International NOTAM Office

The NOF: Annex 15 defines an international NOTAM office (NOF) as “an office designated by a State for the exchange of NOTAM internationally”. It further states “An aeronautical information service shall arrange, as necessary, to satisfy perational requirements, for the issuance and receipt of NOTAM distributed by telecommunication.”

NOTAM: A notice distributed by means of telecommunications containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.

Checklists and lists of valid NOTAM: Checklists of valid NOTAM must be issued periodically (at least once a month) over the AFS. In addition, the checklists must refer to the latest AIP Amendments, AIP Supplements and at least the internationally distributed AIC. Furthermore, a monthly printed plain-language list of valid NOTAM, including references to the latest AIP Amendments, AIC issued, and a checklist of AIP Supplements must be forwarded to all recipients of the Integrated Aeronautical Information Package.
