US airlines warn C-Band 5G could cause 'catastrophic disruption'

The airline industry claims a “catastrophic” event could unfold on Wednesday when AT&T and Verizon activate their new C-Band 5G networks. In a letter obtained by Reuters, the CEOs of several prominent passenger and cargo airlines, including Delta, United and Southwest, warn interference from 5G cell towers could affect the sensitive safety equipment on their planes.%7B

"Unless our major hubs are cleared to fly, the vast majority of the traveling and shipping public will essentially be grounded," they state in the letter, which was sent to the heads of the White House Economic Council, Federal Aviation Administration and Federal Communications Commission, as well as Transportation Secretary Pete Buttigieg. "Immediate intervention is needed to avoid significant operational disruption to air passengers, shippers, supply chain and delivery of needed medical supplies."

The airlines have asked that AT&T and Verizon not offer 5G service within 2 miles of some of the country’s busiest and most vital airports. They’re also urging the federal government to ensure “5G is deployed except when towers are too close to airport runways until the FAA can determine how that can be safely accomplished without catastrophic disruption." The agency established 5G buffer zones at 50 airports on January 7th. 

The letter is the latest development in the ongoing back and forth between the airline and wireless industries. AT&T, T-Mobile and Verizon spent nearly $80 billion at the start of 2021 to secure the repurposed C-Band spectrum the FCC had put up for auction. In November, AT&T and Verizon agreed to delay their C-Band rollouts to January 5th to help the FAA address any interference concerns. They later proposed limiting the power output of cell towers close to airports and agreed to a further two-week delay on January 4th.

It seems much more serious on the Boeing aircraft than on the Airbus aircraft.

From what I understand, both manufacturers have IAP restrictions due to 5G but, the Boeing aircraft have additional issues with the thrust reversers and some flight controls which are triggered by the Rad Alt on some models.  On the Airbus side the Landing gear needs to be compressed to trigger those systems.

Mobile firms agree another 5G delay at US airports

By Jonathan Josephs
Business reporter, BBC News

46 minutes ago

US mobile networks AT&T and Verizon have agreed to postpone the rollout of their new 5G service at some airports.

The C-band service, which offers faster speeds and broader coverage, was due to be turned on tomorrow.

But airlines in the US have pushed to delay the start, warning that the signals could interfere with aeroplane navigation systems.

The telecoms firms expressed frustration as they bowed to pressure to limit their rollout.

AT&T said it was "temporarily" deferring the rollout at a "limited number of towers around certain airport runways". Regulators had had "two years" to plan for the start of 5G service, it added.

"We are frustrated by the Federal Aviation Administration's inability to do what nearly 40 countries have done, which is to safely deploy 5G technology without disrupting aviation services, and we urge it do so in a timely manner," AT&T said in a statement.

"We are launching our advanced 5G services everywhere else as planned with the temporary exception of this limited number of towers."

Verizon also said it had "voluntarily decided to limit our 5G network around airports".

This third postponement came as the White House and aviation authorities rushed to work out a solution to an issue that airlines have warned could cause major disruption, forcing them to ground some of their fleets and cancel flights.

Airlines fear C-band 5G signals will disrupt planes' navigation systems, particularly those used in bad weather. Two major planemakers, Airbus and Boeing, have also voiced concerns.


In a recent letter to regulators, the 10 biggest US airlines said they wanted 5G signals to be excluded from "the approximate two miles of airport runways at affected airports as defined by the FAA on 19 January 2022".

"This will allow 5G to be deployed while avoiding harmful impacts on the aviation industry, travelling public, supply chain, vaccine distribution, our workforce and broader economy.


"We further ask that the FAA immediately identify those base stations closest to key airport runways that need to be addressed to ensure safety and avoid disruption," they added.

White House spokeswoman Jen Psaki said officials were working on a solution that "maintains the highest level of safety while minimising disruptions to passenger travel".

The much-hyped expansion of 5G networks in the US has been chaotic, to say the least.

The rollout has been delayed twice - and now AT&T and Verizon have bowed to intense pressure, agreeing to defer opening some parts of the network near airports.

This happened because of concerns about the safety of aircraft. To mitigate those concerns, airlines would have had to operate under restrictions they clearly found intolerable.

But those safety issues have been well publicised for more than a year. There was clearly time to come up with a mitigation plan - and other countries have been able to do just that.

