The Flight Safety and Human Factors Programme has produced the manuals and circulars listed below. In general terms, ICAO manuals are large, permanent documents which address long standing issues. They are updated periodically. In contrast, circulars are typically shorter documents that address one specific topic that is of immediate, but not necessarily long term concern. Circulars may also address evolving issues, the solution of which are not yet mature enough to be included in manuals. Circulars will no longer be printed when the topic is no longer of interest. Alternatively, the material addressed in a circular may be incorporated into a manual. Manuals and circulars are available for purchase.
