AIC

Aeronautical Information Circulars (AIC) are notices containing information that does not qualify for the origination of a NOTAM or for inclusion in the AIP. As a general rule, AICs refer to subjects that are of an administrative rather than an operational nature. They are, however, also used to publish advanced warnings of impending operational changes and to add explanation or emphasis on matters of safety or operational significance. Aeronautical chart issues and corrections are also notified through the medium of the AIC.

In order to facilitate easy selection of AICs they are printed on different coloured paper according to their subject matter as described below:
