What types of electromagnetic interference can affect the flight of the DJI Mavic 4 Pro and how to avoid them: Electromagnetic interference (EMI) is one of the most critical external factors that can alter the DJI Mavic 4 Pro's behavior during flight. This interference directly affects the navigation sensors, the compass, and the connection between the drone and the remote controller. Common sources of EMI include telecommunications antennas, power pylons, large metal structures, radars, weather stations, buildings with many electrical installations, and areas with powerful industrial equipment.

The main risk of this interference is the disruption of the compass and global positioning system (GPS) signals, which can cause the drone to enter ATTI mode, lose its orientation, or hover erratically. In extreme cases, it can even lose connection with the remote controller, disabling essential functions such as RTH (Return to Home) or causing a complete disconnection mid-flight. These scenarios can endanger both the drone and the people or objects in its surroundings.

To minimize these risks, it is vital to avoid taking off or flying near identified sources of interference. Before flying, it is recommended to walk around the area with the drone powered on and observe whether any calibration or interference warnings appear in the DJI Fly app. If so, it is safest to move to a different location until the signals are stable. It is also a good idea to keep the drone away from active personal electronic devices, such as smartphones or laptops, during calibration.

Incorporating this knowledge into each flight planning allows the pilot to anticipate potential navigation failures and maintain full control of the aircraft. Listening for system alerts and flying in environments with minimal electromagnetic contamination will ensure stable trajectories, precise navigation, and a safer experience for the user and their DJI Mavic 4 Pro equipment.
