X-Plane 10 Scenery--EPKM Katowice-Muchowiec Airport, Poland. Katowice-Muchowiec Airport is a general aviation airport in the Muchowiec neighborhood of Katowice, Poland. Due to damage by coal mining, the airport is only used for local sport flying. A newer concrete runway is proposed but has not been built. This airport is sometimes used by the locals who do not want to drive the 30 km distance to the Katowice International airport. Requires OpenSceneryX (OPENSCENERYX.ZIP) By Fred Schutzman.
