During an ASR approach, what is the potential error range from the runway edges at the MAP?

In the context of an ASR (Approach Surveillance Radar) approach, the potential error range from the runway edges at the Missed Approach Point (MAP) is vital for ensuring safe and accurate navigation during the approach. The correct answer reflects that the typical lateral deviation that could occur is approximately 500 feet from the runway edges at this critical decision point.

Understanding the potential error range is particularly important for pilots when assessing their positional awareness and situational response during instrument approaches. Knowing that there is a 500-foot potential error enables pilots to plan their missed approach procedure more effectively, ensuring they maintain safety margins and are prepared for deviation from the intended flight path.

Other options present larger distances that do not align with the standard operational tolerances established for ASR approaches. A smaller potential error range would not account for the complexity and inherent inaccuracies in radar systems when landing at higher speeds or in variable weather conditions. Hence, the 500-foot range is the established and recognized standard for this type of approach.
