Flights of large unmanned vehicles like the Ikhana have traditionally required a following safety chase aircraft as they travel through the same airspace used by commercial aircraft. The Ikhana flew in accordance with the Federal Aviation Administration’s (FAA’s) Technical Standard Order 211 -- Detect and Avoid Systems -- and Technical Standard Order 212 -- Air-to-Air Radar for Traffic Surveillance. The NASA UAS-NAS Project team contributed to the development of the Detect and Avoid standards used by this test flight.

On June 28, 2018, ATD-3 team members Dr. Kapil Sheth (ARC, Flight Trajectory Dynamics and Controls Branch) and Mr. David Wing (LaRC, Crew Systems and Avionics Operations Branch) briefed approximately 20 DAL personnel to present an overview of the ATD-3 subproject, as well as demonstrations of ground- and cockpit-based reroute technologies, NASCENT and TAP, respectively. NASCENT (National Airspace System Constraint Evaluation and Notification Tool) is a ground-based tool for airline air traffic control (ATC) Coordinators and dispatchers to identify time- and fuel-saving route changes, while accounting for airspace and weather constraints. NASCENT route changes can be implemented for single- or multi-flight advisories. TAP (Traffic Aware Planner) is an onboard tool for flight crews to implement TASAR (Traffic Aware Strategic Aircrew Requests), a means for optimizing an aircraft’s route leveraging onboard software, and onboard platforms with connectivity to avionics and external data sources. TAP and NASCENT are also able to be connected with each other through data sharing, a feature of interest to Delta Air Lines. DAL is in the process of investing in connectivity solutions within the aircraft and between air and ground. As a result of NASA’s briefing, DAL has expressed interest in collaboration and/or tech transfer opportunities with NASA to implement and expand ATD-3 capabilities, including integration with other DAL systems, such as their Flight Weather Viewer tool for pilots. A follow-on meeting is planned within the next 1-2 months to explore all ATD technologies and further opportunities for engagement. (POC: Kapil Sheth) + Back to Top
