The timely knowledge of this information is essential to personnel and systems concerned with flight operations. A Temporary Flight Restriction (TFR), a type of Notices to Airmen (NOTAM) is an area restricted to air travel due to a hazardous condition, a special event, or a general warning for the entire Federal Aviation Administration airspace. NOTAMs are created and transmitted by government agencies and airport operators under guidelines specified by Annex 15: Aeronautical Information Services of the Convention on International Civil Aviation (CICA). The term NOTAM came into common use, rather than the more formal Notice to Airmen, following the ratification of the CICA, which came into effect on April 4, 1947. Notices to Airmen were normally published in a regular publication by each country’s air authorities (e.g., in Flight Magazine in the UK ). A number of developments and amendments to the CICA have resulted in the more automated system available today.

A Notice to Airmen (NOTAM or NoTAM) 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 safety of the flight. NOTAMs are unclassified notices or advisories distributed by means of telecommunication that contain information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard.
