FAA deeply concerned about 5G network plan on aviation safety

New York: The Federal Aviation Administration (FAA) has raised significant concerns about a plan to use spectrum for 5G wireless networks on aviation safety and is planning to issue a formal warning about the issue, according to a letter.

The aviation industry has voiced alarm about the plan to use C-Band spectrum for more than a year. Network carriers are expected to begin using the spectrum starting December 5 starting in 46 markets.

FAA Deputy Administrator Bradley Mims in a previously unreported October 6 letter said the agency shares "the deep concern about the potential impact to aviation safety resulting from interference to radar altimeter performance from 5G network operations in the C band."

An FAA spokeswoman said on October 29, it "continues to engage with other agencies so that aviation and the newest generation of 5G cellular technology can safely coexist".

The Federal Communications Commission said on October 29, it “remains committed to ensuring air safety as the agency’s successful track record demonstrates, while moving forward with the deployment of new technologies that support American business and consumer needs".

The FAA held a lengthy October 14 meeting with the aviation industry on the issue. FAA and FCC officials have held numerous discussions about the issue, said reports.

The FAA is planning to soon issue a Special Airworthiness Information Bulletin and an airworthiness directive about the issue, according to reports.

The aerospace and airline sector met with the FCC in August, warning without changes "major disruptions to use of the National Airspace System can be expected from the rollout of 5G" and added the FAA will be forced to "drastically reduce aviation operational capacity".

Wireless trade group CTIA said on October 29, 5G networks can safely use C-band spectrum "without causing harmful interference to aviation equipment," and cited numerous active 5G networks using this spectrum band in 40 countries... Any delay in activating this spectrum risks America’s competitiveness."
