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. (Refer to
42-00)

2. TROUBLESHOOTING
Trouble Probable Cause Remedy
NAV1 or COM 1 not receiving
valid data.
Software or configuration error. Check PFD Alert Window for GIA1
configuration, software, or failed
data path error messages. Correct
any errors before proceeding.
GIA 63 integrated avionics unit is
offline.
Swap GIA1 and GIA2 and recon-
figure for new positions to verify
location of problem. If problem fol-
lows GIA1, replace GIA1.
Check Ethernet interconnect from
GIA1 to PFD and unit connector
pins for faults.
If problem persists, replace PFD.
NAV2 or COM 2 not receiving
valid data.
Software or configuration error. Check PFD Alert Window for GIA2
configuration, software, or failed
data path error messages. Correct
any errors before proceeding.
GIA 63 integrated avionics unit is
offline.
Swap GIA1 and GIA2 and recon-
figure for new positions to verify
location of problem. If problem fol-
lows GIA2, replace GIA2.
Check Ethernet interconnect from
GIA2 to MFD and unit connector
pins for faults.
If problem persists, replace MFD.

EFFECTIVITY:
GPS INTEG or Time not receiving
valid data.
Software configuration problem. Check PFD Alert Window for
GIA1/2 configuration, software or
failed data path error messages.
Correct any errors before pro-
ceeding.
External interference from nearby
objects.
Check for possible external inter-
ference to the GPS receivers.
1. Verify the aircraft is located
where the GPS antennas have a
clear view of the sky.
2. Ensure that a cell phone or a
device using cell phone technol-
ogy is not turned on (even in a
monitoring state) in the cabin.
3. Turn to the MFD AUX – GPS
STATUS page and check the GPS
strength bars on both GPS receiv-
ers. If the signal strength levels
are erratic, disappear and reap-
pear rapidly, or switch between a
solid and hollow bar frequently
there is an external device interfer-
ing with the GPS receivers. Turn
off any devices that radiate a sig-
nal in the local area or move the
aircraft to another location to
remove the interference.
4. Verify the aircraft is not parked
in close proximity to a hanger with
the doors open and equipped with
a GPS repeater.
GIA 63 integrated avionics unit is
offline.
Verify the GIA’s are online by
checking for a green checkmark
next to the GIA on the MFD Aux –
System Status page.
If a GIA is not online (a Red-X will
be present instead of a green
check mark), check for power
input faults.
Refer to the GIA GPS Trouble-
shooting Section for additional
actions.
