Thank you very much for the details. I needed this. The big advantage of DD product is actually landmarks outside the airport that are important for VFR flying. DD version of Salzburg airport is fantastic for exactly this reason. Initially, I hesitated because the thumbnail of the MS version in the content manager has some bridge (see my screenshot in the topic), and just now, I realize that probably that bridge has nothing to do with EGGP as there are no mountains in the area.
