FAA threatens more 5G disruptions

Verizon and AT&T agreed in June to a variety of restrictions and service delays to allow owners of aircraft with susceptible altimeters the chance to replace or modify them, Russ Niles reports for AVWeb.

WASHINGTON - The FAA is threatening more 5G-related flight disruptions if federal communications officials don’t throttle the signals of smaller cellphone carriers around airports, Russ Niles reports for AVWebContinue reading original article.

The Military & Aerospace Electronics take:

28 October 2022 - According to Vox, nearly 90 million 5G devices have been shipped in the U.S. Fifth-generation (5G) technology is more than 10 times faster than previous gen speeds. The C-band frequency used by 5G operates between 3.7 and 3.98GHz.

Reuters, who broke this newest 5G story, obtained a letter dated 21 October 2022 in which Acting FAA Administrator Billy Nolen cited industry data established "aviation safety would be compromised if the U.S. government does not codify certain additional operating limits in the 5G C-Band environment."

The concerns stem from 5G affecting aircraft altimeters which could prove disastrous if a pilot needed to land without a visual approach. Nolan's letter noted that if the Federal Communications Commission mitigates the risk to altimeters, the "FAA would be forced to take immediate steps to ensure the safety of the traveling public, raising the likelihood of flight disruptions across the United States."
