AirspaceNotice to Air Missions (NOTAM)
Also: NOTAM, Notice to Airmen
A time-critical notice about conditions or changes, such as closed runways or restrictions, that pilots must review during flight planning because it is too new for charts.
“Notices to Airmen, or NOTAMs, are time-critical aeronautical information either temporary in nature or not sufficiently known in advance to permit publication on aeronautical charts or in other operational publications.”
