Dont worry, the current Swiss chart is all in Ft.
The weather is supposed to be wonderful here this weekend with temps upto 30C. So if you are planning to stop off at some mountain airports just be careful. I was in LSZS abt 3months ago. The airport elevation is approx 5600ft but at 2pm the density alt was over 7200ft. It can catch a few people out.
As previously mentioned, all of the local airports have a "home" briefing computerized system which makes life very easy for upto date weather / planning etc etc
Just treat those big lumps of rock sticking out of the earth with great respect, they have a very nasty bite. Even on a sunny day the winds in the valleys can make life interesting. But dont let that put you off. A lot of the flying is done in the valleys below the peaks which makes for breath taking views.
Have fun.
