What altitude must a pilot reach when executing a precision approach?

A precision approach requires a minimum altitude known as the Decision Altitude (DA) to ensure safety and guidance during the landing phase. The DA is the altitude at which a pilot must decide whether to continue the approach or execute a missed approach if the required visual references for landing are not visible.

At this altitude, the aircraft is typically at a point where it is committed to landing, given that a precision approach provides lateral and vertical guidance through an Instrument Landing System (ILS) or similar procedure. Reaching the Decision Altitude significantly contributes to the effective management of landing protocols, ensuring that pilots meet the necessary criteria for safe operations in varied weather conditions.

In contrast, the other options represent different terms or points in the approach procedure but do not specifically indicate the altitude at which a pilot must make the critical decision to land or go around.
