What are NOTAMS?

Decoder:  Braking Action | Weather Contractions | Abbreviations list | NOTAMs Contractions | Aircraft

NOTAM, "NOtice To AirMen", are notices containing essential flight operation information not known sufficiently in advance to publicize by other means. Just like weather reports, they include endless abbrieviated text (known as a contraction) which are sometimes difficult to figure out.  Translate NOTAMs here!

Want the complete reference guide?  Click the green thumbnail to the above right. 

Types of NOTAM's include the following: 

  1. NOTAM(D): Information that requires wide dissemination and pertains to enroute navigational aids, civil public use landing areas listed in the Airports Facility Directory and aeronautical data related to IFR operations. 
  2. NOTAM(L): Information that requires local dissemination, but does not qualify as NOTAM(D) information. This includes, but is not limited to, aircraft jettisoning fuel, bird activity, moored balloons, military training activity, etc. This type of NOTAM no longer exists, now part of "D" NOTAMs and distributed nationwide.
  3. FDC: Information that is regulatory in nature pertaining to flight including, but not limited to, changes to charts, procedures, and airspace usage. It includes TFRs.

Types of "D" NOTAMs

Runways 3 and 21 are closed to aircraft.
Taxiway F lights are out of service.
The ramp in front of the east side of the terminal has ongoing construction.
The apron near the southwest taxiway C in front of the hangars is closed.
Aerodromes: The airport beacon is out of service.
OBST TOWER 283 (246 AGL) 2.2 S LGTS OTS (ASR 1065881) TIL 0707272300
Obstruction: The lights are out of service on a tower that is 283 feet above mean sea level (MSL) or 246 feet above ground level (AGL) 2.2 statute miles south of the field. The FCC antenna structure registration (ASR) number is 1065881. The lights will be returned to service 2300 UTC (Coordinated Universal Time) on July 27, 2007.
Navigation: The VOR located on this airport is out of service.
Communications: The Automatic Terminal Information
Service (ATIS) is out of service.
SVC TWR 1215-0330 MON-FRI/1430-2300 SAT/1600-0100 SUN TIL 0707300100
Service: The control tower has new operating hours, 1215-0330 UTC Monday Thru Friday, 1430-2300 UTC on Saturday, and 1600-0100 UTC on Sunday until 0100 UTC on July 30, 2007.
Service: All fuel for this airport is unavailable until July 29, 2007 at 1600 UTC.
Service: United States Customs service for this airport will not be available until August 15, 2007 at 0800 UTC.
Airspace. There is an airshow being held at this airport with aircraft flying 5000 feet and below within a 5 nautical mile radius. Avoidance is advised from 2000 UTC on July 15, 2007 until 2200 UTC on July 15, 2007.