The question is, why were US regulators, telecoms operators, airlines and airports apparently unable to come up with a workable solution?


Phone companies have spent tens of billions of dollars to upgrade their networks to deploy the 5G technology, which brings much faster internet services and greater connectivity.

In other countries, telecoms companies have been required to reduce 5G signals around airports by taking steps such as pointing antennae away from control towers.

But US firms were not expecting those types of limits to be imposed when they spent billions on 5G infrastructure, said Diana Furchtgott-Roth, a professor of transportation economics at George Washington University and a former deputy assistant secretary at the US Department of Transportation.

"They want to get the most out of their investment," she said. "What they should have been told beforehand is that they would not have free reign to use it because it could interfere with the planes but they were not given that information in advance."

There have been several delays already because of the aviation concerns, with launch dates in December and earlier this month both being pushed back. Wireless industry groups say airlines are distorting the risks.

In an update on Sunday, the FAA, which oversees aviation safety across the US, said it had cleared "an estimated 45% of the US commercial fleet to perform low-visibility landings at many of the airports where 5G C-band will be deployed".

The FAA added that it had approved "two radio altimeter models that are installed in a wide variety of Boeing and Airbus planes".

"Even with these new approvals, flights at some airports may still be affected," the regulator said.

"The FAA also continues to work with manufacturers to understand how radar altimeter data is used in other flight control systems. Passengers should check with their airlines if weather is forecast at a destination where 5G interference is possible."

Dubai's Emirates suspends flights to several U.S. destinations on 5G concerns

CAIRO (Reuters) - Dubai's Emirates airline announced on Tuesday that it will suspend flights to several destinations in the United States as of Jan. 19 until further notice because of concerns over 5G mobile deployment.

The move is "due to operational concerns associated with the planned deployment of 5G mobile network services in the U.S.", the company said. It said the destinations include Boston, Chicago, Dallas Fort Worth, Houston, Miami, Newark, Orlando, San Francisco, and Seattle.

Emirates flights to New York's JFK, Los Angeles International Airport and Washington DC's Dulles International Airport will continue to operate as usual, the company added.

"We are working closely with aircraft manufacturers and the relevant authorities to alleviate operational concerns, and we hope to resume our US services as soon as possible," the carrier said.

The White House said earlier on Tuesday that it wants to reach a solution on 5G deployment that protects air safety while minimizing disruption to air travel.

Here's why 5G is so concerning for U.S. airlines, and what Canada has done to fix it

The emergence of 5G technology has raised some red flags for airlines in the United States.

The cellphone technology, capable of producing laser-fast mobile internet speeds, can interfere with some sensitive aircraft technology, which the airlines worry could produce severe disruptions or even crashes. While most aircraft technology is unaffected, 5G can disrupt an aircraft’s altimeter, which indicates how high a plane is in the air relative to the Earth below. The altimeter is also used in automated landings.

Altimeters operate at frequencies close to the new C band 5G wireless, set to launch in the U.S. on Wednesday. Disruptions to this technology -- in a worst-case scenario – can lead to runway crashes or collisions with mountains. More realistically, any bad weather could cause significant delays as pilots would need to conduct visual landings without the help of the altimeter.

These networks also have the potential to disrupt helicopters and air ambulance services, along with some military and police operations, according to Canada’s Department of Innovation, Science, and Economic Development (ISED).

U.S. airlines have been adamant that Verizon and AT&T – the two major 5G carriers in the U.S. -- should slow down the launch of the new service surrounding the country’s airports, warning that thousands of planes may be grounded or delayed if the rollout continues.

“Immediate intervention is needed to avoid significant operational disruption to air passengers, shippers, supply chain and delivery of needed medical supplies. The harm that will result from deployment on January 19 is substantially worse than we originally anticipated,” Airlines for America, which represents eight major U.S. airlines and two major shipping companies, wrote in an open letter on Monday.

“The ripple effects across both passenger and cargo operations, our workforce and the broader economy are simply incalculable. Every one of the passenger and cargo carriers will be struggling to get people, shipments, planes and crews where they need to be. To be blunt, the nation’s commerce will grind to a halt.”

Airlines for America has asked that 5G service be halted in the two miles surrounding 50 of the U.S. top airports. On Tuesday, AT&T and Verizon announced it would postpone the launch of 5G service near some U.S. airports for six months and would work with regulators and the aviation industry to come up with a solution, but are moving forward with their launch everywhere else on Jan. 19.

