My understanding is the drawings are specific to the WAAS upgrade. They mention removing existing GIA 63 LRUs, which wouldn't be the situation in a new build. Regardless, the coax in my plane is the required double shielded coax. I do have new antennas, but nothing was done to my ethernet wiring assembly. That's not mentioned in the drawings, so I'm not sure why it would be required.Charles K wrote: ↑Wed Mar 09, 2022 4:11 am I might be wrong here - but these drawings are general for the new plane build and not specific to the upgrade. I'll have to dig up the paperwork I have but I believe new antenna cables and ethernet wiring are a part of the install kit.
Cannot find anything specific on paperwork but it is possible that the coax required for the WAAS is different than for non WAAS. All I know is that I have new antenna cables and a new ethernet wiring assembly that included an all new lightning protection resistor board as well. Have had no RFI issues.
Which version of the GIA 63W do you have? I have the -20 model. Perhaps this is a wild goose chase, but the STC mentions relocating the GTX 33 transponder "outboard" of the equipment rack when the -20 GIA 63W is installed. Nobody seems to know why this is. Of course, I don't have the GTX 33, I now have the GTX 345 like you, but am wondering where your transponder is located. Is it in the former position of your GTX 33, or has it been moved "outboard", whatever that means?
