Ok,

Definitions from Doc 8168

Decision altitude (DA) or decision height (DH). A specified altitude or height in the precision approach or approach
with vertical guidance at which a missed approach must be initiated if the required visual reference to continue the
approach has not been established.
Note 1.— Decision altitude (DA) is referenced to mean sea level and decision height (DH) is referenced to the
threshold elevation.
Note 2.— The required visual reference means that section of the visual aids or of the approach area which should
have been in view for sufficient time for the pilot to have made an assessment of the aircraft position and rate of change
of position, in relation to the desired flight path. In Category III operations with a decision height the required visual
reference is that specified for the particular procedure and operation.
Note 3.— For convenience where both expressions are used they may be written in the form “decision
altitude/height” and abbreviated “DA/H”.

Minimum descent altitude (MDA) or minimum descent height (MDH). A specified altitude or height in a nonprecision
approach or circling approach below which descent must not be made without the required visual
reference.
Note 1.— Minimum descent altitude (MDA) is referenced to mean sea level and minimum descent height (MDH) is
referenced to the aerodrome elevation or to the threshold elevation if that is more than 2 m (7 ft) below the aerodrome
elevation. A minimum descent height for a circling approach is referenced to the aerodrome elevation.
Note 2.— The required visual reference means that section of the visual aids or of the approach area which should
have been in view for sufficient time for the pilot to have made an assessment of the aircraft position and rate of change
of position, in relation to the desired flight path. In the case of a circling approach the required visual reference is the
runway environment.

So we know on a non precision aproach we fly to MDA/H. Not a DA/H!

Thus, the question should be to the agency who publish the plate why they have printed the wrong term in the minima box, should it not?
