On an ILS, the final approach segment begins at the point named what?

• A. Final approach fix / glide slope intercept.
• B. Threshold crossing height.
• C. Missed approach point.
• D. Decision altitude.

Answer: (C)

The final approach segment starts at the Final Approach Fix, which for an ILS is the glide slope intercept point. This is the point where you are established on the instrument approach path and can begin your continuous descent along the glideslope toward the runway. It marks the transition from the intermediate segment to the final approach; obstacle clearance and proper alignment are ensured from this point onward. The missed approach point, by contrast, is a later reference indicating where you must execute a go-around if the runway environment isn’t in sight or the approach can’t be continued to a safe landing. Threshold crossing height is simply the altitude at which the approach path crosses the runway threshold, and decision altitude is the altitude at which you must decide to land or go around during a precision approach.
