FSX – Small Airports Of Switzerland. Seven small airports/airfields in Switzerland that are missing from the default scenery: LSGB Bex, LSGT Gruyere, LSGY Yverdon-les-Bains, LSPL Langenthal, LSTR Montricher, LSTB Bellechasse and LSGR Reichenbach. LSGR is the new ICAO code for LSAZ in the default scenery of FSX. In the default scenery this little airport also has the wrong altitude which is corrected in this LSGR airport. By Tommy Engman.
