NASA ATD-2 Trajectory Option Set Prototype Capability for Rerouting Departures in Metroplex Airspace

This paper describes NASA’s Airspace Technology Demonstration 2 (ATD-2) Phase 3 prototype capability that is being tested in the North Texas region through summer 2021. For the first time, a shared Decision Support Tool (DST) provides opportunities for participating Flight Operators (FOs) and Air Traffic Controllers (ATCs) to coordinate using a Trajectory Option Set (TOS). When the metroplex airspace is impacted by demand/capacity imbalances, TOS enables departure flights to be rerouted to alternative departure routes with less surface delay.

Surface Meets TOS Update & Potential Future Work

This briefing for the Surface CDM (Collaborative Decision Making) Team (SCT) & Flow Evaluation Team (FET) discussed the foundational data/information quality needs to enable a collaborative TOS concept that includes surface. The primary goal of this briefing was on soliciting broad feedback from the operator community. This discusses the importance of the Earliest Off Block Time (EOBT) as a predictor for improving NAS demand predictions as well as possible areas where SCT/FET could contribute to uses of Trajectory Option Sets in future FAA systems.
