PANC Anchorage Alaska Airport Flattens. for use at PANC Anchorage, Alaska Airport for flightsim 2004 only. While flying into PANC recently, I noticed the water was encroaching on the land near Runways 14 and 6 in a most unrealistic manner. This package provides two flattens which will eliminate that problem. Tested with the default scenery and with the Frame Rate Friendly Studio version of PANC. It has not been tested with any terrain enhancement such as Ultimate Terrain. Please unzip to a temporary folder and follow the very simple installation instructions.
