The Federal Aviation Administration is giving the aviation industry more time to update legacy radio altimeters that could potentially be impacted by terrestrial 5G operations in C-Band spectrum. In a notice of proposed rulemaking, the FAA said that it remains concerned about the impacts of the C-Band operations on flights, including triggering false warnings from flight systems—particularly as more 5G is deployed across the entire band, and with more than 20 additional operators expected to start operating in the band later this year.
