Notices to Air Missions

A NOTAM, or Notice to Airmen, is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are created and transmitted by government agencies and airport operators under guidelines specified by Annex 15 of the Convention on International Civil Aviation, and are disseminated to pilots through various means. The NOTAM system has undergone several developments and amendments over the years, including the introduction of web-aware systems, but has been criticized for its unintelligibility and lack of effectiveness in alerting pilots to potential hazards.learn more on wikipedia
