Trajectory Management - Surface Tactical Flow

The Trajectory Management - Surface Tactical Flow project is focused on the development of trajectory-based surface operations in support of the Next Generation Air Transportation System (NextGen) initiative. It leverages the development efforts of the National Aeronautics and Space Administration (NASA) Surface Management System (SMS) and provides a road map to the development of a collaborative Surface Traffic Management (STM) system with tools necessary to achieve a fully collaborative surface environment. This environment is required to safely enable the airport capacity necessary for operations in 2025 and to enable trajectory based operations on the airport surface. The NextGen Concept of Operations, authored by the Joint Planning and Development Office (JPDO), states that "4DTs [four-dimensional trajectories] may be used on the airport surface at high-density airports to expedite traffic and schedule active runway crossings." Achieving this vision will require a series of advances in procedures, supporting automation systems, and collaboration between air traffic control (ATC) and the flight operators.
