What is the primary purpose of the final approach segment in an instrument approach procedure?

• A. To exit the terminal area
• B. To reach cruising altitude
• C. To align the aircraft with the runway and descend for landing
• D. To communicate with ATC

Answer: (C)

The final approach segment is the phase where you bring the airplane into alignment with the runway and descend toward landing. It starts at the final approach fix (or point) and continues to the runway threshold, using the published path—glide slope for precision approaches or the designated descent angle for non-precision approaches—to place you on the runway centerline at the correct height. This segment sets up a stabilized, controlled descent so you can land smoothly. Exiting the terminal area, climbing to cruising altitude, or simply talking to ATC aren’t the primary purposes of this segment; its purpose is specifically to align with the runway and descend for landing.
