Boeing and United Airlines have conducted a series of flight tests on a 737-8 aircraft to evaluate a new generation of digital communications designed to improve data exchange between the flight deck, air traffic control, and airline operations centers. The trials were conducted as part of the Boeing ecoDemonstrator Explorer program, to introduce Internet Protocol Suite (IPS) standards that are expected to replace today’s data communication systems.
United’s 737-8, serving as Boeing’s 2025 ecoDemonstrator Explorer, completed two weeks of testing in late October, operating flights from Houston and Edinburgh to assess whether IP-based communication could help reduce delays, optimize flight paths, lower fuel consumption and decrease overall costs and emissions. According to Boeing, the new technology enables faster and more reliable transfer of essential operational information, improving safety and the efficiency of the wider air traffic management system.
United’s Chief Test Pilot for the 737, Andy McKee, emphasized that the project supports modernizing the U.S. air traffic control system and represents an important step toward introducing real-time digital communication into daily operations. Boeing Chief Technology Officer Todd Citron highlighted that the IP standard brings “a significant improvement in reliability and speed of communication between pilots and air traffic control.”
Launched in 2012, the ecoDemonstrator program has already tested more than 250 technologies aimed at improving safety, reducing fuel burn, emissions and noise, and enhancing operational efficiency and the passenger experience. This year’s project brought together a broad group of partners: Collins Aerospace, Honeywell, Thales, SITA, Viasat, the FAA, NASA’s ATM-X project, the European Space Agency (ESA) and Embry-Riddle Aeronautical University.
Technology partners stressed the importance of transitioning to IP-based systems for future operations, especially for trajectory-based operations, which require far greater levels of data exchange than today. ESA noted that this testing moves the industry closer to a unified global solution for air traffic management, one that should bring significant economic and environmental benefits.
Viasat added that the project demonstrates the readiness of satellite communication systems to support the next generation of datalink technologies, which will be essential for managing increasing traffic volumes in a more sustainable airspace.
The test campaign represents the final phase of a decade-long development effort, with these digital communication technologies expected to transition from experimental trials into operational use in the coming years.
