The FAA effectively rejected assertions by the wireless industry and the Federal Communications Commission that 5G C-band transmitters can be activated in January as planned without putting aircraft at risk, pledging a cooperative approach to resolving safety concerns while setting the stage for weather delays and cancellations. The agency issued a pair of airworthiness directives (ADs) that take effect December 9 and are likely to limit a wide range of aircraft operations when the new 5G networks are activated, including scheduled passenger and cargo service, emergency response, and medical transportation.
