Altitude hold

Altitude hold is a feature in drones and aircraft that automatically maintains a consistent height above the ground. Using sensors like barometers or GPS, the system detects any change in altitude caused by wind or movement, then adjusts the throttle or engine power to keep the drone steady at the desired height. This allows for stable and smooth flight, making it easier to capture photos or perform tasks without constantly manual adjustments. Essentially, altitude hold acts like an automatic “rise and fall” control, ensuring the vehicle stays at a specific elevation without user intervention.
