Takeoff description
Take-off 'Le Méruz'
Pilot comments
Only 2 or 3 wings can simultaneously take off but the field is wide enough for every one to prepare their wings. Due to the valley breeze, the wind at takeoff is almost allways coming front. Tall trees at end of take off, not exactly beginners friendly...
