Air Traffic Control Officers (ATCOs) play a central role in maintaining safety and efficiency of air traffic operations. Thus, education and training of ATCO trainees is an important issue in ATC domain. However, efficient skill transfer from experienced ATCOs to trainees is difficult because ATCOs often utilize practical knowledge in their work. Therefore, towards supporting education and training of ATCO trainees, the present research evaluates the applicability of a process visualization interface of ATC tasks called COMPASi (COMPAS in interactive mode / COMPAS: COgnitive system Model for simulating Projection-based behavior of Air traffic controller in dynamic Situations) for visualizing ATCO's practical knowledge involved in their control strategies, i.e., sets of control activities and their timings. Through a simulation-based experiment using a complex traffic scenario including various kinds of ATC tasks and wind effect, COMPASi was confirmed to have a capability of visualizing performance differences of two types of control strategies from viewpoints of task efficiency and preventive risk reduction. Performance comparison of control strategies under various traffic and wind conditions, which is achieved by COMPASi, is expected to support trainees in comprehensive understanding of ATCO's practical knowledge.
