwhile they also verify the feasibility and correctness of the method applying to the airspace capacity evaluation.
