System Enhancements for Versatile Electronic Negotiation

NextGen concept for managing en route congestion with dynamic Trajectory-Based Operations

System Enhancements for Versatile Electronic Negotiation (SEVEN) is a NextGen concept for managing en route congestion and enabling National Airspace System (NAS) customers to submit cost weighted sets of alternative trajectory options for their flights. SEVEN provides traffic managers with a tool that algorithmically considers customer trajectory costs, as it assigns reroutes and delays to flights subject to traffic flow constraints. This concept will reduce traffic manager workload and allow more control over traffic in uncertain weather situations. SEVEN also gives NAS customers greater flexibility to operate flights according business priorities, using Trajectory-Based Operations (TBO).

One of the most significant SEVEN benefits is the ability to recapture system capacity, currently lost due to severe weather or other capacity limiting factors.. Presently, the Collaborative Decision Making (CDM) Future Concepts Team (FCT) is evaluating SEVEN through a series of storyboards, simulations utilizing Integrated Simulation Environment (ISE) and Human-In-The-Loop (HITL) exercises with aviation stakeholders, as a part of the Concept Engineering and Development (CED) process.
