How should the missed approach point be identified for the RNAV (GPS) RWY 36 approach?

Identifying the missed approach point (MAP) for the RNAV (GPS) RWY 36 approach is crucial for safe and effective decision-making during an approach. The correct method to identify the missed approach point is when the TO-FROM indicator changes. This indicator reflects the transition from being on the final approach segment to being beyond the approach fix, signaling that the aircraft has passed the point where a missed approach should be initiated if the runway is not in sight or if an approach requires discontinuation.

Using the TO-FROM indicator is an important part of RNAV (GPS) operations, as it provides real-time guidance based on the aircraft's position relative to the approach fix. This method is based on the aircraft's navigation database and ensures a precise assessment of position concerning the missed approach point.

The other options may represent relevant factors in approaching a runway, but they do not accurately reflect the protocols for identifying the MAP. For instance, relying solely on altitude (such as reaching the Minimum Descent Altitude) does not provide a clear indication of the spatial position along the approach. Similarly, visual references and specific altitude thresholds like 500 feet AGL may contribute to situational awareness, but they are not definitive criteria for determining the MAP, as these
