How do sudden altitude changes affect the DJI Air 3S's sensing ability: Sudden altitude changes can significantly affect the DJI Air 3S's sensing ability, especially when performed in environments with nearby vertical obstacles. During rapid ascents or descents, the sensors must recalibrate their perception of the environment in real time to adapt maneuvers and avoid collisions. This process is more complex when the drone is in tight spaces or near roofs, trees, or other structures, as the sensors' viewing angle can suddenly change, creating temporary blind spots during the altitude transition.

During an accelerated ascent, the lower sensors momentarily lose ground reference, while the upper sensors must immediately activate to avoid impacts with obstacles above the drone. If the environment includes low roofs, branches, or overhanging structures, the APAS system must quickly interpret the data and execute evasive maneuvers. These types of sudden changes can also cause the system to suspend intelligent features such as FocusTrack or POI, as the temporary loss of visual reference can compromise the accuracy of automatic tracking.

During rapid descents, the drone relies heavily on lower sensors to determine the distance to the ground and avoid forced landings or premature contact. If the descent occurs over reflective, unstable, or low-contrast surfaces, the system may misinterpret the altitude, resulting in a rougher-than-expected landing or, in the worst case, a descent to an unsafe surface. Therefore, controlled and gradual descents are essential to allow the sensors to work accurately.

To ensure optimal performance during altitude changes, it is recommended to perform smooth vertical movements with good visibility of the surroundings. The operator should avoid flying directly up or down in areas with ceilings or uneven surfaces without first checking the available space. It is also advisable to keep all sensors clean and in good condition, since the detection system's ability to adapt to altitude variations depends entirely on the quality of the data it can interpret at each moment of the flight.
