During the LNAV approach, the missed approach point (MAP) is indicated by reaching which waypoint?

In an LNAV (Lateral Navigation) approach, the missed approach point (MAP) is typically indicated by a specific waypoint that is part of the approach procedure. The correct answer, which refers to the RW30 waypoint, suggests that this waypoint is designated as the MAP for the particular approach being discussed. Identifying the MAP is crucial, as it defines the point at which a pilot must make the decision to execute a missed approach if the runway environment is not in sight or if conditions are not favorable for landing.

During the LNAV approach, the flight path is defined by lateral navigation, and it usually includes specific waypoints that guide the aircraft. The RW30 waypoint is engineered as the specific point where pilots must assess their landing options. If weather or visibility prohibits a safe approach, reaching this waypoint signifies that the missed approach should be initiated.

Meanwhile, other choices like RW20, MAP, and APCH waypoints could either represent different positions or functions within the approach and do not specifically indicate the missed approach point as designed in the procedure being addressed. Recognizing the correct waypoint for a missed approach is vital for ensuring safety and compliance with the established approach protocols.
