Air Traffic Flow and Capacity Management (ATFCM) is a complementary service to ATC. Its objective is to optimize traffic flows based on ATC capacity while ensuring safe and efficient airline operations. DFS Aviation Services offers tailored courses, covering topics such as creating new traffic flow measures, understanding ATFCM systems and tools, clarifying the ATFCM-airport connection, addressing safety hazards, implementing enhanced procedures, and providing certificates of participation to successful participants.
