The ICAO annex you need is Annex 14 'Licencing of Aerodromes'. The UK CAP 168 is broadly similar and available on-line, unlike ICAO documents. Why oh why don't ICAO make their documents officially available on-line? Surely the relatively small amount of revenue generated by selling paper docs isn't balanced by the reduction in safety because not enough people get to see the docs. Even the UK CAA make all their publications available on-line for no cost to the down-loader.
There ARE sites around the world that make some ICAO docs available, but these are 'unofficial' and don't guarantee the current edition.
