ABOUT ICAO PUBLICATIONS
Most ICAO publications are issued in English, French, Russian and Spanish; Arabic and Chinese versions are being introduced on a gradual basis. Individual publications indicate which language versions are available.

AMENDMENT SERVICE
Certain ICAO publications are subject to amendment. These include Annexes to the Convention, Procedures for Air Navigation Services (PANS), Technical Manuals and the various parts of the Training Manual. Holders of these publications should write to ICAO whenever they wish to receive amendments, supplements, or corrigenda; their publication is announced regularly on the "Recent Additions" page.
All bulk purchasers of ICAO publications for distribution to their staff should obtain their supply of amendments also in bulk for distribution to holders of relevant publications, since ICAO cannot provide individual amendment service directly to all such holders of amendable publications.
STANDING ORDER SERVICE
Recurrent publications can be ordered by standing order. Through this service, publications and their amendments are automatically sent as they become available, guaranteeing immediate shipment of new editions, new titles and amendments. Standing orders can be established for all ICAO publications, groups of publications on the same subject or for individual titles. It is necessary to have a deposit account in order to establish a standing order. For information on deposit accounts, click on "Accounts". Note – The standing order service is not available for audio-visual training aids.
BACK ORDERS
Due to uncertainty of reprint schedules and availability of new editions, this service is not available.