WHAT HAS CANADA DONE TO ADDRESS THE ISSUE?While the U.S. is launching its 5G this week, Canadian companies have offered 5G to customers since early 2020 and airline disruption has not been a major concern. But why?The answer is two-fold: Canada doesn’t offer 5G networks at the speed the U.S. is set to launch, and Canada has already taken several measures to help keep airlines safe.While the U.S. is about to launch 5G in the 4.2 to 4.4 gigahertz range, Canada’s latest spectrum auction was only for speeds of up to 3.7 gigahertz, which means Canada’s mobile internet is slower, but doesn’t come as close to the range that would interfere with airplane technology.Some 40 countries have already launched 5G, but the U.S. is among the few to launch in the higher range. The European Union set standards for up to 3.8 gigahertz in 2019, for example.Additionally, Canada has already addressed concerns regarding 5G’s impact on aircraft. In Nov. 2021, the ISED restricted 5G services by creating “exclusion zones” in the areas surrounding Canadian airports and required that 5G antennas be tilted downward to avoid interference with aircraft. “ISED and Transport Canada are working with both the telecommunications and aviation industries to ensure that appropriate rules are in place to protect the critical operations of radio altimeters,” a spokesperson for Transport Canada wrote in an email to CTVNews.ca.“These technical rules are designed to ensure that 5G is deployed in a manner that minimizes the potential for interference to radio altimeters.”Additionally, Transport Canada has issued several recommendations for all pilots who use altimeters, including to avoid the use of automated landing or takeoff procedures in areas not covered in these exclusion zones and to avoid the use of night vision goggles without external lighting to avoid relying on the altimeter.Transport Canada also suggests that all 5G-connected devices need to either turned off or set to airplane mode and only 3G or 4G networks should be used in the event of an emergency.

AT&T, Verizon pause some new 5G after airlines raise alarm

AT&T and Verizon will delay launching new wireless service near key airports after the nation’s largest airlines said the service would interfere with aircraft technology and cause widespread flight disruptions.

The decision from the companies came Tuesday as the Biden administration intervened to broker tried to broker a settlement between the telecoms and airlines over a rollout of new 5G service.

The companies said they will launch 5G or fifth-generation service Wednesday, but they will delay turning on 5G cell towers within a 2-mile radius of runways designated by federal officials. They did not say how long they would keep those towers idle.

President Joe Biden said the decision by AT&T and Verizon “will avoid potentially devastating disruptions to passenger travel, cargo operations, and our economic recovery, while allowing more than 90% of wireless tower deployment to occur as scheduled.” He said the administration will keep working on a permanent solution.


Even with the concession by the telecommunications companies, federal officials said there could be some cancellations and delays because of limitations of equipment on certain planes. Delta Air Lines also said there could be issues with flights operating in bad weather because of airport restrictions that regulators issued last week, when the 5G rollout appeared to be on schedule.

The new high-speed wireless service uses a segment of the radio spectrum that is close to that used by altimeters, which are devices that measure the height of aircraft above the ground. Altimeters are used to help pilots land when visibility is poor, and they link to other systems on planes.

AT&T and Verizon say their equipment will not interfere with aircraft electronics, and that the technology is being safely used in 40 other countries.

However, the CEOs of 10 passenger and cargo airlines including American, Delta, United and Southwest say that 5G will be more disruptive than earlier thought. That is because dozens of large airports were subject to flight restrictions announced last week by the Federal Aviation Administration if 5G service was deployed nearby. The CEOs added that those restrictions wouldn’t be limited to times when visibility is poor.

“Unless our major hubs are cleared to fly, the vast majority of the traveling and shipping public will essentially be grounded. This means that on a day like yesterday, more than 1,100 flights and 100,000 passengers would be subjected to cancellations, diversions or delays,” the CEOs said in a letter Monday to federal officials. “To be blunt, the nation’s commerce will grind to a halt.”

The showdown between the airline and telecom industries and their rival regulators — the FAA and the Federal Communications Commission, which oversees radio spectrum — threatened to further disrupt the aviation industry, which has been hammered by the pandemic for nearly two years.

This was a crisis that was years in the making.

The airlines and the FAA say that they have tried to raise alarms about potential interference from 5G C-Band but the FCC ignored them.

