I wish I could take nice shots with my DJI Air 3 on top of a cloud layer at sunset or sunrise. Can I break through the cloud layer safely with my drone ?
Technical analysis
Hello Timothy,
Who hasn’t dreamed one day of taking a stunning drone shot with the sun skimming across the clouds ?
Which are the risks involved in breaking through the cloud layer ?
▪︎ Regulatory aspect : Flying BVLOS (Beyond Visual Line of Sight) is not regulatory compliant. Such operations are highly restricted and only permitted with special authorizations from the aviation authority.
Hazards :
▪︎ Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. Further if these water droplets become large enough, they will fall as precipitation in the form of rain, hail or snow.
▪︎ Inside the drone’s body are sensitive electronic components, while the motors contain copper coils and magnets – neither of which reacts well to the moisture present in clouds.
▪︎ When a drone flies into the clouds where temperatures range from + 10 ° C (50 ° F) to – 20 ° C (-4° F), water droplets can freeze into ice. This ice may stick to the body and the propellers. The effects of icing include increased weight (icing of the body) and reduced lift (icing of the propellers). In the worst-case scenario, the drone may loose its stability and crash. Sometimes, larger water droplets in the atmosphere at temperatures well below 0°C/32°F can lead to severe icing conditions. Ice can accrete rapidly, forming a layer of clear ice over the drone and leaving no chance of recovery.
▪︎ The strong upward and downward air currents inside cumuliform clouds can make the drone much harder to control. Stratiform clouds (Fog) are more stable.
👉 From above, the downward vision system might mistake the cloud layer for an obstacle.
As per User Manual page 57 : Vision Positioning and Obstacle Sensing can be temporarily disabled in clouds and fog or when an obstacle is detected for landing.
