The minimum AP use height for a non-precision approach corresponds to which altitude reference?

• A. Decision Height
• B. MDA
• C. DH
• D. VD

Answer: (B)

Non-precision approaches use a minimum descent altitude as the altitude reference for their minimums. This is the level you may descend to on the approach, but you must remain at or above it until you have the required visual references to continue to landing. There is no glide slope or formal decision point like on precision approaches, so a decision height isn’t applicable here. That’s why the minimum autopilot use height on a non-precision approach corresponds to the MDA. The other terms—Decision Height (DH) and its abbreviation—are associated with precision approaches, and VD isn’t a standard reference for this context, so they don’t fit.