The telecoms, the FCC and their supporters argue that C-Band and aircraft altimeters operate far enough apart on the radio spectrum to avoid interference. They also say that the aviation industry has known about C-Band technology for several years but did nothing to prepare — airlines chose not to upgrade altimeters that might be subject to interference, and the FAA failed to begin surveying equipment on planes until the last few weeks.

Randall Berry, a professor of electrical and computer engineering at Northwestern University, likened the interference issue to two stations that overlap on the radio dial. The FCC-determined separation “may be be enough for some (altimeters) but not for others,” he said.

One solution could be outfitting all altimeters with good filters against interference, Berry said, although there could be a fight over who pays for that work — airlines or telecom companies.

After rival T-Mobile got what is called mid-band spectrum from its acquisition of Sprint, AT&T and Verizon spent tens of billions of dollars for C-Band spectrum in a government auction run by the FCC to shore up their own mid-band needs, then spent billions more to build out new networks that they planned to launch in early December.

In response to concern by the airlines, however, they initially agreed to delay the service until early January.

Late on New Year’s Eve, Transportation Secretary Pete Buttigieg and FAA Administrator Stephen Dickson asked the companies for another delay, warning of “unacceptable disruption” to air service.

AT&T CEO John Stankey and Verizon CEO Hans Vestberg rejected the request in a letter that had a scolding, even mocking tone. But they had second thoughts after intervention that reached the White House. The CEOs agreed to the second, shorter delay but implied that there would be no more compromises.

In that deal, the telecoms agreed to reduce the power of their networks near 50 airports for six months, similar to wireless restrictions in France. In exchange, the FAA and the Transportation Department promised not to further oppose the rollout of 5G C-Band.

Biden praised that deal too, but the airlines weren’t satisfied with the agreement, regarding it as a victory for the telecoms that didn’t adequately address their concerns.

Airlines worldwide rush to change flights over U.S. 5G dispute

Issue appears to affect the Boeing 777, used by carriers around the world

The Associated Press · Posted: Jan 19, 2022 3:28 AM ET | Last Updated: 4 hours ago

Airlines across the world, including the long-haul carrier Emirates, rushed Wednesday to cancel or change flights heading into the U.S. over an ongoing dispute about the rollout of 5G mobile phone technology near American airports.

The issue appeared to impact the Boeing 777, a long-range, wide-body aircraft used by carriers across the world. Two Japanese airlines directly named the aircraft as being particularly affected by the 5G signals as they announced cancellations and changes to their schedules.


Dubai-based Emirates, a key carrier for East-West travel, announced it would halt flights to Boston, Chicago, Dallas-Fort Worth, Houston, Miami, Newark, New Jersey, Orlando, Florida, San Francisco and Seattle over the issue beginning Wednesday. It said it would continue flights to Los Angeles, New York and Washington.

In its announcement, Emirates cited the cancellations as necessary due to "operational concerns associated with the planned deployment of 5G mobile network services in the U.S. at certain airports."

"We are working closely with aircraft manufacturers and the relevant authorities to alleviate operational concerns, and we hope to resume our U.S. services as soon as possible," the state-owned airline said.

Potential interference with aircraft altimeters

The United Arab Emirates successfully rolled out 5G coverage all around its airports without incident. But in the U.S., the Federal Aviation Administration worries that the C-Band strand of 5G could interfere with aviation equipment.

Of particular concern in the 5G rollout appears to be the Boeing 777, a major workhorse for Emirates.

Japan's All Nippon Airways Co. Ltd. said in a statement that the FAA "has indicated that radio waves from the 5G wireless service may interfere with aircraft altimeters." Altimeters measure how high a plane is in the sky, a crucial piece of equipment for flying.

"Boeing has announced flight restrictions on all airlines operating the Boeing 777 aircraft, and we have cancelled or changed the aircraft for some flights to/from the U.S. based on the announcement by Boeing," ANA said.

Japan Airlines Co. Ltd. similarly said that it had been informed that 5G signals "may interfere with the radio altimeter installed on the Boeing 777."

"We will refrain from using this model on the continental United States line until we can confirm its safety and we regret to inform you that we will cancel the flight for which the aircraft cannot be changed to the Boeing 787," the airline said.

The U.S. aviation regulator, the FAA, came to a last-minute deal to avoid turning dozens of airports into no-fly zones for certain planes, but the bigger issue about whether 5G could interfere with airplanes' ability to land remains unresolved. 2:04

Chicago-based Boeing Co. did not immediately respond to a request for comment.

