When approaching a localizer, what is the timing reference used for Missed Approach?

• A. From the initial approach fix to the runway
• B. From the Final Approach Fix to the Missed Approach Point or DME
• C. From touchdown to the decision altitude
• D. From the departure point to the first fix

Answer: (B)

The timing reference for a missed approach when approaching a localizer is defined as the period from the Final Approach Fix (FAF) to the Missed Approach Point (MAP) or Distance Measuring Equipment (DME) reference. This is because the FAF is where the aircraft is typically established on the final approach segment, and the MAP is the point at which the pilot must decide whether to continue the approach or execute a missed approach. Understanding the significance of this timing is crucial for safe navigation and execution of instrument approaches. Pilots must maintain awareness of their position relative to the FAF and MAP to ensure they can make timely decisions based on their altitude, speed, and distance to the runway. Furthermore, using DME allows for a precise distance reference, helping pilots to effectively manage their approach profile and plan their missed approach if required.
