Abstract: Area capacity evaluation is an essential and a key point to the effective implementation of air traffic flow management. It plays an important role in reducing flight delays and ensuring flying safety. With the increase of air traffic flow, the controller’s workload is rising and it has become one of the most important factors of the sector capacity. This paper deeply analyzed the controller’s workload model and the capacity evaluation from the aspects of both theory and practice. The definition of the controller’s workload was firstly introduced and the workload classification was put forward. Then the theory of evaluation model, which is based on the statistic of route flow, was established. After that, a specific method to evaluate the controller’s workload was discussed. Finally, based on the real data of Lanzhou airspace, the new controller’s and qualified controller’s workload evaluation for one sector was conducted with the presented model by regression analysis. The result accorded with the practice and validated the validity of the proposed model and method.
