(CNN) — A Federal Aviation Administration (FAA) system that provides pilots with information they must read before flying is experiencing disruption affecting flights in the United States.
It is unclear how many flights will be affected, as some airlines may operate without information from the system, known as the NOTAMS system, or Notice for Air Mission.
The FAA says that “some features are starting to come back online,” but added that it will take time to figure it out. An earlier notice read: “Technicians are currently working to restore the system and there is no estimate for service restoration at this time.”
“We are conducting final validation checks and are now reopening the system,” said an FAA statement. “Operations throughout the national airspace system are affected. We will provide frequent updates as we move forward.”
Transportation Secretary Pete Buttigieg tweeted this morning: “I contacted the FAA this morning regarding an outage affecting a critical system for providing safety information to pilots. The FAA is working to resolve this issue quickly and safely so that air traffic can continue.” resume normal operations and continue to provide updates.”
The union representing US airlines, Airlines for America, says the outage is “causing significant operational delays.”
United Airlines said it has temporarily delayed all domestic flights.
American Airlines said in a statement that it is “closely monitoring the situation, which affects all airlines, and is working with the FAA to minimize disruption to our operations and for customers.”
The airline says the NOTAMS system that experienced the outage provides “vital flight safety operations information”.
FlightAware, which tracks delays and cancellations, showed that nearly 1,200 flights to and within the United States were delayed as of 6:45 a.m. ET, but only 93 were canceled so far.
NOTAMS is used by commercial airline pilots to obtain real-time information on in-flight hazards and restrictions. The FAA determines that NOTAMS should not be relied upon as the sole source of information, so some flights may use other data to meet safety requirements.

Flights to the United States continue to take off from Amsterdam and Paris despite an FAA system outage that caused a widespread outage in the US.
A spokesperson for Schiphol Airport told CNN that “an alternative solution had been issued” and that therefore flights were still leaving Amsterdam.
No flights have been canceled from Paris’s Charles de Gaulle airport, but delays are expected, according to the airport’s press office. Frankfurt Airport also told CNN it was not affected.
A spokesperson for Heathrow Airport told CNN they were “not aware of canceled flights and flights to the US had recently departed” but would send an updated statement shortly.
