Washington, Jan 11 (EFE).- Domestic flights across the United States were “resuming gradually” on Wednesday after a technical issue in the safety alerts system was fixed, the Federal Aviation Administration said.
In a tweet, the FAA said that the ground stop was lifted “following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews.”
The administration then added that the causes were still under investigation.
Earlier, the FAA had issued an order to postpone all US domestic flight departures until 9 a.m. local time due to a malfunction in the Air Mission Notification system.
The Notice to Air Missions system relays live information to pilots on abnormal developments in US airspace, dangers, and changes at airports such as runway closers.
Despite the lift of the ground stop, the number of delays on departures has increased, according to the flight tracking platform Flightaware, which has reported a total of 4,948 flight delays.
US president Joe Biden was briefed about the system malfunction by Transportation secretary Pete Buttigieg, said Karine Jean-Pierre, White House press secretary, on Twitter.
Jean-Pierre then added that “there is no evidence of a cyberattack at this point”, and said that Biden has ordered a “full investigation” to discover the causes of the system outage.
In December, the country suffered another major flight disruption due to winter storm Elliot. EFE
