Rules and notes
Check http://www.flob.ch for further restrictions regarding minmum altitudes around 'trainstation'... Complex airspace structure (military airfield in Unterbach/ Meiringen)! Flying without (too) much problems only on weekends... More info on http://www.flyland.ch. Airspaces in Switzerland are a tough subject, get all the info you can get before flying!
