In a letter sent Monday to United States transportation and economic officials and obtained by NBC News, the CEOs of major carriers said that the launch could ground flights and leave "tens of thousands of Americans" stranded overseas.
The warning came ahead of Wednesday's rollout of the new C-Band 5G service from telecommunications giants AT&T and Verizon. It also comes as airlines continue to contend with the fallout from widespread flight cancellations fueled by the spread of the omicron variant of Covid-19 and a series of winter storms that caused travel chaos across the U.S.
The airlines warned that the 5G signals risked interfering with safety equipment pilots rely on to take off and land in inclement weather.
“Unless our major hubs are cleared to fly, the vast majority of the traveling and shipping public will essentially be grounded,” they said in the letter, which was signed by the chief executives of American Airlines, United Airlines, Delta Air Lines, Southwest Airlines and Jet Blue, along with leaders of UPS and FedEx.edit on 18-1-2022 by putnam6 because: (no reason given)

What’s 5G got to do with airplanes? Not much, argue the wireless carriers hoping to deploy the technology. But the FAA says it’s worried that C-band could interfere with some radio altimeters, aircraft safety tools that rely on nearby airwaves. The agency is so concerned that it’s been fighting to delay 5G deployment and has prepared guidance that could cause flight cancellations from airports operating near certain 5G antennas, meaning that anyone who flies or has one of these devices could be affected.

Well, that brings up another aspect why is no other nation's air industry showing the concern we are seeing from the US carriers? Makes it even more suspect in my opinion.

I feel like the timing is a little suspect, in that they've been talking about the 5G rollout for years now. I assumed it was already live in major cities.
it's a little hard to believe the people who build these planes and emergency systems hadn't heard about it, and looked into it. To interfere it has to be using similar frequencies, which have been public information for a few years now.
It almost feels like theres one big effort to bring the US to a halt, and every big corporation is in on it.
The Federal Communications Commission (FCC) published the rules for 5G transmission in the 3.7 GHz to 3.98 GHz band (also known as C-band) in March 2021, which included a 220 MHz guard band around aviation operations (twice the industry’s requested amount) as well as phased rollout for additional testing. At the 11th hour, the Federal Aviation Administration (FAA) made a public cry, claiming that altimeters are vulnerable to 5G transmissions.
The FAA asserts, “The U.S. airspace is the most complex in the world… Aviation in the U.S. is the safest in the world. That’s because we rely on data to mitigate risk..” However, the FAA’s data did not consist of actual aviation tests performed at airports with 5G base stations as was done in Japan, Norway, France, and other countries. Instead the FAA hired an organization to create a predictive model of the worst-case scenarios of 5G transmissions at high power levels with obsolete altimeters. While such a model could be helpful to supplement real-world tests, the FAA based its decision on a laboratory model and refused to make the underlying data available to independent researchers for review. Richard Bennett, co-inventor of Wi-Fi, called the FAA’s model a hazard analysis, not a risk assessment.

Control ? But as stated it has to do with bad weather taking off and landing. Actually I'm beginning to fear flying internationally to America lately.

Only if it's from Huawey.

It’s Time For The U.S. To Let 5G In The C-Band Take Off
I found this part interesting:

During this year’s holiday travel season, over 50 million people will jet off to their destination. Upon boarding their flights, passengers won’t be greeted with Jingle Bells, but an announcement prompting them to turn their cellphones off once the cabin door closes. Why? Because using a cell phone may interfere with a plane’s navigation and communications equipment. This equipment operates on internationally designated spectrum bands that allow for interference-free communications, and with new technologies hitting the market, including an abundance of 5G mobile devices, the risk of interference may be growing.
Without proper testing from industry or the Federal Communications Commission (FCC) in coordination with the Federal Aviation Administration (FAA), the safety of such devices – and air travel – is up in the air.
Spectrum is a finite resource, meaning that there is only so much available for use by the industries who need it, and developers of new technologies are seeking access to additional spectrum bands to support the benefits of the future 5G. This has led the FCC to look at opening up spectrum bands previously allocated to other services to support the rollout of 5G technologies. But while certain spectrum bands can be safely shared when a particular product does not use up the entirety of its band that is allocated or each product is designed for sharing, that is not always the case.
