What precautions should be taken before flying near areas with strong electromagnetic fields: Before flying the DJI Mavic 4 Pro near areas with strong electromagnetic fields, such as radio stations, transmission towers, power lines, or radars, it is essential to assess the potential risks of interference with the drone's GPS signal and electronic compass. These sources can cause course deviations, signal loss, or errors in critical functions such as Return to Home (RTH). A flight affected by interference can result in erratic trajectories or even a complete loss of flight control.

To avoid these problems, it is advisable to pre-plan the flight route in open areas away from such infrastructure. If it is not possible to avoid these environments, a careful check of the system status should be performed, ensuring there are no warnings in the DJI Fly app before takeoff. Additionally, it is advisable to keep the drone in visual mode, avoiding relying exclusively on automated functions that rely on GPS.

If you notice abnormal behavior during flight, such as unexpected turns or navigation errors, it's best to abort the mission and land manually in a safe area. It's also helpful to recalibrate the compass before flight if the system suggests it, as it can minimize the possibility of errors due to magnetic interference in that specific location.

In short, operating near strong electromagnetic fields requires special vigilance and the willingness to change location if the system indicates it. A cautious pilot who understands how the environment affects the drone's sensors can make safer decisions, reducing the risk of failure and protecting both the equipment and any people and property that may be nearby.
