ATD-2 Stormy 2021 Tabletop Exercises with Flight Operators in North Texas
November 25, 2020

The NASA Airspace Technology Demonstration 2 (ATD-2) team conducted virtual Tabletop/Training exercises with American Airlines and Southwest Airlines, on October 6 and November 16, 2020, respectively, utilizing remote connections to the ATD-2 system. The Tabletop exercises augment hands-on and video-training previously provided, and were designed to simulate the flight operators use of the Trajectory Options Set (TOS) technology that is imbedded in the ATD-2 system. Realistic traffic and weather scenarios were simulated which resulted in the flight operators assessing reroute opportunities to reduce delay. The ATD-2 team used the opportunities created by the simulations to reinforce important aspects of the ATD-2 system, including elements of the system that provide accurate and timely information to assist in making the most informed and beneficial reroute decisions. Additionally, the flight operators provided valuable insights to the ATD-2 team regarding the coordination required when assessing and submitting a reroute. Future Tabletop sessions are planned with Envoy Airlines and subsequent sessions with American and Southwest airlines and the Air Traffic facilities.

ATM-X CTM Sub-Project Discuss Upper Class E Traffic Management (ETM) in the 4th Federal Unmanned Aircraft Systems (UAS) workshop
November 25, 2020

The Air Traffic Management Exploration (ATM-X) Project’s Collaborative Traffic Management (CTM) sub-project discussed their work on Upper Class E Traffic Management (ETM), at the US Geological Survey (USGS) National Innovation Center-hosted, fourth Federal Unmanned Aircraft Systems (UAS) workshop on November 17-19, 2020. The purpose of the event was to: “showcase progress reports from Federal partners, new technology capabilities going forward in industry, standardization efforts, and growing the domestic UAS industry with Defense Innovation Unit.” During the Emerging New Technology track, the CTM team presented an overview of the ETM research and development currently underway. Other presentations included updates on development and testing from four High Altitude Long Endurance (HALE) aircraft companies. The combination of these presentations and the maturity of platforms highlighted the importance of the work that is in progress to develop an airspace management approach to Upper Class E airspace.

ATD-2 Phase 3 Update for Collaborative Decision-Making General Session
November 25, 2020

The Airspace Technology Demonstration 2 (ATD-2) Field Demo Partners provided an update on the Phase 3 Field Demonstration at the 2020 Collaborative Decision Making (CDM) Annual General Session meeting on November 17, 2020. CDM is a joint government/industry initiative aimed at improving air traffic flow management through increased information exchange among aviation community stakeholders. Two CDM Teams (Surface CDM Team and Flow Evaluation Team) have a joint task to work with NASA to facilitate the transfer of ATD-2 knowledge and technology. These two teams include representatives from most US air carriers (cargo and freight), business aviation, several major airports, academia, and the Federal Aviation Administration (FAA). The ATD-2 update included accomplishments from the past year and outlined steps being taken to ensure maximum impact from an FY 2021 project extension that was granted due to the impact of COVID-19.

Other topics covered included a shift in strategy for training from in-person to a 100% virtual training environment starting in March of 2020, and the development of tailored online training videos and material for each field facility. Collaborative tabletop exercises are being conducted with the airline operators as an additional training tool and to gain a greater understanding of decision-making and internal coordination processes required to submit Trajectory Option Set (TOS) reroutes. New TOS metrics including the aggregate system level benefits and the probability of delay savings exceeding the relative trajectory cost, were presented, highlighting the increased number of use cases that these metrics will enable. Additionally, the introduction of a new use case extending the TOS concept from the origin departure airport all the way to the downstream arrival airport was outlined. The briefing also described NASA’s strategy for developing and transferring a suite of machine learning microservices that embody the core capabilities of the ATD-2 Surface Trajectory Based Operations surface model. The machine learning services will form the building blocks of a scalable NAS-wide TOS Digital Reroute capability and are intended to be transferred to the aviation community (e.g., industry and FAA).
