How important is it to perform a complete visual inspection of the drone before flight: Performing a pre-flight visual inspection of the DJI Mavic 4 Pro is a critical practice that can make the difference between a successful flight and a technical incident. This step, often overlooked by novice pilots, allows physical damage, loose parts, or worn components to be detected before they cause problems during flight. Items such as cracked propellers, improperly folded arms, misaligned cameras, or loose connections can put the drone, people, or property on the ground at risk.

An effective inspection begins with the most exposed elements: the propellers and motors. The propellers must be clean, free of bends and dents. Any defect, no matter how small, can generate vibrations that interfere with flight sensors or affect video quality. Similarly, the motors must rotate freely without making unusual noises and must not have any obstructions or accumulated dust. Cleaning these components helps maintain their aerodynamic efficiency.

The battery should also be checked to ensure it is firmly inserted and that its LEDs show adequate charge levels. An improperly inserted battery can disconnect mid-flight, causing an uncontrolled fall. Likewise, checking the status of the camera and gimbal is essential, ensuring they move smoothly and are not obstructed. The gimbal guard should always be removed before turning on the drone, as it can block self-calibration.

Finally, a general inspection of the fuselage is recommended to identify any cracks, moisture buildup, or dust that could affect vision sensors or other electronic components. A detailed and systematic inspection exponentially increases flight safety and prolongs the lifespan of the equipment, especially when performed routinely before each operation, regardless of whether the flight is short or long.
