Signal de Soi

Signal de Soi is a mountain flying site in the canton of Vaud, western Switzerland, at about 1,993 m, working best with wind from the southwest or northwest and offering thermal and soaring flying with hike access. It's known locally as an afternoon site — conditions here tend to come into their own later in the day rather than first thing. Several grassy takeoff options are available on the slope, giving pilots some flexibility in exactly where they launch from. When conditions allow, a local flying school often runs a shuttle up to launch, with pilots typically meeting at the landing zone beforehand to arrange the ride. Swiss airspace around this region carries restrictions and active danger areas that change, so it's worth checking current airspace status before flying rather than assuming nothing has changed since a previous visit.

A forecast for the valley is not a forecast for the launch. Before heading to Signal de Soi, read the wind and thermals for the site itself, confirm the day's rules with the local club, and remember the standing rule — when in doubt, don't launch.
