What precautions should be taken when flying in environments with high electromagnetic interference: Operating the DJI Mavic 4 Pro in areas with high electromagnetic interference should be approached with extreme caution, as these environments can affect the compass, the GNSS positioning system, and the transmission between the drone and the remote controller. Places such as power stations, telecommunications towers, airports, or even areas with many Wi-Fi networks can generate electromagnetic fields that directly interfere with the drone's electronics.

One of the main effects of this interference is the disorientation of the compass, which can lead to incorrect heading readings and, consequently, unstable trajectories or erratic flights. It can also disrupt the operation of the RTH function, causing the drone to fail to return to the correct takeoff point or to fly in the wrong direction. These situations compromise the safety of the operation and can lead to the total loss of the drone.

To minimize risks, it is recommended to perform a GPS and compass status check in the DJI Fly app before takeoff. If an unstable magnetic environment is detected, the system will alert the pilot to recalibrate the sensors or change location. Additionally, avoiding takeoff near metal structures or sources of electromagnetic radiation is a good practice to maintain the integrity of the navigation system.

During flight, any sudden indication of compass error or loss of signal should be treated as a critical alert. The pilot should be prepared to activate a manual emergency landing or use a flight mode with less reliance on automatic positioning. In conclusion, although the DJI Mavic 4 Pro features advanced systems to resist interference, the operator's judgment remains the best resource to ensure safe flight in challenging environments.
