Method and System for Air Traffic Rerouting for Airspace Constraint Resolution

摘要

NASA's National Airspace System Constraint Evaluation and Notification Tool (NASCENT) is a dynamic constraint avoidance system that automatically analyzes routes of aircraft flying, or to be flown, in or near constraint regions, and attempts to find more time- and fuel-effi-cient reroutes around current and predicted constraints. NASCENT provides an evaluation of avoidance routes that saves more than a user-specified number of minutes of wind-corrected flying time savings for all the 20 Air Route Traffic Control Centers (ARTCCs or Centers) in the National Airspace System (NAS) simultaneously. The dynamic constraint avoidance route system continuously analyzes all flights and provides reroute advi- sories that are dynamically updated in real time. This system includes a graphical user interface that allows users to visualize, evaluate, modify if necessary, and implement proposed reroutes.
