On a precision instrument approach, which point marks the commencement of the final segment?

• A. Final Approach Fix (FAF)
• B. Final Approach Point (FAP)
• C. Initial Approach Fix (IAF)
• D. Missed Approach Point (MAP)

Answer: (B)

In a precision instrument approach, you move through segments as you descend toward the runway. The point where you begin the final descent along the glidepath is the Final Approach Point. This is the moment you commit to the final approach, after which you’re established on the glidepath and proceed to the runway on the final segment. The Final Approach Fix is used for non-precision approaches where the final segment starts at a fixed fix on the approach course, Initial Approach Fix marks the start of the approach sequence, and the Missed Approach Point is where you go around if the required visual references aren’t in sight. So, the commencement of the final segment on a precision approach is the Final Approach Point.
