in Switzerland we have some airfields which are private and do not have an official approach chart in the skyguide AIP. But they are available on their website for download. 

thanks to qgis, you can create self made referenced charts. Is this supported with Skydemon? Which settings must be used for the best experience? I was able to save the PDF under the airport but not as georeferenced so far and with no option to overlay it to the base map.

best regards
