💨 Wind at launch

🎓 Safety thresholds
💡
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.
