WASHINGTON: Normal air traffic resumed after operations were stalled due to a major outage in the computer system of the US regulator Federal Aviation Administration on Wednesday. In the meanwhile, FAA has activated a hotline.

The White House has briefed US President Joe Biden on the flight’s situation in the country after a technical glitch in the system of the Federal Aviation Administration forced the authorities to ground nearly all flights.

The White House has also ruled out a cyberattack on the FAA, as informed by press secretary Karine Jean-Pierre.

According to media reports, at least 3700 flights were grounded and 550 flights were canceled. Overall 21,000 flights were scheduled to take off from the USA today. All domestic flight departures were paused until 9 am Eastern Time.

FAA has tweeted, “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. We will provide frequent updates as we make progress.”

The Federal Aviation Administration stated that it is ‘experiencing an outage that is impeding the update of Notice to Air Missions (NOTAMs)’ and that ‘all flights are unable to be released at this time’ due to the enormous glitch that caused flight delays.

FAA is a system that alerts pilots and other flight personnel about hazards or any changes to airport facility services and relevant procedures.
