Would like to fly to various bases in Antartica, such as NZIR, NZWD and NISD (Ice Station Delta).Unfortunately the AIRAC database doesn't have. Would appreciate any guidance on how to add them to the PMDG airports database.Thanks & regards

I might be wrong but if an airport is not in the data base - real or PMDG - the only thing you can do is construct it yourself in the FMS. Go to REF INDEX > NEW WAYPOINT, in IDENT enter the runway ident eg RW27. You can then enter its LAT/LONG, ELEV, LENGTH, CRS and CATEGORY.You can also construct some waypoints for an approach like OM, FAF etc. in the REF INDEX > NEW WAYPOINT page using PLACE/BRG/DIST from your new runway.Again I'm not sure but you can only use this runway for an approach, not take-off because there's insufficient data to initialise?I'll try it as well on my next flight, will be fun to land on ice at a place like McMurdo...Chris G

Search for posts about old Kai Tak, there you can read about how to add new airports to the airac.

Before you try adding or editing info in the navdata, this might be helpful: http://ops.precisionmanuals.com/wiki/NAVDATA_Data_Dictionary
