A United 737-8 operating as Boeing’s ecoDemonstrator Explorer tests next-generation Internet Protocol Suite communications designed to enhance safety, efficiency and airspace capacity

Boeing and United Airlines have completed flight tests of an advanced digital communication system intended to streamline information exchange between the flight deck, air traffic control and airline operations centers. A United 737-8 served as the 2025 Boeing ecoDemonstrator Explorer during the trials.

The two-week test program evaluated Internet Protocol Suite (IPS) standards — internet-based data links expected to improve operational efficiency and flight safety while reducing congestion, fuel burn, operating costs and emissions. Test flights took place in the United States from Houston and in Europe from Edinburgh.

Industry Leaders Highlight Strategic Importance

Boeing Chief Technology Officer Todd Citron called the collaboration a major step toward faster and more reliable digital communication across commercial aviation. United’s 737 Chief Test Pilot Andy McKee emphasized the project’s role in supporting ongoing upgrades to global air traffic management systems.

Part of a Broader Innovation Program

Since 2012, Boeing’s ecoDemonstrator program has tested more than 250 technologies in real operational environments to improve safety, sustainability and overall efficiency.

This year’s IPS testing involved U.S. and European government agencies, aerospace suppliers, communications providers and academic partners. It marks the final phase of a decade-long development effort to prepare the technology for future operational use.
