What Is Decision Height - Decision height is mostly used in cat ii and cat iii precision approaches and measured using radio altimeter for precise readings, especially for terrain avoidance. Web da, or decision altitude, is defined by the aim as, a specified altitude or height in the precision approach at which a missed approach must be initiated if the required visual reference to continue.has not been established. da only applies to approaches with electronic vertical guidance. Web decision height (dh), the lowest height defined in feet or meters above the ground level (agl) used in precision approaches. Web in a precision approach, the decision height (dh) or decision altitude (da) is a specified lowest height or altitude in the approach descent at which, if the required visual reference to continue the approach (such as the runway markings or runway environment) is not visible to the pilot, the pilot must initiate a missed approach. The decision altitude (da) or decision height (dh) is 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. (icao annex 6) decision altitude (da) is referenced to mean.
