Why is controlled descent important during landing?

Controlled descent during landing is crucial because it minimizes the risk of stalling and helps maintain a stable approach. When a pilot maintains a controlled descent, they can ensure that the aircraft remains within a safe margin of airspeed and angle of descent, which is essential for the aircraft to stay aloft and avoid stalling. A stall happens when the aircraft's wings cannot generate sufficient lift due to inadequate airflow over them, often caused by excessive pitch angle or slow speed.

By managing the descent rate and angle carefully, pilots can align the aircraft with the runway at the correct altitude and speed, ensuring a smooth and safe landing. A stable approach not only helps in controlling the aircraft better but also contributes to the overall safety of the landing process.
