The system outage was the latest problem in a difficult week for the US aviation system. A critical US aviation warning system that went down on Saturday has been restored, officials said. 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. 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.

The NOTAM system provides pilots, flight crews and other users of US airspace with critical safety notices. It could include items such as taxiway lights being out at an airport, nearby parachute activity or a specific runway being closed for construction. US Transportation Secretary Sean Duffy said the system was old and needed an upgrade. "There was minimal disruption," Duffy told CNN's "State of the Union" program. "There's a process in place right now to get this system fixed. We want to expedite that and get this new system in place. This is an old system that needs to be upgraded.".
