FSX/P3D. I really must say, the Orbx OpenLC product has really created wonders for Europe like never before and my only complaint about the product is the fact that OpenLC currently only covers Europe. But patience is a virtue and no doubt more regions will be released soon enough. In the mean time, Orbx freeware developer Thomas Zipfel is developing EDVR Rinteln which is a small airfield in Lower Saxony, Germany, with a 600x30m asphalt runway used primarily by small GA operations and Gliders. If you are looking to add this to your Euro collection of airfields, be sure to hit the source link below for more. OpenLC really beings it to life.
