It's easy to tell when a shop is deep into avionics wiring - at least it is in my shop! I generally start by hooking each wire up and one end and then estimating the length of each wire run. I then add about 10% to my guess, just to make sure that I won't come up short when attaching the second end to its destination - an inch too short is just aggravating. But that extra length always ends up somewhere, and that somewhere is the shop floor. Bits and pieces of wire, pitot/static tubing, masking tape (used to temporarily label wires) - and lots of pink or orange wire tires. Continue reading "Wiring Time!"
Way back in my career as a NASA engineer, I spent most of my time training. You see, I wasn't a design engineer - I was an operations engineer - we got to take all the cool stuff that the rest of the aerospace industry built, and make them fly. Much of that work was operating and troubleshooting systems, and part of the job was learning how to fix things "on the fly" so to speak - including things that were never designed to be fixed in flight. Did you ever see the scene in the movie Apollo 13, when they had to make square CO2 absorber cartridges fit round holes? That successful effort lead to an entire discipline in the Space Shuttle program, and we all got a chance to learn the procedures for re-wiring, troubleshooting, and replacing avionics boxes in flight.

Builders who have wired their own airplanes know that you can't always use factory color-coded wire. And yet there are times when it would be handy to mark part of the wire run for later identification. That's where the new Bogert Wire Marking Tool comes in.
According to the company, this a non-conductive nylon tool and a Sharpie permanent marker are all you need to add identifying stripes to 24-8 gauge wire. Continue reading "Bogert Introduces Wire Marking Tool"
