The alignment of imagery within P3D/FSX wasn't ever correct and very noticable at airports.
The opposite is actually the case. It is the placement of default airports which is totally inaccurate in FSX/P3D. Photo ground carpet placement is very accurate.
For that reason, when you make a photo scenery for FSX/P3D you have to edit all default airports and any landclass-related object placement.
Fortunately enough it's a quite easy (still time consuming) task thanks to convenient tools like ADE.
The concept with AFS2 is totally different, there's no crappy landclass, and no default airport.
Thus, first thing you create a scenery with Geoconvert tool, then you place airstrips...
