Was America's Nationwide Grounding of Aircraft Caused By Its New AI System?

America's nationwide grounding of flights on Friday happened "amid growing scrutiny... of a new AI-powered air traffic management system" deployed by America's Federal Aviation Administration, reports Texas news station KXAN. Ironically, the system is called SMART — but the outage happened "following warnings" from members of the U.S. Congress about this new AI system's safety, reliability and oversight: In an Oct. 13 letter to the Government Accountability Office, more than 20 members of Congress requested an independent review of the FAA's development and implementation of its Strategic Management of Airspace, Routes and Trajectories system, known as SMART. The lawmakers questioned whether the technology was being deployed with adequate input from frontline air traffic controllers, sufficient training and appropriate safety evaluations... In their letter to the GAO, the lawmakers specifically questioned whether the FAA had adequately evaluated risks associated with SMART's artificial intelligence capabilities, including the potential for the technology to interfere with experienced controllers' decision-making or generate inaccurate safety-critical information. "The nation's frontline aviation safety workforce apparently had little to no input into SMART's development and have received limited training and information during the current deployment process," the lawmakers wrote. The letter also questioned the FAA's decision to initially pilot the technology in heavily congested airspace, including the National Capital Region. "Our switches, our routers, actually got overloaded with data," U.S. Transportation Secretary Sean Duffy acknowledged Friday. But an article from The Hill.com notes that Duffy also said the new AI tool had nothing to do with the ground stop, and that he said the system "isn't plugged in." "This is completely disconnected, and I love that some people have said this would be the root cause. By the way, if it was, I'll tell you that, but this is not even plugged in," he said. "So, there's no possible way SMART would have impacted." Duffy also asked Congress for $50 billion to rebuild what he described as an "incredibly old" air traffic control system. Duffy had posted the day before that the AI system had been at least partially rolled out and that it was already working (adding "Soon this technology is going NATIONWIDE") And Friday CNN's aviation analyst said they believed that AI system could be connected to the nationwide outage, calling it "a tremendous amount of coincidence," according to a report from Mediaite: CNN Aviation Analyst: "Many times in the past, what we have seen, and this has gone back decades, is that because air traffic control is this piecemeal, mishmash of a whole bunch of different systems... some going back to radio, telephones and floppy disks... when they put in new computer systems, they often have difficulty talking with, communicating with, or working with the much older systems. And I have to say, it's a tremendous amount of coincidence... If they're putting in new software now, this new SMART system to start managing that, and now we have a communications outage, I'm — we've seen this so many times in the past. I don't know if they're linked, but it's just too much coincidence that they were trying to start that moving today, and now we have problems with the en route system. So if I was to guess — and we haven't heard any, you know, it's not that it's threats or criminals or terrorists. We haven't heard anything like that. So I am guessing that once again we have a problem with new air traffic control computer systems, AI — you know, modern systems trying to communicate with old systems. And we have just seen this so many times in the past, and it's a big problem... Our whole national airspace system is you know, pieces and parts. It's kind of a Franken-system. And that would be my guess, that they are having computer issues by putting the new software in with the old, just because today they announced that that were going to do this new system. KXAN describes some of the complexity of the newly-launched AI system: According to the FAA, the system consolidates approximately 200 data streams, including airline schedules, flight paths, weather patterns, airport capacity, airspace conditions and air traffic controller staffing metrics. The agency says SMART uses artificial intelligence to analyze that information, predict traffic flows, identify potential conflicts and recommend adjustments to flight routes and departure schedules before disruptions occur. The FAA describes the technology as a shift from a reactive approach to a predictive one, allowing aviation officials to identify congestion, weather-related restrictions and other operational problems hours, days or even weeks in advance... The congressional letter raised questions about whether the FAA's implementation strategy was moving faster than its safety evaluations, workforce training and independent oversight could support. Ironically, the article points out that the FAA promoted anticipated benefits from the technology including fewer delays and flight cancellations. (Other anticipated benefits included improved on-time performance and faster recovery from weather disruptions.) Although the FAA has realized one of the system's anticipated benefits: reduced fuel consumption.
