The MDH cannot be lower than which reference in a straight-in approach?

Explanation:
In a straight-in approach, protecting the final approach path from obstacles is what sets the floor for your descent. The minimum descent height (MDH) is the lowest height from which you may continue the descent along that path. That floor must never be below the obstacle clearance height (OCH), which is the height that ensures obstacles along the final approach are cleared. If the MDH were lower than the OCH, you’d be descending into a zone where obstacle clearance isn’t guaranteed, increasing the risk of collision. Therefore, the MDH cannot be lower than the obstacle clearance height.
