Why is it recommended to avoid flying the DJI Mavic 4 Pro near power lines or communication towers: Flying near power lines, communication towers, or facilities with powerful electromagnetic equipment poses a significant risk to the operation of the DJI Mavic 4 Pro. These environments generate intense electromagnetic fields that can interfere with the drone's electronic compass and navigation system. The compass is one of the key sensors for the drone's orientation and positioning; if it experiences interference, the flight may become unstable, and the Return to Home (RTH) function may activate incorrectly or fail.

In addition, this interference can affect the accuracy of the drone's Global Positioning System (GNSS). The DJI Mavic 4 Pro relies on satellite signals to maintain its position and trajectory; if these signals are distorted by high-frequency radio waves, the drone may experience location errors, drift, or even enter Atti mode, losing automatic stabilization. This requires the pilot to have advanced skills to maintain manual control of the flight.

Another critical aspect is the risk of video transmission or control signal failures. Communication towers can emit frequencies that directly interfere with the drone's OcuSync system, reducing range or causing sudden transmission interruptions. In dense urban environments, where the number of wireless signals is high, the probability of interference increases, increasing the risk of accidents or losing the drone.

For all of the above reasons, it is recommended to maintain a minimum distance of several hundred meters from these sources of interference. Before flying, the pilot should analyze the environment using the electromagnetic interference map in the DJI Fly app or follow the warnings issued by the system. Careful planning of the environment is key to ensuring safe, stable flights within reliable navigation parameters.
