Where is the final approach fix for a precision approach located?

In a precision approach, the final approach fix is specifically located at the glide slope intercept. This is critical because the glide slope provides vertical guidance to the pilot as they descend towards the runway during the final stages of the approach. The aeronautical procedures designed for precision approaches typically designate this point as the point where the aircraft begins to follow the glide slope down to the runway, making it essential for ensuring a safe and controlled descent.

Being at this specific fix ensures that pilots are aligned correctly with both the horizontal and vertical guidance systems, which is crucial for maintaining the correct approach angle. This alignment helps pilots in making precise descents, improving safety and landing accuracy, particularly in low visibility situations.

Other locations mentioned, such as the beginning of the approach path or the runway threshold, do not correspond to the exact maneuvering and operational requirements of precision approaches. Likewise, the missed approach point is critical for determining when to initiate a go-around, but it is not where the glide slope intercept occurs. Thus, the correct identification of the final approach fix as being at the glide slope intercept reflects an understanding of precision approaches and their operational standards.
