GIA 64

The GIA 64(W) is a microprocessor-based input/output Line Replaceable Unit (LRU) used in a Garmin
Integrated Flight Deck. The GIA 64(W) communicates with the GDU via Ethernet high-speed data bus
(HSDB), and with other LRUs using RS-232, RS-485/422, and ARINC 429. All configuration is done
through the GDU. The GIA 64(W) contains the following sub-assemblies:

• A main processor that interfaces with all LRUs in the G1000 sub-system and performs
calculations for the GFC 700 autopilot (if equipped).
• A twelve channel parallel GPS receiver that simultaneously tracks and uses up to 12 satellites.
The GIA 63W includes a 15 channel WAAS certified GPS receiver.
• A VHF COM transceiver that provides tuning from 118.00 to 136.992 MHz in 25 kHz or
8.33 kHz spacing for 760 or 2280 channel configuration respectively.
• A VOR/ILS localizer receiver that provides tuning from 108.00 to 117.95 MHz in 50 kHz
increments.
• An ILS glideslope receiver that provides tuning from 328.6 to 335.4 MHz as paired with the
frequency tuned on the VOR/ILS localizer receiver.
