What is required for identifying the Missed Approach Point (MAP) on a localizer approach?

Identifying the Missed Approach Point (MAP) on a localizer approach is crucial for ensuring safe navigation if visual reference to the runway is lost. The use of Distance Measuring Equipment (DME) or radar provides the necessary positional information to determine the MAP accurately.

When utilizing DME, the MAP is typically defined at a specific distance from the approach fix or the runway threshold, allowing pilots to know exactly when to execute the missed approach if they have not established visual references. Radar can also provide essential information, especially in instrument flight rules (IFR) conditions where visibility is limited. Pilots can receive real-time positional updates, which aid in confirming that they are at the correct location for the missed approach.

This option encompasses both methods of determining the location of the MAP, making it the correct choice. Understanding how to properly identify the MAP using DME or radar is vital for pilots, especially in scenarios where visibility may prevent visual identification of the runway.
