FAA says 5G could impact radio altimeters on most Boeing 737s

From Reuters:

“U.S. regulators are warning that 5G wireless operations could affect radio altimeters in most Boeing 737 aircraft and impact crew workload and airplane landings, according to a government notice posted online on Wednesday.

The Federal Aviation Administration’s directive affects Boeing’s 737s, except its -200 and -200C series, the Federal Register notice said.

It added that their “radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band).”
