ATD-2 Reaches Over One Million Gallons of Jet Fuel and 150,000 Urban Trees Savings at Charlotte Douglas International Airport
May 19, 2021

Benefits totals from Phases 1 and 2 of the ATD-2 field demonstration at Charlotte Douglas International Airport (September 29, 2017 through May 16, 2021.) Saved 1,015,734 gallons of fuel. Saved 21,398,666 pounds of carbon dioxide, which is equivalent to 159,119 urban trees. Saved 5,527 hours of engine run time. Reduced delay by 837.6 hours. Saving passengers an estimated $5.3 billion in value of time and crew costs. Prototype of FAA TFDM system which will be installed at Nation's 27 busiest airports.
Summary of ATD-2 benefits up to May 16, 2021

On May 16, 2021, NASA’s Airspace Technology Demonstration 2 (ATD-2) Phase 1 and 2 field demonstration at Charlotte Douglas International Airport (CLT), achieved a cumulative savings of one million gallons of jet fuel, since September 2017. The field demonstration has been conducted in collaboration with American Airlines and the Federal Aviation Administration (FAA) Air Traffic Control (ATC) facilities. The fuel savings are the result of ATD-2 Integrated Arrival, Departure, and Surface (IADS) system recommended actions, such as holding departures at gates with engines off through surface metering during peak traffic periods, pre-scheduling the approval request (APREQ) flights at gates, as well as renegotiating the release times of APREQ flights while taxiing through electronic coordination between the IADS system and the FAA’s Time Based Flow Management (TBFM)/Integrated Departure Arrival Capability (IDAC) which eliminates verbal communication between CLT Tower and En Route Centers. Additionally, the field demonstration IADS system has reduced 21.4 million pounds of CO2 emissions which is equivalent to planting over 159,000 urban trees based on formulae developed by the US Environmental Protection Agency (EPA). CLT flight operators also saved 5,527 hours of engine run time, and over one million dollars in crew costs. The detailed calculations and additional operational benefits are described in the figure above.

ATM-X Extensible Traffic Management (xTM) Sub-Project Joint Briefing on the Status of the UAS Traffic Management (UTM) Pilot Program (UPP) Phase 2 Effort to CTIA
May 19, 2021

The ATM-X Extensible Traffic Management (xTM) sub-project manager briefed the status of the Unmanned Aircraft Systems (UAS) Traffic Management (UTM) Pilot Program (UPP) Phase 2 effort to CTIA, in a joint presentation with the Federal Aviation Administration (FAA), on May 12, 2021. (The CTIA is an advocacy group representing the US wireless communications industry.) UPP is an important component of the FAA’s UTM implementation process. A UPP Phase 1 demonstration in Summer 2019 successfully demonstrated an information-sharing network for UAS operating below 400 feet, in a collaboration between NASA, the FAA, and industry partners. UPP Phase 2 flight activities were completed in Fall 2020, with demonstrations of the FAA Flight Information Management System (FIMS) prototype and infrastructure, new technologies and data to validate the latest ASTM standards for Remote Identification and UAS Service Supplier interoperability, and UAS Volume Reservations to notify drone operators of emergencies and ensure other UTM capabilities are integrated appropriately. UPP Phase 2 also evaluated secure information exchanges between the FAA, industry, and authorized users for ensuring data integrity. The CTIA audiences commended the dedication and creativity of the UPP Phase 2 team for safely overcoming the COVID-19 challenges while preparing and conducting field tests. The UPP effort was supported by NASA’s UTM project and later the ATM-X project. A potential follow-on UPP event is under consideration.

ATM-X xTM Sub-Project Upper Class E Traffic Management (ETM) Team Meets with the Montana Space Grant Consortium (MTSGC)
May 19, 2021

The ATM-X xTM Sub-Project Upper Class E Traffic Management (ETM) Team met with the assistant director of the Montana Space Grant Consortium (MTSGC), an affiliate of NASA's National Space Grant College and Fellowship Project. In 2017, MTSGC led a nationwide eclipse ballooning campaign ( during the total solar eclipse. In this campaign, students conducted balloon flights from over 25 locations across the eclipse path, from Oregon to South Carolina, and live videos and images from the near-space flights were sent to NASA to show on the website. Proposals are being submitted to conduct a similar campaign during 2023 annular and 2024 total solar eclipses, and the ETM team and MTSGC discussed potential ways for collaboration. The parties agreed to discuss further potential collaboration and an appropriate agreement process.
