Describe the characteristics of a stable approach for landing.

A stable approach for landing is characterized by a consistent airspeed and descent angle. This stability ensures that the aircraft is properly configured and that the pilot has precise control throughout the final approach to the runway. Consistent airspeed is crucial because it allows pilots to maintain lift and control as they descend, minimizing the risk of stalling. A steady descent angle complements this by enabling the pilot to maintain a predictable path toward the runway threshold, which is essential for a successful landing.

In contrast, fluctuating airspeed and descent rate, or rapidly descending with varying angles, can lead to loss of control and make it difficult to achieve a safe landing. These conditions may result in a lack of predictability, complicating the pilot's ability to manage the landing phase effectively. A gradual approach without defined speeds lacks the precision necessary for accurate landings, which can also increase the risk of a mishap during touchdown.
