The FAA launched a new “SMART” AI tool in all air traffic control centers just days before the nationwide ground shutdown.

A new AI-backed air traffic system was deployed to all FAA control centers three days before an extremely rare ground stop brought planes across the United States to a halt on Friday, according to the agency.

The new technology — known as Strategic Airspace Management, or “SMART” — was expanded Tuesday to 22 air traffic control centers across the country, according to the Washington Times.

The tool merges about 200 “data feeds” – focused on flight paths, schedules, weather and other factors – onto a single platform to anticipate airspace constraints and other issues, the outlet reported.

The FAA announced a nationwide ground shutdown at 4 p.m. Friday due to “extraordinary circumstances” and did not immediately link the travel disruptions to the new system.

The shutdown was potentially due to an upgrade to new software, a source told the Post.
