Aside the instrument side of things - the latest MSFS FSX scenery is very good - before visiting an airfield for the first time I fly the approaches to all possible runways just to get familiar with orientation, RW layout, OH joins, RW turn off points etc and I can vouch for ABZ, PTH, DND, INS, FIFE, OBAN being very realistic compared to what you actually see on approach and on the ground.
