How can a pilot recognize the missed approach point on the LNAV/VNAV approach?

During an LNAV/VNAV approach, the missed approach point is identified by reaching the LNAV/VNAV Decision Altitude (DA). This altitude is crucial as it serves as a predetermined altitude at which the pilot must decide whether to continue descent towards landing or initiate a missed approach if the required visual references to continue landing are not in sight.

The use of a Decision Altitude is essential because it provides a specific point within the approach where a decision must be made, ensuring that pilots have a clear, standard reference for when to execute a missed approach. This is particularly critical in RNAV (Area Navigation) approaches that utilize vertical guidance through VNAV capabilities.

By contrast, other mentioned points, such as the Minimum Descent Altitude (MDA) and the final approach fix, do not serve the same function in an LNAV/VNAV context. The MDA is relevant for approaches without vertical guidance and doesn't involve a decision point; instead, it marks the lowest altitude that can be flown in a non-precision approach. The final approach fix is an important waypoint on any approach but does not indicate the specific decision-making moment for a VNAV-guided approach where a DA is designated. Thus, reaching the LNAV/VNAV Decision Altitude clearly
