GIA 63W Integrated Avionics Unit
Original GIA 63W(s) Reinstalled
No software or configuration loading is required if the removed GIA is re-installed in its original position
(GIA1 and GIA2 in their original racks). This does not include units that were returned for repair as their
software and configuration files are deleted during the repair testing process. Continue to the return-to-
service checks in Section 8.
Original GIA 63Ws Swapped for Troubleshooting
No software loading is required if the originally installed GIA units are re-installed in opposite positions
(GIA1 and GIA2 in opposite unit racks). However, configuration loading is required. See Section 3.9,
and then continue to the GIA 63W Test (Section 7.3.1).
New, Repaired or Exchange GIA 63W(s) Installed
If a new, repaired or exchange GIA 63 is installed, the correct software and configuration files must be
loaded to the unit. See Section 3.9, and then continue to the GIA 63W Test (Section 7.3.1).
7.3.1
GIA 63W Test
GPS Signal Acquisition
Figure 7-3, AUX – GPS STATUS Page (MFD)
The GIA 63W units should normally acquire a GPS navigation solution within 5 to 10 minutes of startup,
provided the aircraft is outside (or indoors with a GPS repeater). Select the GPS STATUS page on the
MFD (4th page in AUX group). Two softkeys on the bottom of the display allow the user to toggle
between GPS 1 and GPS 2. Verify that both receivers show 3D DIFF NAV on the MFD.
Continue to the VHF COM Interference test.
NOTE
It may be necessary to temporarily disable or move away from GPS repeaters while
testing, as repeaters may adversely affect GPS receiver performance.
