FAA Rolls Out AI-Powered Air Traffic Tool at Three Major Airports
The Federal Aviation Administration on Monday launched a new artificial intelligence-powered system at the three major airports serving the Washington, D.C., region, marking the first operational deployment of technology officials hope will eventually reduce flight delays and improve management of U.S. airspace.
Transportation Secretary Sean Duffy has spent months promoting the new technology as one piece of the administration’s effort to modernize the nation’s air traffic control system. FAA Administrator Bryan Bedford said Monday that the Strategic Management of Airspace, Routes and Trajectories system, known as SMART, would provide controllers with “much better decision-making capabilities.”
Both Bedford and Duffy stressed that SMART is intended to assist air traffic personnel rather than take over their jobs. Under the FAA’s system, recommendations generated by SMART are reviewed by agency personnel, who retain authority over whether to act on them.
“There is a lot of conversation about AI and who is controlling the airspace,” Duffy said during a press conference marking the SMART launch, which will be used at Ronald Reagan Washington National Airport, Dulles International Airport and Baltimore/Washington International Airport. “It’s always going to be a human that manages the airspace in America.”
Bedford said he demonstrated the technology for airline CEOs “a few weeks ago,” and that what they saw “opened their eyes about the inefficiencies in the airspace and how much work we’re our controllers to … have to sort out.”
The launch of the advanced AI system came on the same day the FAA found itself grappling with a much older problem: failures involving the aging infrastructure that underpins the country’s air traffic control network.
An equipment failure at an FAA facility in Philadelphia caused major disruptions across the Northeast on Monday. Ground stops and lengthy delays affected Newark Liberty International, John F. Kennedy International and LaGuardia airports after a primary communications circuit failed and officials discovered that a backup fiber-optic line had also been severed.
Bedford said the damaged fiber line represented a “massive” break caused by construction activity between New Brunswick and Newark, New Jersey. Officials initially estimated that repairs could take approximately 13 hours.
Duffy said the fiber had been accidentally cut during construction. The damaged telecommunications lines were eventually repaired, allowing airport operations across the region to begin returning to normal later Monday, though substantial delays remained.
The debut of SMART followed reports that some airline officials initially had reservations about adopting the technology. Subsequent meetings between FAA officials and airline executives, including a September 10 session involving Bedford and airline CEOs, helped address some of those concerns.
During a demonstration at the Transportation Department, Bedford explained that SMART will pull together real-time information to help controllers make better decisions about the movement of aircraft. The FAA says the platform centralizes approximately 200 streams of information, including weather conditions, flight paths, traffic patterns and controller staffing data.
One problem the system is designed to address involves rapidly changing weather. Aircraft can sometimes remain on the ground waiting for action while controllers simultaneously handle dozens of other flights. SMART is intended to analyze changing conditions and provide information that allows decisions to be made earlier.
Bedford said the technology could shorten departure and arrival delays in those situations. It can also identify instances in which multiple aircraft heading to the same airport are projected to arrive at approximately the same time and recommend small changes to their trajectories so their arrivals are better spaced.
“We think we can use better predictive analytics, and we can use the better understanding of how weather is evolving, … and we can make much better airspace decisions,” he said.
Duffy said travelers should begin noticing the effects of the new technology as its use expands, although the benefits will not appear immediately. Officials are looking toward next summer for more visible improvements as SMART is introduced more broadly across the aviation system.
The Washington-area launch will initially serve as a testing period for the technology before the FAA expands SMART to additional parts of the country. The agency says the system will continue operating alongside existing air traffic management technology, with human controllers remaining responsible for the safe separation and movement of aircraft.
