What I have found is Airfield condition relates closely with SkyVector.
It would not surprise me if SkyVector’s details are layered onto the terrain.
Also, on the Airfield’s info page, there is a list of fields with Instrument Procedures.
Where I am, central UK, this list corresponds with MSFS fields with ATC.
All smaller fields with AFIS are silent in MSFS. Not even a weather report.
