As the volume of flight is extended, it is expected that the task complexity of air traffic controllers will increase. In Japan, air traffic control in en-route airspace is operating with TEPS (Trajectorized En-route Traffic Data Processing System), which has functions to display information necessary for air traffic controllers’ tasks. It has evolved to support the controllers with less workload, resulting in escalated interaction between controllers. However, paradoxically this means more information is provided and more workload would be required. In order to manage mental workload of air traffic controllers, detailed analyses of their tasks with TEPS are needed. In this study, we tried to develop a model of the air traffic control tasks conducted on TEPS by applying the Multilevel Flow Model (MFM). Based on the model, we clarified the task structure in which several controllers participated and assess contributing factors in workload.
