FSX Scenery--AFX For Ruse Airport (LBRS). This set of AFX files remove the default Shtruklovo (LB24) airfield and replace it with a simple rendition of Ruse Airport (LBRS). The airport is located in north-east Bulgaria and used to have combined civilian and military operations up until the late 1990s. However, this AFX file only depicts a purely civilian operation. ADE files are included. By Bjoern Kesten.
