How does terrain altitude affect the flight safety of the DJI Mavic 4 Pro: Terrain altitude directly affects the safety and stability of the DJI Mavic 4 Pro due to factors such as atmospheric pressure, air density, and the limitations of barometric sensors. At higher altitudes above sea level, the air is thinner, reducing the efficiency of the propellers and propulsion system. This can result in a decrease in available power, shortening flight range and making the drone more vulnerable to conditions such as sudden gusts of wind.

The Mavic 4 Pro's positioning system uses GPS, GLONASS, and Galileo to determine its altitude and position, but also relies on the barometric altimeter to stabilize its flight. When the drone operates in mountainous regions or at high altitudes, the margin of error of these systems may increase, and if the terrain has steep slopes, the risk of collision increases if the minimum flight heights and exclusion zones are not correctly configured.

Additionally, altitude calibration during takeoff is essential. If the drone takes off from an elevated surface without properly detecting the reference point, automatic return or relative altitude calculations may be incorrect, jeopardizing a safe landing. Therefore, before flying in high mountainous or hilly areas, it is advisable to calibrate the compass and sensors at the takeoff site to avoid reading errors.

To mitigate these risks, pilots should familiarize themselves with the area's topographical features and activate features such as the topographic map in the DJI Fly app. Setting manual altitude limits, avoiding flying in extreme weather conditions, and maintaining constant vigilance are best practices for operating safely in high-altitude environments.
