3.3 G1000 COMMUNICATION AND NAVIGATION SYSTEM

The GIA 63(x) IAUs contain the VHF COM, VHF NAV, and GPS receivers. COM and NAV digital
audio is sent to the Audio Panel. GPS information is sent to the GRS 77 AHRS and both displays for
processing. The GTX 33 Transponder communicates with both GIAs in a single transponder installation.
In a dual installation each transponder communicates with its on-side GIA. Transponder data is sent from
the GIAs to the PFD where control and operation occurs. The Audio Panel controls the display
reversionary mode.
