There were widespread concerns that the new 5G technology would cause disruption with some of the devices and modules for aircrafts at low visibility levels. Carriers such as Verizon and AT&T are growing massively in the 5G world, so it raises an eyebrow with regards to how aircrafts will adjust (or not) to this new development.
Since then, the FAA cleared a couple of aircrafts to fly at these levels albeit the concerns. They have lifted restrictions on nearly 50% of the commercial fleet, and made half of the impacted runways eligible for low visibility landings.
“Even with these new approvals, flights at some airports may still be affected,” the FAA stated in regards to these new procedures. “The FAA also continues to work with manufacturers to understand how radar altimeter data is used in other flight control systems.”
Some of the restrictions are easing up and could continue this track when 5G technology becomes more common.
