The US warns that 5G networks can generate interference and divert flight paths; Fahm – 07/12/2021

The US Federal Aviation Administration (FAA) warned on Tuesday that interference from spectrum use from 5G network to be launched into the country poses a safety risk and may result in a flight diversion.

The aviation industry and the Federal Aviation Administration have raised concerns about potential interference from 5G networks in sensitive aircraft electronics such as radio altimeters. AT&T and Verizon agreed to delay the commercial launch of their 5G C-Band service until January 5, after the Federal Aviation Administration raised concerns.

The Federal Aviation Administration (FAA) issued airworthiness guidance, and requested a review of flight manuals to prohibit certain operations that require radio altimeter data when 5G Band C signals are present.

Under FAA guidelines, the “unsafe condition” represented by planned spectrum use requires immediate action prior to deployment because radio altimeter anomalies that are not detected by aircraft automation or the pilot, particularly near the ground, can affect flights and landings. .

The Federal Aviation Administration (FAA) confirmed Tuesday that it believes “5G network expansion and aviation will coexist safely.” The two added guides “provide a framework and gather more information to avoid potential impacts on aviation safety equipment.”

The agency is continuing discussions with the Federal Communications Commission, the White House and industry executives about the fine lines of any restrictions, which are expected to be outlined in the coming weeks in a series of notifications.

AT&T and Verizon said in November they would take measures to limit interference for at least six months, but airline industry groups said they were insufficient to address air safety concerns.

Telecommunications groups argue that there are no aviation safety issues in other countries that use the frequency spectrum.
