Transportation Secretary Sean Duffy has firmly stated that artificial intelligence (AI) will not replace human air traffic controllers as part of the ongoing modernization of the United States’ air traffic control system. Speaking to CBS News, Duffy emphasized that AI will serve as a supporting tool rather than a substitute for human oversight.
“AI is a tool, but we do not replace humans in how we manage the airspace,” Duffy said. He added, “Am I gonna replace a controller and have AI manage the airspace? The answer to that is hell no, that’s not gonna happen.”
Modernizing Through AI Assistance
The Department of Transportation (DOT) is undertaking a $12.5 billion overhaul authorized by the Bipartisan Infrastructure Law (referred to as the Big Beautiful Bill) to upgrade the country’s air traffic control technology. As part of this effort, AI will be integrated to help controllers optimize flight schedules and reduce delays. Duffy explained that AI-powered software can analyze flight data up to 45 days ahead to suggest minor adjustments in departure times, thereby minimizing congestion and delays.
In addition to AI planning tools, the modernization includes extensive hardware upgrades: nearly half of the copper wiring infrastructure has been replaced, about 270 radio sites upgraded, new surface awareness systems installed at 54 airports to improve ground tracking, and 17 control towers have switched from paper flight strips to electronic versions.
Funding and Safety Imperatives
While the hardware upgrades are underway, the AI software component awaits additional Congressional funding, with projected costs between $6 billion and $10 billion. The Department of Transportation argues this investment is critical given the increasing complexity of managing the busiest airspace in the world.
Duffy referenced recent high-profile incidents, such as last month’s fatal collision at New York City’s LaGuardia Airport, to underline the necessity of enhanced tools to support controllers. “We have human beings navigating, managing the airspace, and as human beings, we can make mistakes,” he said. The use of AI aims to reduce the potential for human error by providing controllers with better data and predictive capabilities.
Why it matters
The modernization of the U.S. air traffic control system is essential for improving safety, efficiency, and capacity in one of the world’s most complex airspaces. While AI has the potential to significantly aid in reducing delays and optimizing flight paths, Secretary Duffy’s comments reassure that human expertise remains central to aviation safety and management decisions.
