SWIM Based Trajectory Coordination to Achieve Strategic Planning and Collaborative Decision Making

抄録

The current Air Traffic Control (ATC) system is heavily reliant on voice communication that is not sufficient to fulfil the requirements of Global Air Traffic Management Operational Concept (GATMOC). To improve the safety, operating economics, and environmental sustainability, the concept of Trajectory-Based Operation (TBO) has been proposed to coalesce the ATM components during tactical, planning and flight operations by coordinating the view of the trajectory between different actors in a collaborative environment. In order to validate the concept and promote the shift from current voice-based operation to TBO, the Multi-Regional TBO Demonstration (MR TBO) project has been conducted by the Federal Aviation Administration (FAA). As a technical supporter of the Japan Civil Aviation Bureau (JCAB), the Electronic Navigation Research Institute (ENRI) developed a SWIM test environment that provides simulation capabilities for demonstrations. In this paper, the observations and analysis of demonstration consisting of scenario discussion and function development for TBO implementation is reported. Moreover, the coordination method and information exchange between SWIM-based services in post-departure phase for how to use managed trajectories is discussed. Finally, the lessons learned and challenges for trajectory sharing, management, and utilization are analyzed.
