Completion of Tailored Arrival Manager (TAM) 2 Testing with FAA Tech Center
November 13, 2019

On October 31, 2019, the eco-Demonstrator (ecoD) and Air Traffic Management Exploration (ATM-X) TestBed team successfully completed the second of the ten scheduled “lab shots” in preparation for the ecoD Flight Demonstration scheduled for July 2020. The objective of this test was to generate trajectory-based arrival solutions from NASA’s Tailored Arrival Manager (TAM) and send them electronically to the Data Communication Avionics Lab (DCAL) at the Federal Aviation Administration (FAA) William J. Hughes Technical Center. Data obtained from the FAA’s B737 Max simulator cab during previous TAM-1 testing were played back in the TestBed software platform to create arrival scenarios to Moses Lake, Washington, which is the expected destination for ecoD flights in 2020. For each of five scenarios, conflict-free path solutions were generated by TAM, using NASA’s Autoresolver algorithm, in response to manually set delay values representing time-based metering operations. Once received by the FAA, each TAM solution was converted into a Controller Pilot Data Link Communications (CPDLC) message and loaded into a Flight Management System (FMS) test bench in the DCAL.

Loading TAM solutions into the FMS revealed issues with merging path-stretch route modifications with the aircraft’s nominal route. These issues were debugged and resolved during testing, resulting in successful FMS loads prior to test completion. Test findings were communicated with FAA and Boeing partners and used to establish modified TAM interface requirements for future ecoD testing and flight demonstration.

Urban Air Mobility (UAM) Research Workshop
November 13, 2019

The Air Traffic Management Exploration (ATM-X) UAM sub-project held a UAM research workshop at NASA Langley Research Center, October 29-31, 2019. The UAM sub-project seeks to enable routine airspace access for UAM operations. During the workshop, the Ames and Langley Research Centers team worked towards developing common airspace management concepts, simulation scenarios, and performance metrics for the FY20 focus area: the information exchange requirements and protocols needed for UAM airspace management services to interoperate and support scalable operations. The team will explore both an Unmanned Aircraft Systems Traffic Management (UTM)-like federated concept, and a more centralized concept, and characterize the differences between those two paradigms. The effort will produce reference research technologies and data to guide the UAM community in the design, development, and integration of the UAM airspace system, including in the UAM Grand Challenge (GC). A follow-up workshop is being planned for Spring 2020. (POC: Karl Bilimoria, Lindsay Stevens, David Thipphavong)

The NASA Airspace Technology Demonstration 2 (ATD-2) Team held an FY20 Vision Workshop, October 29-30, 2019 at NASA Ames Research Center. The objectives of the workshop were to discuss current plans and potential future work for FY20, and a general timeline of necessary activities to be completed by the end of the project was shared. Over 60 NASA ATD-2 team members participated in the workshop, which included new additions to the team. Agenda items included a re-cap of last year’s achievements, recognition of team members, a transition plan for the ATD-2 system at Charlotte-Douglas International Airport in North Carolina with the Federal Aviation Administration (FAA) and airline operators, Fuser technology updates, and data-driven capabilities, use cases, and tools. Insights on plans after ATD-2 were also shared by the management team. Further discussions with Tech Leads to add details to the plans are scheduled for December 4-6, 2019. (POC: Al Capps)
