Takeoff description
Depending on wind direction in the top. The easiest is to take off with east or north wind from the ski slopes itself. South take off where there are a couple of wind stripes is quite steep and technical, there's almost no place to run. So it's a matter of putting the wing in the air and fly, which for some pilots and depending on the conditions can be a problem.
