1. DESCRIPTION
This section describes those components used for computing data from a number of different sources
without a preponderance of functions in any one system. This includes the GIA 63W integrated avionics
unit.
The airplane is equipped with two GIA 63W integrated avionics units located behind the PFD and MFD,
respectively. The GIA 63W functions as the main communications hub for the Perspective Avionics system,
linking all system components with the PFD and MFD. The main processor interfaces with all of the Per-
spective Avionics components and performs calculations for the GFC 700 autopilot. The integrated avion-
ics units are not paired together and do not communicate with each other directly.
Each GIA 63W integrated avionics unit contains the following:
•
A 15 channel WAAS certified GPS receiver.
•
A VHF COM transceiver that provides tuning from 118.00 to 136.975 MHz in 25 kHz or 8.33 kHz spac-
ing for 760 or 3040 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.
•
A flight director system if optional automatic flight control system is installed.
•
System Integration microprocessors.
28 VDC for GIA 63W integrated avionics unit 1 operation is supplied through the 7.5-amp COM 1 and 5-
amp GPS NAV GIA 1 circuit breakers on Essential Bus 1. 28 VDC for GIA 63W integrated avionics unit 2
operation is supplied through the 7.5-amp COM 2 and 5-amp GPS NAV GIA 2 circuit breakers on Main Bus
2.
The GIA 63W integrated avionics unit is integral to the Perspective Integrated Avionics system. For an
overview of the Perspective Avionics system, refer to Chapter 42, Integrated Modular Avionics.
