Critical NOTAM US air safety system restored after outage The system outage was the latest problem in a difficult week for the US aviation system.
The Federal Aviation Administration’s "Notice to Air Mission," or NOTAM, system was restored on Sunday morning, as the hitch caused the latest difficulty for the US aviation system in the past week.
A critical US aviation warning system that went down on Saturday has been restored, officials said.
US Transportation Secretary Sean Duffy said the system was old and needed an upgrade.
The system went down late on Saturday, prompting the agency to set up a hotline to send notices every 30 minutes with updates to airlines.
