US flights halted amid NOTAM system outage

Aviation Updates Philippines – The Federal Aviation Administration (FAA) in the United States has reported a system outage with its Notice to Air Missions (NOTAM) System, causing disruptions to hundreds of flights across the country.

NOTAMs are issued by the Federal Aviation Administration (FAA) in the United States and other aviation authorities around the world to provide pilots, air traffic controllers, and other aviation personnel with important information about conditions that could affect the safe operation of flights.

As a result, all flights in the U.S. were grounded following the incident and the FAA has ordered all airlines to pause domestic departures until 10:30 PM (PHT). 

American carriers have been forced to delay flights while they await resolution of the issue, with some flights being cancelled altogether.

United Airlines said in a tweet it had temporarily delayed all domestic flights and would issue an update when it learned more from the FAA about the situation. 

Southwest Airlines said it was "closely monitoring" the situation and said it "may impact the start of operations."

In a statement, the FAA said, "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."

According to a statement released by the FAA at 9:50 PM, normal air traffic operations are resuming gradually following an overnight outage of the NOTAM system.

"We continue to look into the cause of the initial problem," the FAA stated in a tweet.

In a statement released today, Philippine Airlines announced that they are proceeding with all flights to and from the United States after the issue has been resolved.

The airline also confirmed that flight control centers in Los Angeles, San Francisco, and New York are accepting international arrivals and allowing departures.
