The Notice to Air Missions (NOTAM) system “failed” on Wednesday morning, the FAA stated in a notice posted on its website. A NOTAM is a notice that includes information that is crucial for those working in flight operations.
What is NOTAM?
A NOTAM is a notice that contains information that is crucial to those involved in flight operations but is not known far enough in advance to be made public in any other way. It describes a component of the National Airspace System (NAS) in an abnormal rather than a normal state.

Airport operators and government organizations produce and transmit NOTAMs in accordance with the requirements of Annex 15: Aeronautical Information Services of the Convention on International Civil Aviation (CICA)
