Final Approach Fix (FAF) defines which of the following?

• A. The beginning of the final approach segment and the point where final segment descent may begin
• B. The runway threshold
• C. The initial approach fix
• D. The missed approach point

Answer: (A)

The Final Approach Fix marks where you begin the final approach segment. It defines the start of the final descent toward the runway, meaning from this fix you’re committed to the landing phase and descend along the published final approach path to the missed-approach point or runway. This is why the correct choice describes both the beginning of the final approach segment and the point where final-segment descent may begin.

The runway threshold isn’t a designated fix that starts the final approach, it’s simply the end point of the approach path. The initial approach fix is a different point that marks the start of the initial/ intermediate segments, not the final. The missed approach point is where you must execute a missed approach if landing isn’t achieved, which occurs at the end of the final approach segment, not at its start.
