Abstract:

It has been regarded as a remarkable front-line safety management measure，dual position system implemented in China requires a balance between the executive controller and the co-ordination controller on the basis of air traffic controller's workload. An assessment model of controller workload has been established by using timeline analysis and the DORATASK method. The whole workload of the sector is divided into controlling workload and coordinating workload in this model. Data collected from real environment has been analyzed and processed. Results reveal the presence of significant differences between two positions，which is mainly affected by the amount of coordinated flight.

Key words: controller, workload, DORATASK, timeline analysis
