Transportation Secretary: FAA Warning System Outage Could Cause Flight Delays

The Federal Aviation Administration (FAA) announced Saturday that a warning system outage could cause flight delays throughout the United States, according to U.S. Secretary of Transportation Sean Duffy.

“The primary NOTAM [Notice to Air Missions] system is experiencing a temporary outage, but there is currently no impact to the National Airspace System because a backup system is in place,” Duffy said in an X post.

“NOTAMs provide updates about anything that may effect the safety of a flight,” Duffy continued. “All active NOTAMs were available until the time of the outage. The agency activated its contingency system to supplement and support preflight briefings and continue flight operations.”

The transportation secretary went on to say, “The [Federal Aviation Administration] is working to fully restore the system, and there may be some residual delays tomorrow morning.”

“Please check with your airline for updates. We are investigating the root cause and we will provide updates,” Duffy added. (Read more from “Transportation Secretary: FAA Warning System Outage Could Cause Flight Delays” HERE)
