Hundreds of airplanes were suspended across the United States on Wednesday, January 11, 2023, due to a technical problem in the Federal Aviation Administration’s system (FAA). The magnitude of the delays was unknown at the time.
“The FAA is 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,” FAA said.
The failure of the Notice to Air Missions system, which warns pilots and other workers of airborne difficulties and other delays at airports around the country, is to blame for the outage.
“The FAA is still working to fully restore the Notice to Air Missions system following an outage. While some functions are beginning to come back online, National Airspace System operations remain limited,” the FAA said in another update on the evolving situation.
While the FAA has not mandated that aircraft be grounded due to technical failure, most carriers have elected to ground their planes. According to FlightAware, a flight tracking website, over 700 flights within the United States were delayed and over 90 were canceled on Wednesday morning.
