NASA collaborated with the Federal Aviation Administration (FAA) and Boeing in a simulation known as the Tailored Arrival Manager (TAM) 5B, on May 27, 2020. The simulation, part of preparations for the eco Demonstrator (ecoD) flight demonstration involving NASA’s Tailored Arrival Manager, was successfully completed with only Boeing having physical access to laboratory facilities due to COVID-19 restrictions. The NASA team remotely operated systems in the Aviation Systems Division’s TestBed lab to generate TAM solutions using periodic input data from a B787 simulator and Flight Management System (FMS) in Boeing’s Integrated Aircraft Systems Laboratory (IASL). With the FAA unable to access their data communications laboratory in New Jersey, TAM trajectory solutions were relayed manually to the Boeing flight deck.

TAM-5B marked the first opportunity to integrate with real-world avionics representing a B787, which was recently confirmed by Boeing as the aircraft type for the ecoD 2020 flight. Key accomplishments of the test included the acquisition of 1 Hz track data representing Automatic Dependent Surveillance-Broadcast (ADS-B) and the verification of coordinate transformations performed by the FAA in translating TAM solutions into Controller-Pilot Datalink Communications (CPDLC) messages.

ADS-B-like data from the B787 relied on Boeing sending data to the FAA using a simulation data exchange standard known as Test and Training and Enabling Architecture (TENA). Upon receiving TENA data from Boeing, the FAA’s Target Generation Facility (TGF) formatted the data into track messages and sent them to TAM via TestBed. This data interface with TestBed can conceivably be used to acquire ADS-B data from any live flight in the National Airspace System (NAS). The availability ADS-B data for ecoD flights – the first expected in August 2020 – will provide an additional source of aircraft position and velocity in the event of data contingencies.
