NOTAM

Encyclopedia : N : NO : NOT : NOTAM

NOTAM or NoTAM is the quasi-acronym for a "Notice To Airmen". NOTAMs are created and transmitted by government agencies under guidelines specified by Annex 15: Aeronautical Information Services of the International Convention on Civil Aviation. A NOTAM is filed with an aviation authority to alert aircraft pilots of any hazards en route or at a specific location. The authority through its Flight Service Stations in turn reports all relevant NOTAMs to pilots when a pilot files an intended flight plan.

NOTAMs are issued (and reported) for a number of reasons, such as:

hazards such as air-shows and parachute jumps
flights by important people such as heads of state
closed runways
inoperable radio navigational aids
military exercises with resulting airspace restrictions
inoperable lights on tall obstructions
temporary erection of obstacles near airfields (e.g. cranes)

Software is available to allow pilots to identify NOTAMs near their intended route or at the intended destination.
