Flights throughout the United States could experience “residual delays” Sunday morning while the Federal Aviation Administration (FAA) works to restore a critical warning system that faced an outage the night before, Secretary of Transportation Sean Duffy said on Feb. 1.
“The primary NOTAM 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 wrote in a post on social media platform X, adding that the FAA has activated a contingency system to “supplement and support preflight briefings and continue flight operations.”
