On March 4, 2020, NASA’s Airspace Technology Demonstration 2 (ATD-2) researchers participated in the Aerobahn Terminal Flight Data Manager (TFDM) Planning Workshop, hosted by Saab Sensis Corporation in Syracuse, New York. The goal of the Workshop was to bring together the future TFDM users identified by the Federal Aviation Administration’s (FAA’s) early TFDM implementation waterfall, including major airlines (American, United, Delta, Southwest) and airports (Charlotte, San Francisco, Seattle, New York), and provide updates on the user tool and solicit feedback. Currently, Saab Sensis is developing a tool powered by their Aerobahn product to provide users with an interface to communicate with TFDM. The interface includes submitting an airline’s Earliest Off-Block Times (EOBTs) and substitution requests for surface metering programs, and display of Target Off-Block Times (TOBTs) and Target Movement Area Entry Times (TMATs) generated by TFDM. Workshop participants discussed TFDM functionality to be used as well as roles and responsibilities during a surface metering program to prepare for the implementation of the program at their sites. ATD-2, a precursor to TFDM, is currently under operational evaluation at Charlotte Douglas International Airport (CLT) facilities, including the FAA air traffic control (ATC) Tower and American Airlines Ramp Tower since September 2017. ATD-2 researchers shared experiences and lessons learned from the field demonstration. The next workshop is currently scheduled for June 2020, hosted by the Port Authority of New York and New Jersey (PANYNJ).
