A NOTAM – Notice to Airmen (Also known as Notice to Air Missions according to the FAA) – is a notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.
A NOTAM can be New, a Replacement, or Cancellation of an already existing one.
FORMS OF NOTAM
Some forms of NOTAM include:
- SNOWTAM – A special series NOTAM notifying the presence or removal of hazardous conditions due to snow, ice, slush or standing water associated with snow, slush and ice on the movement area, by means of a specific format.
- ASHTAM – A special series NOTAM notifying by means of a specific format change in activity of a volcano, a volcanic eruption and/or volcanic ash cloud that is of significance to aircraft operations.
- BIRDTAM – A specialized NOTAM providing information regarding bird strike risk or warning, particularly for low level airspace.
Unlike ASHTAM or SNOWTAM, BIRDTAM is not an official ICAO term and is not in universal use. However, the term BIRDTAM is recognized in the European Aeronautical Information System Database (EAD).
