FAA has a computer glitch that has grounded flights across the United States.

Thanks to CTOnews.com netizens for the clues of why they are not stained with dust! CTOnews.com, January 11, according to a number of US media reports, the FAA issued a statement in the early morning of the 11th eastern time, saying that due to the computer system failure caused by the power outage, the FAA was unable to update the "Navigation notice" (notice issued to pilots or air missions), and the FAA ordered all domestic flights to be suspended.

NBC quoted an anonymous source as saying that all flights in the United States were grounded after the failure.

Us President Joe Biden said he had just spoken to the Secretary of Transportation and was not sure the cause of the system failure. The current situation is that the plane can land, but can not take off.

The FAA said in a statement that it had ordered airlines to suspend all domestic flights until 9 a.m. Eastern time, while trying to restore its NOTAMS system, the mission notification system.

"We are now conducting final verification checks and repopulating the system," the FAA said in an earlier statement. "the operation of the entire national airspace system has been affected. as we make progress, we will often provide up-to-date information."

As of 6:45 et, nearly 1200 flights to and from the United States have been delayed, but so far only 93 have been canceled, according to FlightAware, which tracks delays and cancellations.

CTOnews.com learned that commercial airline pilots use NOTAMS to obtain real-time information about flight hazards and restrictions. FAA stipulates that NOTAMS cannot be the only source of information, so some flights may use other data to meet safety requirements.

At present, the system has not been restored, and flight interruptions continue.
