As the Federal Communications Commission nears a planned expansion of radio frequencies available to 5G cellular networks, U.S. aviation industry leaders are expressing concerns about potential safety issues linked to radio (radar) altimeter performance.
Aviation and Wireless Industries Clash Over Looming 5G C-band Changes
Key Takeaways:
- U.S. aviation industry leaders and the FAA are deeply concerned that the FCC's planned expansion of 5G cellular networks into the C-band, set for December 5, could cause harmful interference with aircraft radio altimeters, jeopardizing flight safety.
- Aviation stakeholders, including major aerospace companies and pilot associations, warn that interference could lead to severe outcomes such as missed approaches, flight delays, diversions, and even runway closures, urging collaborative solutions.
- Conversely, the FCC and the wireless industry (CTIA) assert that C-band 5G is safe for aviation, citing a lack of reported interference in similar global deployments and questioning the data supporting aviation's claims.
- The FAA is actively engaging with other agencies and is reportedly preparing to issue a Special Airworthiness Information Bulletin and an airworthiness directive to address the potential impact.
