FAA system that alerts pilots and other flight personnel about hazards or any changes to airport facility services and relevant procedures was not processing updated information, the civil aviation regulator’s website showed.
The FAA said it is working to restore its Notice to Air Missions System.
“United States FAA working to restore its Notice to Air Missions System. We are performing final validation checks and reloading the system now. Operations across the National Airspace System are affected,” US Federal Aviation Administration said on Twitter.

The failure has so far resulted in some 700 cancelled flights across the US. The FAA has ordered airlines to pause all domestic departures until 9 am Eastern Time to allow the agency to validate the integrity of flight and safety information.
Transportation Secretary Pete Buttigieg said in a tweet that he is in touch with the FAA and monitoring the situation.
Meanwhile, the Air Traffic Control System Command Center (ATCSCC) also issued an advisory that the United States NOTAM system failed and since then no new amendments have been processed.
“The United States NOTAM system failed at 2028Z. Since then no new NOTAMS or amendments have been processed. Technicians are currently working to restore the system and there is no estimate for restoration or service at this time,” the ATCSCC advisory read.
United Airlines said it had temporarily delayed all domestic flights and it would issue an update when it learned more from the FAA.
“Arriving and departing passengers can expect delays this morning and throughout the day,” Austin-Bergstrom International Airport said on Twitter.
