D+D = Distress + Diversion D-ATSU = Downstream-Air Traffic Services Unit D/A = Digital to Analogue D/C = Down Converter D/F = Direction Finding D/L = Data Link D2 = Direct To D2D = Design to Distribution D4 = USA Framing D8PSK = Differential 8 Phase Shift Keying DA = Descent Advisor DA = Danger Area DA = Decision Altitude DA = Design Authority DA = Designation Address DA = Direct Access DAA = Data Access Arrangement DAA = Direct DAAIS = Danger Area Activity Information Service DAB = Defense Acquisition Board DAB = Digital Audio Broadcasting DAB = Discrepancy Alert Bulletin DAB = Divisional Accounts Branch DABS = Digital Audio Broadcast System DABS = Discrete Address Beacon System (forerunner of Mode S) DAC = Digital Audio Connverter DACS = Danger Area Crossing Service DACS = Digital Access Cross Controlled Services DACS Director Area Control Services DADC Digital Air Data Computer DADI Datalinking of Aircraft Derived Information DAES Directorate of Aircraft Equipment and Systems Development DAF Demand Adjustment Factor DA/H = Decision Altitude (Height): 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 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.
