FedEx, UPS operate large Boeing freighters FAA says vulnerable to 5G - American Shipper

A new Federal Aviation Administration regulation prohibiting Boeing 747-8 freighters and all 777 widebody aircraft from landing at airports where 5G towers might interfere with onboard safety equipment could have a disproportionate impact on major cargo airlines like UPS, FedEx and Atlas Air.

The airworthiness directive issued Tuesday said the FAA has identified an additional hazard from interference with radio altimeters beyond creating a landing danger in low-visibility conditions. Specifically, the signal interference could result in altimeters delivering faulty data to flight computers that control the aircraft’s pitch and put it in an inappropriate “up-down” position regardless of weather conditions, which is “especially hazardous” at low altitude.

Other systems could also be compromised, which combined with the uncommanded, inappropriate pitch inputs, “could affect the flightcrew’s ability to accomplish continued safe flight and landing,” the directive said.
