The U.S. Congress previously approved $12.5 billion in funding to upgrade air traffic control systems, including billions for replacing communication infrastructure—primarily switching from copper cables to fiber optics. Transportation Secretary Sean Duffy noted the investment focuses on infrastructure upgrades rather than giving competitive advantages to entities like Starlink.

However, the FAA has tested multiple communication technologies, including Starlink, to assess their capabilities and reliability, with approximately 200 companies participating in the evaluations. Starlink publicly stated in March that its service could "partially supplement" aging communication systems but had no intention of fully replacing existing contracts.

This stance reflects the FAA’s cautious approach to safety-critical systems, prioritizing stability and proven technologies while exploring potential supplements. The focus remains on fiber optic upgrades, with satellite services like Starlink yet to secure a role in core aviation communication.
