The problem of presenting up-to-date base information to users of Aeronautical Charts has plagued chart producers for many years and is becoming more complex as modern technology enables man to literally change the appearance of the earth's surface overnight. The prime objectives of the Maintenance of Knowledge Programme are to improve the compatibility and reliability of the Aeronautical Chart Bases, and to keep them as current as possible within the demands of production and user requirements. Two tools, the Cartographic Information Folio, and the Remedial Action File, have been adopted for operating the Maintenance of Knowledge Programme. The purpose of this paper then, is to explain these tools and how they are used in the Maintenance Programme.
