A critical Federal Aviation Authority (FAA) system has suffered a glitch, grounding flights across the US according to media reports. The FAA posted an advisory notice early Wednesday which notes that the United States NOTAM (Notice to Air Mission) system has āfailedā and that engineers are working to bring it back online.
At 7:19AM ET, the agency said it had āordered airlines to pause all domestic departuresā until 9AM ET to give it time to āvalidate the integrity of flight and safety information.ā At least one airline, United, issued a notice prior to the latest FAA directive saying itās grounded all flights. The FAAās grounding was subsequently extended to 9:30AM ET.
āThe FAA is working to restore its Notice to Air Missions System,ā the FAA said in an earlier statement. āWe are performing final validation checks and repopulating the system now. Operations across the National Airspace System are affected.ā It added that it will provide āfrequent updatesā as work progresses.
NOTAM is a critical system that keeps pilots and other flight personnel informed of the status of airports across the country, Reuters reports. It can offer information on runway closures, bird hazards, and other obstacles.
As of this writing, flight tracker FlightAware reports over a thousand delayed flights in the US, and over 100 cancelled.
Update January 11th, 7:28AM ET: Added FAA statement saying itās grounded all flights until 9AM ET.
Update January 11th, 8:12AM ET: Added FAA extending the grounding until 9:30AM ET.
