How to Properly Use the Return to Home (RTH) System in Emergency Situations: The DJI Mavic 4 Pro's Return to Home (RTH) system is an automated feature that returns the drone to the home point recorded at the start of the flight. This tool is crucial in emergency situations such as loss of signal, low battery, or unexpected weather conditions. To use it correctly, the pilot must ensure that the home point has been properly recorded with sufficient GNSS signal. This step is easily verified in the DJI Fly app, where a confirmation message appears after the home position is established.

During the flight, the pilot can manually activate RTH at any time by pressing the corresponding button on the remote controller or from the app. The drone will ascend to a preset safety height before initiating the return. This height must be set strategically, taking into account obstacles along the return path, such as trees, buildings, or towers. If the pilot fails to adjust this setting, the drone could crash during ascent or descent.

RTH is also automatically activated if the system detects a critical battery or loss of connection. In these cases, the drone will return without pilot intervention, although it is always possible to cancel or modify the trajectory if the signal is reestablished. However, it is important to ensure the drone has clear space to land, as the RTH system does not always detect small objects in the landing area. Therefore, it is recommended to always take off from a clear area and avoid movements directly over people or vehicles.

Using RTH correctly dramatically increases flight safety and reduces the risk of getting lost or crashing. It is also a valuable tool for new pilots who may feel disoriented in complex environments. Mastering its operation, configuring it in advance, and understanding how it interacts with the environment makes RTH a true lifesaver for the DJI Mavic 4 Pro.
