 3. System Description
__________________
 A. General The Enhanced GPWS monitors data inputs from the navigation sensors. This information is used to provide suitable aural and visual warnings to alert the crew of a hazardous situation with respect to the terrain.
 1EFF : ALL 1 34-48-00Page 8 1 1 Config-1 May 01/05 1 1 1CES 1

 B. Warnings Warnings are generated by the Enhanced GPWC which is installed on the shelf 88VU, in the aft electronics rack 80VU. Aural warnings are broadcast from the cockpit loud speakers.

R **ON A/C 105-105,
 C. Digital Data Inputs
 (Ref. Fig. 004)
 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),
