4.6 Installation Considerations
The GIA 63W interfaces with the G900X/G950 system and with various avionics equipment. Fabrication
of a wiring harness is required. Sound mechanical and electrical methods and practices are required for
installation of the GIA 63W. Refer to Section 13 for Shield Block information and Appendix F-J for
system interconnects.
4.6.1 GIA 63W Minimum Installation Requirements
Below is a list of required devices for TSO-C145a category Class Beta 3 certification.
Manual Course Device
This device delivers the manual course select to the GIA 63W, which is required for the VOR receiver,
and optional for the GPS receiver. Course information can come from an analog resolver, or from the
GDU PFD/MFD via Ethernet HSDB.
GDU PFD/MFD
This device displays Nav Flag, Left/Right, To/From, Glideslope Flag, and Up/Down as well as integrity
messages. In addition it provides manual course selection to the GIA, which is required for the VOR
receiver and optional for the GPS receiver.
