C. Digital Data Inputs
(Ref. Fig. 004A)
The Enhanced GPWC receives serial digital data inputs from:
-radio altimeter transceiver 1 (radio altitude),
-Air Data/Inertial Reference Unit 1 (ADIRU),
*
ADR portion (barometric altitude, barometric altitude rate, computed airspeed),
*
IR portion (latitude, longitude, magnetic heading),
-Multi-Mode Receiver 1 (MMR) (glide slope deviation, localizer deviation, selected runway heading),
-Flight Management and Guidance Computer (FMGC) (latitude, longitude, track, navigation modes),
-Centralized Fault Display Interface Unit (CFDIU) (command word, date, flight number, UTC),
-Flight Control Unit (FCU) 1 and 2 (CAPT and F/O ranges),
-Weather Radar 1 and 2 (hazard busses).

-Landing Gear Control and Interface Unit (LGCIU) (main landing gear retracted or extended),
-ECAM control panel (audio suppression),
-GPWS/FLAP MODE pushbutton switch which, when pressed (in) (white OFF legend on), overrides a flap abnormal condition input,
-GPWS/SYS pushbutton switch which, when pressed (in) (white OFF legend on), inhibits Modes 1 to 5 warnings,
-GPWS/G/S MODE pushbutton switch which, when pressed (in) (white OFF legend on), overrides the glide slope mode,
-PULL UP/GPWS pushbutton switch which, when pressed (in), enables the Enhanced GPWC to perform test,
-GPWS/TERR pusbutton switch which, when pressed (in) (white OFF legend on), inhibits TAD and TCF functions,
-TERR ON ND (CAPT or F/O) pushbutton switches allow the crew to select or deselect terrain display on ND's,
-Weather Radar control unit,
