The intermediate segment of an approach ends at which approach fix?

The intermediate segment of an approach is defined as the portion of the flight path that occurs after the initial approach fix and before reaching the final approach fix. This area is crucial for pilots as it allows them to establish their descent towards the runway while navigating through various controlled airspaces and preparing for the landing phase.

Choosing the final approach fix as the endpoint is significant because it marks the transition to the final phase of the approach, where the aircraft aligns with the runway for landing. The final approach fix is the designated point where the aircraft should be on a stabilized approach, indicating that the pilot should be prepared to land or continue to the missed approach point if necessary.

This segment provides pilots with the necessary guidance and parameters to safely transition into the landing sequence, which is essential for maintaining safety and efficiency in aviation operations.
