Departures of domestic flights are resuming across the country after the Federal Aviation Administration (FAA) restored a system that warns pilots of hazards during their upcoming flights.

The FAA first issued an advisory just past 4 a.m. on Wednesday that a technical issue impacted its Notice to Air Missions system (NOTAM), and it announced a couple hours later that it had ordered all airlines to pause domestic departures until 9 a.m. to ensure flight safety.

Thousands of flights were delayed and hundreds have been canceled, but airlines are gradually restoring normal operations.

Here’s five things to know about the system outage at the FAA:

The FAA is assessing the cause of the initial problem

The FAA said that it continues to look into the cause of the initial problem. President Biden on Wednesday reiterated that “they don’t know what the cause is.”

At 6:30 a.m. on Wednesday morning, the FAA said it was reloading the NOTAM system, which warns pilots of potential hazards such as closed runways and birds. The outage affected operations across the National Airspace System. 

The FAA grounded all planes while it was working to restore the system and repopulate it. Over a few hours on Wednesday, airlines were ordered to pause all domestic departures so the agency could “validate the integrity of flight and safety information.”

The administration has not seen evidence of a cyberattack

The White House said while flights were still grounded that it had not seen evidence of a cyberattack being the cause of the system outage. Biden spoke to Transportation Secretary Pete Buttigieg, telling him to report directly back when they learned the cause.

Biden said just before 8 a.m. that the FAA will have a “good sense” of what caused the issue within a couple hours.

“There is no direct indication of any kind of external or nefarious activity, but we are not yet prepared to rule that out,” Buttigieg told MSNBC on Wednesday.

White House press secretary Karine Jean-Pierre also tweeted that “there is no evidence of a cyberattack at this point, but the President directed DOT to conduct a full investigation into the causes.”

Buttigieg said he directed the FAA to conduct an “after-action process” to determine the causes of the glitch and make recommendations for next steps to be taken. 

Flights are back up and running

The ground stop was lifted just before 9 a.m. on Wednesday and all domestic flights gradually resumed operating. 

Departures resumed at two particularly busy airports, Newark Liberty and Atlanta Hartsfield-Jackson, about 30 minutes earlier to clear up air traffic congestion in those areas.

But the ground stop seems to have had an impact on domestic flights for at least the rest of the morning, if not longer. Over 7,000 flights within, into or out of the United States were delayed Wednesday, and more than 1,000 were canceled, according to the flight-tracking website FlightAware.

Reuters reported that more than 21,000 flights were scheduled to depart U.S. airports on Wednesday.

Travelers are likely to face delays throughout the day or longer

With hundreds of flights across the U.S. delayed as a result of the system outage, it will likely take a day or more for flight operations to resume as usual.

The flight disruptions on Wednesday follows massive Southwest Airlines cancellations two weeks prior, when the airline canceled more than half of its flights over a three-day period after Christmas and thousands of passengers were left stranded.

The issue occurred after the airline’s scheduling system struggled to route pilots and flight attendants to the right planes following strong winter storms that hit Denver and Chicago. Southwest CEO Bob Jordan said its scheduling system needs to be modernized.

The outage prevented flights from taking off, not landing

There was no real danger to flying during the system outage because flights were grounded. 

Planes that were already in the air were safe to land, but those still on the ground could not take off safely.

The FAA tweeted that pilots review the NOTAM system before they take off, so they would be aware of any possible hazards in advance of departure.

Multiple airports internationally also said that they were able to continue flights into the U.S. without any interruption. NBC reported that spokespeople for Air France, Frankfurt Airport in Germany and Gatwick Airport in London said they were still operating to and from the U.S.
