Rules and notes
Max Alt: - 3950m during MIL 'on' - 4500m during MIL 'off'. Flying East: be aware of regulations concerning 'Muenster'-AD (sailplanes)! XC towards West: TMA 3 of 'Sion'-AD can become a factor. Airspaces in Switzerland are a tough subject, get all the info you can get before flying: www.flyland.ch. DABS (active danger areas etc): https://www.skybriefing.com/
