FAA’s AI Reached 22 Control Centers 3 Days Before Nationwide Ground Stop

The Federal Aviation Administration expanded its AI-supported SMART traffic management tool to all 22 air traffic control centers on Nov. 10, 2026, before a nationwide communications disruption grounded flights on Nov. 13. The FAA AI rollout drew scrutiny online, prompting its developer, Air Space Intelligence, to deny responsibility for the stoppage.

The FAA lifted the ground stop Friday night, and domestic flights resumed. Transportation Secretary Sean Duffy attributed the disruption to aging communications infrastructure, while Homeland Security Secretary Markwayne Mullin said officials were investigating what happened.

SMART’s Nationwide Expansion Preceded the Nov. 13 Disruption

What changed when the FAA expanded SMART on Nov. 10?

The agency extended SMART from its initial Washington-area operation to its full network of 22 air traffic control centers. The expansion brought an AI-supported route-planning platform into nationwide use, with the stated purpose of helping controllers anticipate congestion and manage traffic.

The rollout followed an earlier deployment in Washington, D.C., airspace in September. That sequence put the national expansion immediately before Friday’s disruption, drawing public attention to the new software as flights were held across the country.

How did the communications failure affect flights?

Duffy confirmed the nationwide ground stop at 4:16 p.m. ET on Friday. More than 2,000 flights had already been affected when Mashable described the disruption, and flights into the United States were also halted.

In Atlanta air traffic control audio, one controller told pilots, “I’ve been told ground stop everything.” Another transmission referred to “frequency issues in multiple centers,” describing communications trouble extending beyond a single location.

The agency lifted the restriction Friday night. Domestic flights resumed late Friday, ending the nationwide halt that had prompted questions about the newly expanded AI system.

ASI Denies Responsibility for the Ground Stop

What did the SMART supplier say about its integration?

Air Space Intelligence, or ASI, issued a direct denial on X as speculation spread. Its statement addressed both SMART itself and the company’s work integrating its products with the FAA and air traffic control.

“The current ground stop is not based on or a result of the SMART system, any product of ASI or our integration with FAA and ATC,” the company said. Officials had not established a connection between the rollout and the outage.

How did Duffy and Mullin describe the incident?

Duffy focused on the condition of the communications network. He said an old TDM analog system and outdated switches, routers and copper lines had been overwhelmed with data.

Mullin described a telecommunications outage and said there was no indication of a malicious attack. He kept the investigation broad, including examination of whether a cyberattack or artificial intelligence played a role, saying: “You can’t rule out anything at this point.”

The officials’ immediate responses also addressed different tasks: Duffy called for infrastructure investment, while Mullin said investigators would establish what happened and take appropriate action to prevent a recurrence.

How SMART Supports Air Traffic Controllers

Which information does the FAA AI tool analyze?

The FAA describes SMART as a cloud-based platform for evaluating and managing national airspace. An agency fact sheet quoted in the coverage lists airline schedules, weather, airport capacity, airspace conditions and operational constraints among the information it analyzes.

Flight paths, air traffic and controller staffing also feature in descriptions of the system. Those inputs connect expected flight demand with the conditions and resources available to handle it, giving controllers a basis for evaluating traffic flows.

What decisions is SMART designed to support?

The platform predicts traffic flows and identifies potential conflicts before they occur, according to the FAA’s description. It also recommends more efficient routes, supporting controllers as they evaluate how aircraft should move through national airspace.

Its role in the rollout is therefore practical: anticipate where congestion could develop and help staff evaluate route changes. For airlines and passengers, the intended benefit is fewer delays and cancellations, the goal described in the agency’s introduction of the software.

The FAA has cited successful flight rerouting as an early operational result. That application places SMART within the agency’s traffic-management work, where weather, capacity and staffing can all influence route choices.

The SMART Contract Runs for 12 Years

What does the $875 million agreement cover?

The FAA awarded ASI an $875 million, 12-year contract for SMART, according to KCRA. The agreement puts the national deployment within a longer relationship between the agency and its technology supplier.

ASI is an American aerospace and defense company. Its work on SMART supplies the FAA with the cloud-based AI platform now being used to help evaluate airspace and recommend traffic-management changes.

How does the agreement fit into the modernization debate?

The SMART rollout introduces new planning software as Duffy presses for upgrades to older communications equipment. His description of the Friday outage centered on the switches, routers and copper lines supporting air traffic control operations.

That infrastructure became the focus of his funding appeal after the stoppage. Alongside the deployment of a new AI tool, the administration is seeking congressional support to repair and upgrade the systems on which controllers rely.

Earlier FAA Failures and Funding Set the Backdrop

Why did the January 2023 disruption return to attention?

Friday’s stoppage was the first nationwide ground stop since January 2023. The earlier event followed a failure of the FAA’s Notice to Air Missions system, making it the immediate historical comparison for another national interruption.

The November 2026 incident brought communications problems at multiple control centers into focus. Controllers’ references to frequency issues and Duffy’s description of aging equipment gave the latest disruption its own operational context.

Which modernization allocations preceded Friday’s outage?

The Infrastructure Investment and Jobs Act allocated $5 billion to air traffic control, with the money beginning to roll out in 2022. More recently, the One Big Beautiful Bill allocated $12.5 billion to repair and modernize air traffic control systems.

Those measures form the funding backdrop to Duffy’s renewed appeal to Congress. The earlier allocations addressed air traffic control infrastructure, while the SMART agreement established a multiyear contract for the AI-supported traffic-management system.

The chronology stretches from funding beginning to roll out in 2022 to a nationwide AI deployment in November 2026. Friday’s communications failure then prompted the transportation secretary to seek a further investment in the network.

Communications Reliability Drives the Immediate Response

Which equipment did Duffy identify as a problem?

Duffy singled out an old TDM analog system and said outdated network equipment had been overwhelmed with data. His explanation included switches and routers as well as copper lines, placing the problem within the communications infrastructure used by air traffic control.

The controller audio captured the operational effect: instructions to ground flights and references to frequency problems across multiple centers. The nationwide restriction followed communications trouble affecting centers around the country Friday afternoon.

What follow-up did Mullin promise?

Mullin said officials were working through the incident to determine its cause. “We are going through that process and we’re going to find out what happened,” he said, adding that officials would take appropriate action to keep it from happening again.

His comments left the investigation active after the immediate disruption. ASI had issued its denial, Duffy had described infrastructure problems, and investigators were examining possible contributing factors.

Duffy Seeks $50 Billion for Air Traffic Control Upgrades

What action did the transportation secretary ask Congress to take?

Duffy called on Congress to allocate $50 billion to upgrade air traffic control systems. He also pointed to administration initiatives including the Modern Skies Act as he pressed the case for modernization after the outage.

The request would put a new funding decision before Congress following the earlier $5 billion and $12.5 billion allocations. His appeal focused on upgrading the air traffic control system after describing equipment that struggled with the data moving through it.

What developments follow the resumption of flights?

The next steps described by officials are the investigation into the outage, measures to prevent another disruption and the pursuit of modernization funding. Mullin’s stated priority was establishing what happened; Duffy’s was securing investment for upgrades.

For travelers, the immediate operational change came Friday night, when the nationwide ground stop ended and domestic flights resumed. The investigation and funding debate continue beyond that restoration of service.
