A new study ‘Weather constraints on global drone flyability’ examined how weather conditions – for example rain and temperature- influence the flyability of drones.
The researchers found that most drones have an operational temperature range of 0 to 40 °C, maximum wind speed resistance of 10 m/s and are not suitable to fly in the rain. Comparing the weather resistance specifications of drones with the 10-year weather analysis of the ERA5 reanalysis dataset revealed that bad weather conditions considerably reduce the operational time of drones.
Hence, the researchers suggest that improving the rain resistance, the wind resistance and the operational temperature of drones could increase flyability from 40% to 87% on average. Moreover, the authors emphasised the importance of weather-related standards for drones. Besides, accurate weather forecast could aid drone operators to optimise their drone operations.
