FAA eases 5G C-band restrictions but airlines warn of imminent chaos

The Federal Aviation Administration (FAA) has cleared around 45 percent of US commercial planes for low-visibility landings at some airports where 5G C-band will be deployed but airlines have warned that a “catastrophic” aviation crisis is now imminent.

Last week, the FAA issued more than 1,400 warnings to pilots that onboard aviation systems could be disrupted by 5G C-band operations. On Sunday, the agency approved two radio altimeter models that are installed in a wide...

Airlines warn upcoming 5G deployment will interfere with radio altimeters

Airline industry executives have ramped up their warnings that an upcoming type of 5G service will interfere with radio altimeters.

Radio altimeters measure the altitude above the terrain beneath an aircraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft. They are, of course, a key safety feature.

In February, the FCC completed a “C-band” (3.7–3.98 GHz) auction and issued licenses to several wireless network...
