The ground stop has been lifted and normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the FAA’s notice to air missions (NOTAM) system.

NOTAMs provide essential information to pilots about abnormal status of a component of the national airspace system, such as ground-based navigational system failures at airports, GPS outages, and facility closures. Pilots are required to check for NOTAMs pertinent for their departure airport, route, and destination as part of preflight planning.
