Takeoff description
Big, nicely sloped field with windsock. Advanced pilots usually walk up into the steeper part of the slope to get an earlier take-off time. Thermal is usually over the trees slightly to the left of the launch. Brunnihütte take off : 46.8426 N; 8.41008 E, 1860m. Schonegg: take off : 46.8435 N; 8.41665 E, 2080m.
Rules and notes
At the valley entrance (about 5 km north of the launch) there is the CTR of Buochs and Alpnach. You need clearance to enter or cross this airspace.
Pilot comments
ATTENTION: in the whole valley ('Engelbergertal') there are NUMEROUS, UNMARKED, BARELY VISIBLE cables!!! Check info at gondola stations/ ask local pilots! This cables very often are in positions, where you would expect them last!
