The decision height is 200ft for straight-in ILS 36. What you mean is
the decision altitude. Unless I've misunderstood something completely.


No, I mean decision height. The decision height for the S-ILS 36 is 882
MSL, the height above touchdown is 200 feet.



No...

Decision Height is the height above the touchdown zone elevation.

Decision Altitude is the MSL altitude of the Decision Height.

From the Pilot/Controller Glossary:

DECISION ALTITUDE/DECISION HEIGHT [ICAO]- A specified altitude or height (A/H)
in the precision approach 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 [MSL] 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.
