• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

So long Bombardier jets..............

Well, we already knew that.

...but then I work in Belfast and have, at one point, worked in Short Bros. That was the first time I ever came across a Lear 35 in build - white spaghetti hanging down everywhere. I've always wondered why avionics wiring is always white.
 
The white insulation makes it easy to visually find hot spots, overheating.

As to which is which, each wire is numbered, and that is printed on the insulation every few inches.

It also intimidates and scares away non-certified individuals. That's kinda like carry-aboard insurance.

Hmmm. I rewire motorcycles for a hobby and I can spot an overheated wire of any colour at ten paces.

[Edit] It seems that white was just popular amongst manufacturers, but a shedload of aircraft now have multicoloured wiring looms.

They use the white wire so the Tech Reps can tell the techs "I know what the problem is. It's the white wire!"
I kid you not. That's what the Westinghouse Tech Rep told us when I was in the Corps.
He didn't like it either, though.
Not a one of them was labeled in any way, either. Not in military planes, anyway. Had to use the wire listings in the pubs from the company, and hope they had been modified to reflect any changes to the planes.
Worst was the VTAS computer. The bottom of it was a rat's nest of, you guessed it, white wires. Wire-wrapped onto posts, not soldered onto pins. Little small, like 24 or 28 Ga wires. Not labeled in any way. Even if you could see the bad, burnt, wire, it always seemed to be the bottom wire on whatever post it went to. You'd have to unwrap the wires above the bad one, replace the bad one, then replace the others. No way to wrap them back on. So one bad wire could lead to a few dozen other wire replacements, since any wires above the wires to be replaced had to be unwrapped and replaced too. Fun, fun, fun...

Have fun all!
