The agency has issued safety directives for both planes. The rollout of 5G has been a big mess in American skies. AT&T and Verizon began deploying the new high-speed cellular network on Jan. 19 while agreeing to create buffer zones around certain airports . The crux of the problem lies in the aircraft''s radar altimeter uses frequencies close to C-band. 5G towers also use C-band radio spectrum frequencies that have the potential to disrupt radar altimeters, an important device on aircraft that informs the pilot of the altitude.

There were concerns some altimeters might not properly filter 5G signals. | Photo by Nicolas Economou/NurPhoto via Getty Images The FAA has announced that an estimated 78 percent of the U.S. commercial fleet have been cleared to land at airports with 5G C-band, even under low-visibility conditions. The agencys statement comes after a week of controversy surrounding the rollout of AT&T and Verizons upgraded cellular tech, which saw US airlines warning of catastrophic disruption to travel and shipping and some international airlines announcing theyd halt flights to some US airports . At issue are concerns that some radio altimeters wont properly ignore signals from the new 5G transmitters.

5G Network Deployment In The US Spawns Cluster Of Disruption Authored by Jon Ostrower via theaircurrent.com (emphasis ours), Something is going on with Runway 10L at Palm Beach International Airport in Florida. Last week, a Bombardier-built CRJ200 regional jet on final approach had the strangest thing happen. The aircrafts radar altitude abruptly ran down to zero, causing repeated loud aural warnings: PULL UP WHOOP WHOOP DONT SINK TOO LOW GEAR . The flight landed without incident in good weather, but it wasnt the first time. Exact same location multiple times the past two weeks, the pilot, who was on the flight deck for both anomalies, told The Air Current . The incidents were reported to the Federal Aviation Administration. Its not known definitively if the radar altimeter behavior was related to pre-deployment testing of 5G telecommunication technologies , but the unexplained incident underscored the fears of aviators, as well as the confusion and increasing disruption that is now befalling U.S. commercial aviation.

The biggest upgrades to wireless phone service are likely to occur over the next few years. For now, T-Mobile US has the biggest network offering 5G.
