The concept of Trajectory-Based Operations (TBO) is a paradigm shift in air traffic management from traditional clearance-based control to trajectory-based control. It is intended to make flight operations more efficient and predictable, while maintaining operational flexibility. TBO relies on four dimensional trajectories that are managed by specifying a sequence of metering points, each of which is associated with a controlled time of arrival (CTA) that must be met by the aircraft within a specified time tolerance. In this research, we address the design aspects of TBO, such as the optimal number and location of metering points, and their impact on various system performance metrics (e.g., throughput and fuel burn).
