What denotes the Final Approach Fix (FAF) on a Precision Approach?

The Final Approach Fix (FAF) on a precision approach is denoted by the glideslope intercept. This is the point where the aircraft intercepts the glide path, which is the designated slope or angle for the descent to the runway. In precision approaches, the glideslope provides vertical guidance that complements the lateral guidance offered by the localizer, allowing pilots to maintain the correct descent profile.

Understanding the FAF's role is crucial for pilots, as it marks the beginning of the final approach segment. Upon reaching this fix, pilots typically initiate a controlled descent along the glide slope to safely land at the airport. It is essential for maintaining the appropriate altitude and spacing during the approach phase.
