Each page of the Country Airstrip Guide (CAG) is assigned to the Location it belongs to, and shows up in the terminal page just like an ERSA FAC entry does. CAG pages are shown after any ERSA and DAP pages, and before any local files that you may have loaded via DropBox.
If you cannot find a CAG entry for your chosen destination it means that there isn't one. This happens quite often. By no means every ALA in Australia has an entry in the CAG.
If you'd like an ALA owner to have an entry in the CAG, please ask them to contact FliteAce.
