Notice to Air Missions
A NOTAM is a notice containing information essential to personnel concerned with flight operations but not known far enough in advance to be publicized by other means. It states the abnormal status of a component of the National Airspace System (NAS) – not the normal status.
The acronym updated December, 2nd, 2021 to be more inclusive of all aviators and missions.
