FAA extends AI congestion guidance to all US air traffic centres
The FAA has expanded its AI-based SMART system to all 22 US air traffic control centres, aiming to reduce delays and fuel use by helping controllers manage congestion. Airlines have welcomed the rollout, while the union representing air traffic controllers says it was not involved in designing, testing or implementing the system.
The FAA says SMART has helped reroute 180 flights in the Washington, DC area since 21 September, saving an average of 10 minutes and nearly 80 gallons of fuel per flight. It analyses weather, flight paths, traffic flow and staffing to suggest schedules, routes and arrival order; FAA specialists review its recommendations, and local controllers decide whether to use them. The system cost $875 million, and the agency has not provided details on its impact on passenger flights.
In short
- FAA expands its AI traffic advice system to all 22 US centres.
- The agency reports 180 rerouted flights near Washington, DC.
- Controllers retain control, but their union says it was not consulted.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Expanding SMART could help controllers manage complex, changing traffic conditions by bringing together information on weather, routes, traffic and staffing. The FAA’s reported Washington-area results suggest it may reduce delays and fuel use, while human review and local controllers’ discretion preserve operational judgement.
The case against
A system affecting air traffic decisions should be designed and tested with the expertise of the controllers who use it; the union’s reported lack of involvement raises reasonable questions about whether their practical knowledge and concerns were adequately considered. The reported savings cover a limited set of rerouted flights, passenger impacts have not been detailed, and the $875 million cost makes transparent evidence of wider benefits important.
