How do the DJI Air 3S sensors intervene during the emergency landing function: When the emergency landing function is activated on the DJI Air 3S, the sensors play a crucial role in ensuring the drone descends safely and in a controlled manner, even in adverse conditions. This function is generally used in situations where the battery is critically low, there is a connection failure, or the system detects a serious problem that prevents normal flight continuation. In these scenarios, the lower sensors immediately begin scanning the terrain to identify a suitable surface where the drone can land without damage.

The Downward Vision System analyzes the texture, levelness, and stability of the terrain, using visual data and infrared measurements to detect patterns similar to those recorded during takeoff. If it detects an area that meets safety requirements, it initiates the gradual automatic descent process. If the terrain is unfavorable, the drone can maintain a hovering altitude or hover slightly until it finds a better option, within the limits allowed by the remaining battery status. This ability to rapidly assess the environment is key to reducing risks during an emergency.

During an emergency landing, the drone continues to use its front and side sensors to avoid potential obstacles that may appear during the final phase of its descent. If it encounters an area with vertical elements such as poles, branches, vehicles, or other drones, the system can momentarily halt the landing to allow the environment to clear or for the pilot to regain control, if possible. At all times, the DJI Air 3S prioritizes the preservation of equipment, combining artificial intelligence with constant interpretation of the environment through its sensors.

This level of autonomy allows the drone to react effectively even in situations where the pilot lacks direct visibility or control of the flight. The emergency landing function, supported by sensors, turns a critical event into a much more controlled and predictable process, reducing the likelihood of violent impacts or loss of equipment. Therefore, it's important to keep the sensors clean and operational, as their performance during these times can make the difference between a safe recovery or an accident that compromises the drone's integrity.
