A common occurrence in today's National Airspace System (NAS) is the rerouting of aircraft to avoid either bad weather or congested airspace. The FAA is working to obtain a better understanding of the scope of the rerouting problem, and of what improvements can be gained through increased collaboration, between Air Traffic Management (ATM) and airspace users, in the application of reroutes. This report documents the results of Concept Exploration (CE) research on Collaborative Routing performed by the Center for Advanced Aviation System Development (CAASD), of the MITRE Corporation It presents operational needs, a summary of a candidate operational concept, potential benefits, significant technical and operational issues identified, and research and development needs which should be addressed as part of the Concept Development phase for the Collaborative Routing capability.
