What does the Smart Landing (SL) function monitor during an approach?

The Smart Landing (SL) function is designed to enhance approach safety and performance by monitoring several critical parameters. During an approach, it focuses on a stabilized landing, ensuring that the aircraft is on the right path for a successful touchdown.

A stabilized approach indicates that the aircraft is flying at the correct speed, angle, and configuration as it nears the runway, which is foundational for safe landing procedures. Additionally, it considers the potential for long landing, which would involve monitoring the aircraft’s position relative to the runway threshold and assessing whether the landing distance is appropriate. Altimeter readings are also crucial, as they help ensure that the aircraft is at the correct altitude to land safely.

In essence, this combination of stabilization checks related to approach conditions greatly contributes to the safety and efficiency of the landing process, which is why this choice is the correct one. The other options either focus on too few parameters or do not encompass the comprehensive approach criteria that Smart Landing functions monitor.
