If you want to superimpose airport maps or terminal charts over the basemap you can use the custom georeference mapping option in FlightSim Planner. You’ll need a special piece of called MapCruncher from microsoft which you can download here (windows only). Next you’ll need a locally installed webserver or (preffered) you can create a account with some free service like infinity free for instance. Find the chart you need from your local AIP or any other source. Convert this (mostly) pdf file to the png format using an opensource tool like GIMP, open it in MapChruncher and start creating georeferenced layers. The resulting rendered files must be uploaded to the webserver preferably in the “maps” directory. Put the correct URL in the setup page and start downloading your maps..
We are preparing a detailed tutorial on how this is done..
