1 Overview

The GIA 6300 is an integrated avionics unit meeting robust environmental requirements. The major
functions of the GIA6300 are:
• Communications Hub and Data Concentrator,
• VHF digital COM (118 - 152 MHz; extended frequency range),
• VOR/VLOC and GBAS receiver,
• Glideslope receiver,
• GPS SBAS receiver,
• Audio Selection, and
• Marker Beacon Receiver.
• Other functions such as AFCS (Flight Director) have significant portions of their
processing executed by the GIA 6300.
The GIA 6300 is designed as though the functions are spread out across a federated system. This
provides independence and redundancy between the functions.
