This is EPRZ. Apart from the big aerodrome, there is a small GA field, close to it. Note that the demo version will not have a phototexture, or it may be in low resolution (I do not remember). The 3d runway and aprons are not availble as well.

PS: Close to the EPRZ there is an aerodrome EPML - Mielec. This has been a test airfield of the PZL Mielec works for years. So, if you want to have a detailed test field for Eastern European birds, grab it from Avsim. The EPML is a highly detailed scenery made by a guy who worked on the Polish Airports vol 1 and 2 for Stanislaw Drzewiecki.
