What is a key factor in a stabilized approach?

A key factor in a stabilized approach is maintaining a constant angle and rate of descent. This means that the aircraft descends at a consistent slope, which helps to ensure that it reaches the runway at the appropriate point with the necessary speed and configuration for landing. A stabilized approach typically begins at least one thousand feet above the runway, where the pilot should establish a stable descent profile that is continuous without major fluctuations in speed, altitude, or trajectory.

By maintaining a constant angle and rate of descent, pilots can effectively manage their approach, predict how the aircraft will behave as they near the runway, and make necessary adjustments for factors such as wind or aircraft weight. This practice enhances safety by reducing the likelihood of last-minute changes, which can lead to unstable approaches and increase the risk of mishaps during landing.

Maintaining variable angles or climb rates, as suggested in the other options, would introduce unpredictability in the approach trajectory, making it difficult to ensure a safe landing configuration. A stable approach, characterized by a steady descent, is critical for successful landings in aviation.
