NOTAM

NOTAM or NoTAM is the quasi-acronym for "Notice To Airmen". 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 4 April 1947. Notices to Airmen were normally published in a regular publication by each country's air authorities such as Flight Magazine in the UK. A number of developments and amendments to the CICA have resulted in the more automated system available today.
