I noted that "Aerodrome Chart" availability is different for Country.
In France, for instance, when you open the detailled aerodrome chart, you have all chart including parking docking, apron map or taxi details, but for the Italian aerodrome only a general map of the aerodrome is available, all the other maps, are missed.
Those maps are on our national AIP for each aerodrome, could you include also these maps ?






  

Can you be specific with reference to some exact documents please? We do not generally include parking/docking charts in SkyDemon I believe, although they would obviously be included if they were all part of the same PDF document along with other charts that we do include.

You probably partially right regarding the same PDF, but try to open on the Italian AIP:  AD2 (aerodrome database) and look at any airport, you will find the Textual and the file n. 2.1  (that is a single document PDF,  that include one or more pages depending the size of the airport, like:  aerodrome chart, docking/parking, plus sometime other maps.....)
If I look at Italian aerodrome on SD, I found the Textual, sometime other maps (depending the type of the airport) but in the Aerodrome Chart, only the first page of the original AIP document not the following docking/parking pages.
Look at LIRU, excellent job ! plenty of maps: approaching, helicopter, in/outbound route, but look at LIRZ or others, the Docking, which is part of the Airport Chart PDF is always missed. 
If I look at any French airport on SD,  I get: the Textual info and Aerodrome Chart  but that include: the aerodrome map and docking plus eventually some more  maps.
I check on French AIP, the file are the same of the Italian AIP,  for each airport you find: the Textual info and another PDF file that is a multiple page with aerodrome chart, docking/parking and so on.  

Hope now my email is understandable ,
