Environmental conditions

To ensure flight safety, advisories for certain 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.  In case that environmental conditions become unsafe during the flight, press Return To Home (RTH) immediately to ensure that the drone lands safely.

Wind

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 the ground exceed 6 m/s in open fields (in confined spaces you have to rely on forecasts only). As a rule of thumb, wind speeds of 6m/s at ground level in open fields correspond to wind speeds of ~8m/s at 10m-20m altitude (forecast altitude) and ~10m/s in 100m altitude. WingtraOne will return to home (RTH) automatically if wind speeds exceed 12m/s during flight. If you fly in high winds, check our recommendations in the Flying in windy conditions article.

Precipitation/Fog

Do not fly in case of rain, snow, or fog.

Always check the weather forecast. If any precipitation appears during the flight, press Return To Home (RTH) immediately to ensure that the drone lands safely. Precipitation is dangerous because water drops can clog the airspeed sensor (pitot tube), which gives incorrect readings that may cause a crash.

Temperature

Ambient temperature must lie between -10 and 40 degrees Celsius (25 and 104 Fahrenheit). WingtraPilot will only allow you to fly if the batteries temperature is between 10 to 40 degrees Celsius. In very hot or cold temperatures, we recommend keeping the drone and pilot box in the shadow or car before and between flights.

High-intensity radiation areas

Do not fly in areas that have high-intensity radiation. In case that the high radiation is present, the telemetry connection will be lost. If you are aware that the telemetry will be lost and you are sure the flight is safe, you can manually adjust the timeout before Return To Home (RTH)  is automatically triggered. More about adjusting the connection loss timeout can be found in this Knowledge Base article: Safety parameters.

High altitude

Do not fly at an altitude of more than 3000m above mean sea level. The battery consumption at high altitude is higher and therefore safe landings can not be guaranteed. In this article, you can find guidelines about how altitude above mean sea level affects the triggering of RTH.

Flying in high latitudes or poor magnetic environments

Flying in areas near Earth poles can be a challenging environment for the magnetic compass measurement. You can find detailed information about flying in those conditions in this article: Flying in high latitudes or poor magnetic environments.
