The U.S. Federal Aviation Administration (FAA) said Monday it is proposing to require passenger or cargo aircraft in the United States by early 2024 have 5G C-Band-tolerant radio altimeters or install approved filters.
The proposed airworthiness directive is similar to one that took effect in December 2021, prohibiting passenger and cargo flight operations in the vicinity of 5G C-Band wireless transmitters unless the FAA specifically approved them.
The FAA is also proposing to require airlines to revise airplane flight manuals to prohibit low-visibility landings after June 30 unless the retrofits have been completed on that airplane.