Air India also announced on Twitter it would cancel flights to Chicago, Newark, New York and San Francisco "due to deployment of the 5G communications" equipment. It said it would try to use other aircraft on U.S. routes as well.

The cancellations come even after mobile phone carriers AT&T and Verizon will postpone new wireless service near some U.S. airports planned for this week.

The FAA will allow planes with accurate, reliable altimeters to operate around high-power 5G. But planes with older altimeters will not be allowed to make landings under low-visibility conditions.

Military may take months to gauge 5G safety risks to aircraftMilitary may take months to gauge 5G safety risks to aircraft

 Jan 19, 08:33 PM

WASHINGTON — As the commercial airline and telecommunications industries scramble to limit the potential safety risks to aircraft from a rollout of new 5G networks, it may be months before the U.S. military has a handle on whether, or how big, of a problem this might be for its own planes.

At the center of the controversy is whether the deployment of 5G networks, operating along a frequency known as the C-band, will interfere with radar altimeters used by military, civilian and commercial aircraft and helicopters. These altimeters are used to measure the distance between the aircraft and the ground.


For the military, they are particularly necessary when mobility aircraft such as cargo planes or tankers land in adverse weather conditions. If the pilot’s visibility is poor during such a landing, he or she would have to use altimeters to measure how far off the ground the aircraft is during the approach, and a flawed reading could lead to a crash.

Verizon and AT&T began activating their 5G networks on Wednesday, promising much faster wireless service speeds than the previous 4G network. But amid a growing outcry from the commercial airline industry, the companies on Tuesday announced they would temporarily limit the deployment of new 5G networks near some airports. Some international airlines announced plans to cancel certain flights to the United States over the concern.hat 5G deployment could cause interference to civil and military aircraft.

The Federal Communications Commission in early 2021 auctioned off the rights to operate 5G transmissions in the C-band, or 3.7-3.98 GHz, primarily to Verizon and AT&T. That is close to the 4.2-4.4 GHz spectrum radar altimeters use. The airline industry trade association Airlines for America said it has brought concerns about the potential for interference and safety risks to the FCC several times since 2018, to little avail.


The Air Line Pilots Association said in a Jan. 18 statement interference from 5G networks operating on this spectrum could cause aircraft to lose their radar altitude information or mistakenly tell the pilots the wrong altitudes, and could lead to crashes.

In a Jan. 17 letter to Transportation Secretary Pete Buttigieg, Federal Aviation Administration head Stephen Dickson, FCC chairwoman Jessica Rosenworcel and the White House, Airlines for America urged that the new 5G networks not be activated within two miles of major airports. Failing to do so could result in “significant operational disruption to air passengers, shippers, supply chain and delivery of needed medical supplies,” reads the letter, which was also signed by the heads of major commercial aviation firms such as American Airlines, Delta Airlines, UPS and FedEx Express.

The military decided about a year ago that instead of trying to block the auction of the C-band spectrum, it would work to limit the potential interference with its aircraft’s systems.

In a Tuesday email, Air Force spokesman Capt. Patrick Gargan said the Defense Department is working with its FAA counterparts on the 5G issue.


Gargan said the Pentagon stood up a “Joint Interagency FiveG Radar Altimeter Interference,” or JI-FRAI, team, to develop “quick reaction tests” to determine the impact of 5G on avionics.

More than a dozen commercial aviation groups are warning that the sale of spectrum could lead to interference and even fatalities.
By Valerie Insinna and Aaron Mehta

But those tests will not provide any answers soon. Gargan said testing is scheduled to begin this month, and the results are expected late this summer.

Gargan also said military services have issued bulletins to the field and to fleets to alert aircrews about the potential for interference, and is setting up a system for reporting interference if it happens.

The Air Force, Verizon and AT&T did not respond by press time on whether the telecommunications companies would similarly limit 5G rollout around military bases where aircraft take off or land.


Honeywell, one of the leading manufacturers of radar altimeters, told Defense News it hasn’t been asked to take any steps to further safeguard its altimeters, though it continues working with the government and aircraft manufacturers on this issue.

