All Flights ‘Grounded Across US’ After Major System Failure


All flights in the United States (US) have been grounded due to a system failure, reports on Wednesday showed. The Federal Aviation Administration (FAA) has reportedly suffered a nationwide system error.

The FAA system alerts pilots and other flight personnel about hazards or any changes to airport facility services and relevant procedures. It was not processing updated information, the civil aviation regulator’s website showed on Wednesday.

In an advisory, the FAA said its NOTAM (Notice to Air Missions) system had “failed”. There was no immediate estimate for when it would be back, the website showed, though NOTAMs issued before the outage was still viewable.

Over 400 flights were delayed within, into, or out of the United States as of Wednesday at 5:31 am ET, flight tracking website FlightAware showed. It was not immediately clear if the outage was a factor.

“Technicians are currently working to restore the system,” the website showed. The FAA was not immediately available for further comment.

A NOTAM is a notice containing information essential to personnel concerned with flight operations, but not known far enough in advance to be publicized by other means.

Information can go up to 200 pages for long-haul international flights and may include items such as runway closures, general bird hazard warnings, or low-altitude construction obstacles.
