X-Plane 10 – Airports Of Schleswig Holstein, Germany 1.1. This file contains all airports of the German state Schleswig-Holstein. The airports are built entirely with the default Laminar Research scenery library. All airports with ICAO identifiers are included, and then some more (usually small glider fields) with fictitious identifiers. Just unzip all folders into your /custom scenery folder. By Jan Vogel.
