2.1.7 GIA 63W Integrated Avionics Unit (2)
Two Garmin GIA 63W Integrated Avionics Units (IAUs) contain the VHF COM/NAV receivers, WAAS
GPS receiver, Flight Director, and system integration microprocessors. The GIAs also serve as a
communication interface to all other G1000 LRUs in the system. Each GIA 63W communicates directly
with the on-side GDU 1040A display using a HSDB Ethernet connection. Both GIAs are located
remotely in the nose equipment bay.
GIA 1 receives primary electrical power from the Essential Bus and a secondary electrical power supply
from Dual Fed Bus No.1. GIA 2 receives electrical power from Dual Fed Bus No. 2. The GIA 1’s
COMM power supply (COMM 1) is provided by the Essential Bus. GIA 2’s COMM power supply
(COMM 2) is provided by Avionics Bus No. 1. Therefore, both GIAs power-up immediately with
external or aircraft power or battery operation, with the exception of COMM 2 operation which will
become active after selection of Avionics Master on.
