New Regulations Ensure Safe Coexistence With Upper C-Band Wireless Services
The Federal Aviation Administration (FAA) has announced new regulations requiring all radio altimeter systems on aircraft operating in the 48 contiguous United States and the District of Columbia to meet minimum performance requirements. The regulations aim to ensure safe coexistence with Upper C-band wireless services, which are expected to be implemented in the near future. Aircraft operating under part 121 must comply with the new regulations by December 30, 2030, while other aircraft with radio altimeters must comply by October 31, 2034. The FAA’s decision was reported in the Federal Register, and the new regulations are expected to have significant implications for the aviation industry.