“Honeywell’s radar altimeters meet all existing FAA and manufacturer certification requirements,” Honeywell spokesman Adam Kress said in an email. “Neither the agency nor manufacturers have provided any additional requirements for our equipment. If needed, we’re ready to verify compatibility of our equipment with any new requirements and we have been working with the FAA, Department of Defense and aircraft manufacturers to conduct testing of our systems in the 5G spectrum.”

The Air Force Safety Center said it had received no reports of problems with 5G interference, although the 5G networks on the C-band spectrum had only started to come online.

CNBC reported some other forms of 5G have previously been available to some Verizon, AT&T and T-Mobile customers. Those 5G services, however, are not on the C-band, which is prized for its ability to travel long distances and transmit large amounts of data.

The president of Emirates says the 5G rollout that led to flights being canceled is 'one of the most delinquent, utterly irresponsible' situations he's witnessed

 Schwarz/AFP via Getty Images%7B

  • The president of Emirates lashed out at US 5G rollout plans.
  • Tim Clark told CNN it was "one of the most delinquent, utterly irresponsible issues" he'd seen in his career.
  • Airlines including Emirates and British Airways canceled flights over 5G safety concerns.

The president of Emirates has slammed a 5G rollout plan in the US that prompted airlines to cancel flights.


"This is one of the most delinquent, utterly irresponsible issues, subjects, call it what you like, I've seen in my aviation career," Emirates President Tim Clark told CNN Wednesday.

His comments came after Dubai-based Emirates and other airlines announced Tuesday they would suspend flights to some US airports over safety concerns linked to a 5G rollout near airports. Verizon and AT&T agreed last-minute on Tuesday that they would delay the launch of 5G service near airports after airlines warned the technology could cause massive flight disruptions.

Despite the pause of the rollout, some airlines – including Emirates – continued to suspend flights. 

Clark told CNN that 5G was being deployed differently in the US compared to other countries, and that Emirates wasn't aware until Tuesday morning of "the extent that it was going to compromise the safety of operation of our aircraft and just about every other 777 operator." He added that Emirates decided to suspend the flights "until we had clarity."

Many of the aircraft used on the affected routes are Boeing 777 airplanes. The Federal Aviation Administration Sunday published a list of Boeing and Airbus aircraft whose radio altimeter models were approved for performing low-visibility landings at many of the US airports where the 5G rollouts were due to take place. The 777 aircraft was not included in the January 16 list, although some 777 models have been included on updated lists.

Emirates said Tuesday that from Wednesday it was suspending flights to six of its 12 US passenger destinations and was switching another three routes from Boeing 777 planes to Airbus A380s "due to operational concerns associated with the planned deployment of 5G mobile network services." It said that this was based on Federal Aviation Administration advice and guidance from Boeing.

Emirates said Thursday that the FAA and Boeing had changed their guidance and that it would resume the canceled routes Friday and switch the A380s back to 777s Saturday.

Airlines including Air India, Japan Airlines, All Nippon Airways, and British Airways also suspended some flights over the 5G rollout.

Ten major US air carriers had warned federal officials in a letter Monday that the scheduled 5G deployment could "potentially strand tens of thousands of Americans overseas" and grind the nation's commerce "to a halt."

This is because it could affect the aircraft's radio altimeter, which is used to determine a plane's altitude above ground level when landing or flying above mountainous terrain.

Verizon and AT&T said Tuesday they would continue with the rollout on Wednesday as planned but would voluntarily delay deploying the technology near airports. Both criticized the FAA, with an AT&T spokesperson telling Insider that the company was "frustrated by the FAA's inability to do what nearly 40 countries have done, which is to safely deploy 5G technology without disrupting aviation services."

Alaska Airlines cancels nearly 25 flights out of Paine Field due to 5G restrictions

KOMO News Staff  4 hrs ago

EVERETT, Wash. – Alaska Airlines canceled nearly 25 flights Monday at Everett’s Paine Field because of 5G.

The airline confirmed 23 flights into and out of Paine Field were canceled because FAA restrictions mean the Embraer E175 airplane can not land in poor weather or low visibility because 5G could possibly interfere with systems.

This plane is flown by Alaska Airlines’ sister carrier Horizon Air and partner SkyWest. Alaska Airlines did confirm there could be more cancellations, delays or diversions at airports where there is low visibility.

The company did say there is a flexible travel policy in effect for those impacted.

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.

The document also covers 747-8 passenger variants. Boeing 747-400s and classic models are not covered.

