Sean Duffy proposes big plans to upgrade air traffic control systems, use AI to find ‘hot spots’

Transportation Secretary Sean Duffy announced plans to bolster airport air traffic control systems with the latest technology over the next four years, while also using artificial intelligence (AI) to identify “hot spots” where close encounters between aircraft occur frequently.

The announcement came after an update on an investigation into a crash near Ronald Reagan Washington National Airport in Arlington, Virginia, when a U.S. Army helicopter and an American Airlines-operated passenger jet collided over the Potomac River Jan. 29.

“We’re here because 67 souls lost their lives on Jan. 29,” Duffy told reporters Tuesday, noting that the National Transportation Safety Board (NTSB) unveiled its preliminary findings into the crash earlier in the day.

The findings noted that, over the last 2½ years, there have been 85 near misses or close calls at Reagan National. Close calls were identified as incidents when there are less than 200 feet of vertical separation and 1,500 feet of lateral separation between aircraft.

Appearing shocked at the findings, Duffy questioned how the Federal Aviation Administration (FAA) did not know about the “hot spot,” where near misses happen frequently.

“We’re having near misses, and if we don’t change our way, we’re going to lose lives,” he said. “That wasn’t done. Maybe there was a focus on something other than safety, but in this administration, we are focusing on safety.”

The FAA has deployed AI tools to sift through data and find additional hot spots in U.S. airspace near airports to find similar situations to what has been happening at Reagan National.

Once the hot spots are identified, Duffy’s team will implement changes to reduce the close encounters between aircraft.

Duffy also said he has learned that air traffic control systems across the country are 25 to 30 years old, and some of them even use floppy disks as if they were stuck in the 1980s.

While the system is antiquated, the secretary stressed it was safe. Despite the system being safe, Duffy said it needs to be upgraded.

“This should have happened four years ago, 10 years ago, 15 years ago,” he said. “But, right now, we’re at a point where we can actually do it. And we can do it really fast.”

Duffy said the task could take up to four years to complete.

The job entails bringing in a brand-new air traffic control system, switching from copper wires to a combination of fiber, wireless and satellite systems.

The current radar system from the 1970s or early 1980s works, but Duffy wants to put state-of-the-art radar in place and terminals with the right screens and the best technology.

“We’re going to deploy resources for runway safety — new technology that will allow our air traffic controllers not to use binoculars in the tower to see where aircraft are at, but to actually have ground radar sensors at our airports that will allow air traffic controllers to see where airplanes are at,” he said. 

“We’ve heard a lot of new stories of just near misses on the tarmac. And how do you alleviate that? Take away the binoculars and give them technology so they can see on their screens where every aircraft is located.

“By doing this, we are going to greatly improve our safety in the system.” 

Technology, on the other hand, is not cheap, which the secretary acknowledged.

In an environment in which the Department of Government Efficiency is looking for ways to cut costs and save money, Duffy explained making upgrades in the name of safety is worth the investment.

Over the next couple of weeks, Duffy said, he plans to introduce his plan to Congress and take in their feedback.

Once he goes through the feedback, Duffy said he plans to return to Congress and ask for the money up front to expedite the process of upgrading the air traffic control systems.

“It’s not that the FAA didn’t want to do the upgrades,” he said. “It just takes too long. So, they have to give us the money. We’re going to later lay out our plan to actually do it really quickly.”
