What does NOTAM stand for?

The acronym NOTAM stands for "Notice to Airmen." This term is used to inform pilots and other personnel about important information concerning the operation of aircraft, which may affect safety or the flight operation. NOTAMs include details about changes in airports, navigational aids, airspace restrictions, and other critical information that may impact flight operations.

The other options do not accurately represent what NOTAM stands for. "Notice of Airspace Management" suggests a focus on airspace management rather than a specific advisory to pilots. "National Operations and Traffic Advisory Message" implies a broader focus on traffic advisory without directly referencing pilots. "Notice to All Manufacturers" is unrelated to flight operations and does not serve the purpose of notifying pilots about important changes or information necessary for safe navigation and operation.