Altogether there are about 336 aircraft under U.S. registry and 1,714 worldwide that are impacted by the rule, according to the FAA.

UPS Airlines (NYSE: UPS) operates 22 747-8 freighters, according to a fact sheet on its website. Atlas Air (NASDAQ: AAWW), the largest 747 operator in the world, has 10 747-8 cargo jets in its fleet, along with 14 777s. FedEx (NYSE: FDX) has 51 777 freighters, its latest quarterly report shows. Privately held Kalitta Air operates four 777s. DHL Express has 19 777s in its fleet, according to Planespotters.


United Airlines (NASDAQ: UAL) also has a large 777 fleet that has helped the carrier produce record cargo revenue during the pandemic as it works to restore full passenger service.

It’s not immediately clear whether the carriers will face any tangible operational problems. Spokespeople at Atlas, FedEx and UPS directed all 5G inquiries to Airlines for America, an industry lobbying group that declined to comment on the new airworthiness directive.

The three carriers could collectively experience up to 10,800 flight delays, diversions or cancellations per year at a cost of $800 million if 5G is rolled out without mitigating steps, the association said several weeks ago.

Radio altimeters are instruments that send out signals to precisely measure the distance to the ground or water and relay the information to multiple onboard systems. Overlapping signals can degrade its function, aviation experts say.

AT&T and Verizon launched fifth-generation (5G) wireless broadband service in 46 markets on Jan. 19 using frequencies in the C-band radio spectrum, but delayed turning on base stations near airports after the airline industry warned the White House of potential flight delays and cancellations to maintain safety.

Since the agreement, the FAA cleared more than three-quarters of the U.S. commercial fleet to perform low-visibility landings at airports where wireless companies deployed 5G towers, saying they were not vulnerable to interference. A new 2-mile safety buffer around airports in 5G markets further expanded the number of airports available to planes with previously cleared altimeters.


The FAA issued the new airworthiness directive after an evaluation by Boeing that many systems on the 747-8s and 777s, including the autothrottle, ground proximity warning and thrust reversers, rely on the altimeter. The evaluation followed an FAA directive in December calling for precautions in low-visibility conditions.

Detour Lake becomes the first mine in Canada to have a private 5G network


Detour Lake mine, located in northeast Ontario, is the first mining operation in the country to be connected to a private 5G wireless network, thanks to a partnership between the mine’s operator Kirkland Lake Gold and Rogers.

Detour Lake is the second-largest gold-producing mine in Canada, and the partnership will offer enhanced coverage, reliability, and low latency. It will also help turn it into a “smart mine.”

“Bringing a 5G wireless private network to Detour Lake provides the stable and reliable service we need as we build the digital mine of the future,” Tony Makuch, president and CEO of Kirkland Lake Gold, said in a statement.

“Not only does the new network provide an extra layer of connectivity for our employees, it also enables us to drive mining innovation and technology into the future by expanding tele-remote drill operations and research into potential autonomous haul trucks.”

Rogers has deployed five wireless towers at the mine with a built-in backup system, helping to provide reliable access across the mine’s 80 square kilometres.

The connection will also help employees access real-time information on operations, use drones to deliver supplies at the bottom of the mine, and further explore their work.

The two companies are also collaborating on eight new cell towers along Highway 652 that will primarily be off the grid. Seven of the towers will largely be fueled by wind and solar energy. The project will cover a total stretch of 180 km between Cochrane, Ontario and Detour Lake and is set to be complete by the summer of 2022.

FAA Statements on 5G

Friday, January 28, 2022

Visit our 5G and Aviation Safety page for more information.

Through continued technical collaboration, the FAA, Verizon, and AT&T have agreed on steps that will enable more aircraft to safely use key airports while also enabling more towers to deploy 5G service. The FAA appreciates the strong communication and collaborative approach with wireless companies, which have provided more precise data about the exact location of wireless transmitters and supported more thorough analysis of how 5G C-band signals interact with sensitive aircraft instruments. The FAA used this data to determine that it is possible to safely and more precisely map the size and shape of the areas around airports where 5G signals are mitigated, shrinking the areas where wireless operators are deferring their antenna activations. This will enable the wireless providers to safely turn on more towers as they deploy new 5G service in major markets across the United States. The FAA continues to work with helicopter operators and others in the aviation community to ensure they can safely operate in areas of current and planned 5G deployment.
