Abstract
The limited air-to-ground communication methods and tactical operation approaches of the current Air Traffic Control (ATC) system are difficult to satisfy the requirements of Trajectory-Based Operations (TBO) for effectively coordinating the 4-Dimensional Trajectory (4DT) across various systems and stakeholders. To improve the safety, operating economics, and environmental sustainability, a collaborative operational environment is required to share comprehensive information between aircraft and corresponding Air Traffic Management (ATM) components during all flight phases. This paper identifies the concept of connected aircraft, and clarifies approaches for achieving initial TBO by integrating tactical actions and strategic plannings. Furthermore, based on the live flight experiment, the validation of proposed approach to ensure consistency of 4DT between the aircraft and ground systems is presented. Finally, the lessons learned and requirements for cooperating between current ATC systems and SWIM-enabled systems via the connected aircraft are discussed and analyzed.
