FAA Prepares to Introduce AI Tool to Support Air Traffic Control Operations

The Federal Aviation Administration (FAA) is preparing to introduce a new AI-powered system to support air traffic control operations in the US. The initial deployment is expected to take place in the Washington, D.C. area before the system is expanded more broadly.

The software, called SMART, stands for Strategic Management of Airspace, Routes, and Trajectories. It was developed by Air Space Intelligence to support air traffic operations.

SMART is intended to help the FAA and airlines respond to operational disruptions by supporting schedule management and helping address delays and cancellations when problems affect flight operations. In its initial stage, the system will function as a decision-support tool, particularly during periods when air traffic operations face disruptions.

The introduction comes as the US aviation sector faces calls to modernize aging infrastructure while continuing to manage air traffic operations and staffing challenges.

Factors Behind Flight Cancellations Across the US

Flight cancellations can occur for several operational reasons. Airline schedules may be affected by aircraft availability, crew scheduling, maintenance requirements, air traffic management, airport capacity, weather conditions, and knock-on effects from earlier disruptions.

Busy hubs such as Chicago O’Hare, Hartsfield-Jackson, and Boston Logan can also experience schedule pressure when earlier delays affect aircraft and crew rotations. A disruption on one service can subsequently influence later departures involving the same aircraft or crew.
