To ensure flight safety, certain restrictions on environmental conditions need to be followed.
Check the weather forecast (e.g. on windfinder) for wind, rain, and temperature. Gather information about the condition of the site, e.g. intensity of radiation fields and altitude above mean sea level. Make sure environmental conditions are as follows:
Wind gusts must not exceed 30 km/h (8 m/s, 16 kts). Check with the anemometer before flying and do not fly if gusts on ground exceed 6 m/s on open fields (in confined spaces you have to rely on forecasts only). As a rule of thumb, wind speeds of 6m/s on ground on open fields correspond to wind speeds of ~8m/s in 10m-20m altitude (forecast altitude) and ~10m/s in 100m altitude. WingtraOne will return home automatically if wind speeds exceed 12m/s during flight. If you fly in high winds, check our recommendations in the Advance Flight Planning article.
Do not fly in case of rain, snow, or fog
Ambient temperature must lie between -10 and 40 degree Celsius
Do not fly in areas which probably have high-intensity radiation.
Do not fly more than 3000 m altitude above mean sea level.
Caution: If flight altitude exceeds 1500 m a.m.s.l., low-battery RTH might not work reliably. Do not rely on the automatic low-battery RTH in this situation but manually trigger RTH earlier if needed. For more information, please refer to the Advance Flight Planning article.
