Q

Describe the Garmin Integrated Avionics Unit

GIA 63H

A

2 GIA 63H
Functions as main communication hub linking all LRUs (line Replaceable units)
Each contains a GPS SBAS receiver
- Space-based augmentation system(includes WAAS)

Each GIA 63H contains VHF com/nav/gs receivers, and a flight director (FD) and system integration microprocessors

Each GIA 63H is paired with a respective GDU 1040H via HSDB connection

GIA 63Hs are not paired together and do not communicate with each other directly
