Drone design is also a factor, as some professional UAVs can stand up to extreme conditions. Flying Conditions: Weather conditions and visibility both factor into safe drone operation.Plan flights in advance whether you use an automated program or operate a drone manually. Flight Plans: Set a flight path prior to takeoff and obtain any necessary authorization.Ensure that drone propellers rotate freely and are securely attached. Drone Inspection: Check the battery charge level of a drone and controller.A complete pre-flight checklist could include the following sections: In addition to assessing the physical condition of drones, a pre-flight check offers an ideal opportunity to verify that components are properly calibrated and secured in advance of takeoff. Inspecting UAVs prior to flight maximizes the usefulness of findings while minimizing risk.
