I'm not with Laminar Research, just a fellow simmer in the UK who has just come across your Q&A post above.
When you use the phrase 'map', I'm not entirely sure what you are referring to, but I guess you mean a diagram of the X-Plane 11 folder/file structure?
If this is the case and you simply wish to know where to install new aircraft files, then it will be in one of the following:-
C:\X-Plane 11\Aircraft\Laminar Research
C:\X-Plane 11\Aircraft\Extra Aircraft
If you purchased your copy of X-Plane 11 from Steam, then the file structure will be slightly different.
Please ignore this message if you have by now, resolved the issue?
