Trajectory Option Set Generation to Support NAS Users during CTOP Events

Concept SEVEN (System Enhancement for Versatile Electronic Negotiation) is a new type of Traffic Management Initiative (TMI) that has been in research and development within the Collaborative Decision Making (CDM) program for years. It allows for the electronic negotiation of routes based on user-submitted preferences when capacity is restricted in an area of the airspace. The first phase of SEVEN, now called the Collaborative Trajectory Options Program (CTOP), will be deployed operationally on November 2011.In this project, Mosaic ATM proposes to develop a decision support tool for NAS users that will allow them to automatically generate the optimal route options and their relative costs during CTOP events. This will allow users to take full advantage of the new capabilities and the opportunities for reducing ground delays and/or fuel burn. Additionally, this capability will be available for integration into NAS simulation tools such as ACES and FACET, to allow NASA to model high-fidelity, realistic user trajectory preferences generally and in response to CTOP TMIs in particular. In Phase 3, Mosaic ATM will additionally provide libraries containing the key algorithms for incorporation into existing flight planning systems.
