How this works. Each day gets a flying-chance % for the best of the launch sites (Zugerberg, Brunni/Engelberg, Büelen/Wolfenschiessen, Niederbauen/Emmetten). Per site the 5-point check scores green=100, yellow=50, red=0 and averages; any red caps it at 50% (two reds at 30%), fog trims it, and two hard NO-GOs force 0%: clear föhn (Δp≥4 hPa and strong southerly in the föhn valleys) or clear rain 08-15h at that site. ≥75% GO, 50-74% CAUTION, <50% NO-FLY. Föhn & nationwide wind use Lugano/Zürich/Altdorf/Sarnen/Engelberg/Wolfenschiessen; storms compare ICON-CH1 + ICON-D2 per site (blended fallback beyond their range); fog is sampled at landing / mid / launch / launch+400 m for each site. The General forecast panel pulls the official MeteoSwiss text and highlights the SHV "Alarmzeichen" keywords; when present it can only push a category to more caution, never less. Decision support only — YOU are the pilot, YOU decide. Based on the SHV strategy.
