Decision Height
A decision height (DH) or decision altitude (DA) is a specified height or altitude point/level used as a reference. This altitude specifically state to which type of altitude a pilot is referring to.
DECISION HEIGHT - With respect to the operation of aircraft, the height at which point a decision must be made during an instrument approach to either continue the approach or to execute a missed approach [abort].
Decision Height (DH): The height at which a decision must be made, during an ILS or PAR instrument approach, to either continue the approach or to execute a missed approach. (FAR Part 1) ...
DECISION HEIGHT (DH) - The height at which a decision must be made during an instrument approach to either continue the approach or to execute a missed approach.
[edit] Decision Height or Altitude
A decision height (DH) or decision altitude (DA) is a specified height or altitude in the precision approach at which a missed approach must be initiated if the required visual reference to continue the approach ...
Decision Height
dihedral
Angling of wings or tailplanes upwards from root to tip when seen from head on, to achieve lateral stability.
Decision Height - Height at which a missed approach must be executed if the required visual reference to continue the approach to land has not been established ...
DECISION HEIGHT- With respect to the operation of aircraft, means the height at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.
DECISION HEIGHT When flying an aircraft, the height at which a decision must be made during an instrument approach to either continue the approach or to execute a missed approach (abort).
Decision Height (DH) / Decision Altitude (DA)
With respect to the operation of aircraft, means the height or altitude at which a decision must be made during an ILS, MLS, ...
The decision height (DH) is the lowest altitude to which we can descend on a glide slope. At this altitude you much either execute a missed approach or land, depending on the visual landing environment.
DH - decision height. The height on a precision approach at which a pilot must have the runway approach lights in sight to continue the descent, or if not, must initiate a go around.

Facility providing operation down to 100 feet decision height and runway visual range not less than 1200 feet.
If we reach the missed-approach point or decision height and haven't broken out, do not expect me to say anything at this point. I want you to decide on your own when it's time to begin the missed-approach procedure.
It indicates to the pilot, both aurally and visually, that the aircraft is at the designated decision height (DH), normally 100 feet above the touchdown zone elevation, on the ILS CAT II approach. It also marks progress during a CAT III approach.
Category IIIa operations, an ILS approach and landing with no decision height (DH), or a DH below 100 feet (30 meters), and controlling runway visual range not less than 700 feet (200 meters).
