Local flying reaches 57% because launch wind and basic weather stay usable, but the day does not generate enough lift to feel easy or rewarding for long.

📊 Wind & thermals aloft
🎓 Full view
💡
Overview: colored arrows show wind speed and direction. Yellow to orange cells highlight the active thermal layer. The LAUNCH line marks the takeoff altitude.
Mean wind is the constant speed. Gusts are sudden accelerations. Thresholds: 15 km/h = caution, 25 km/h = critical.
🌡 Temperature
🎓 Why it matters?
💡
Launch temperature affects your comfort and safety. Below 0°C, your fingers go numb and handling controls becomes difficult.
💧 Precipitation
🎓 Impact on the wing
⚠️
Golden rule: never fly in rain or snow. Water weighs down the wing (up to +5 kg), alters its aerodynamic profile and reduces lift. Snow can freeze on suspension lines.
