Notice to Airmen (NOTAMs) A NOTAM is a communication that provides crucial information for individuals involved in flight operations, which is not available early enough to be disseminated through alternative channels. It indicates the irregular condition of a part of the National Airspace System (NAS) – rather than its standard condition.
In numerous nations, NOTAMs are disseminated by: Civil aviation authorities (for instance, DGCA in India), air navigation service providers, and airport operators. They are globally distributed via the International Civil Aviation Organization (ICAO) system.
