Sounds like my Air Force days, though admittedly we had a whole bunch of systems you could never depict on just one fold-out page. The aircraft I spent the most time flying and working on, the RC-135, had almost all of our systems interconnected, so it wasn't possible to depict a single system in some cases, even on multiple pages. As much of a pain as that was, thinking about it does make me nostalgic.You guys should see the wiring diagrams for the newer Cessnas. Instead of showing each circuit on its own page, they have multiple circuits on each page, and each page deals with a section so you need to be flipping back and forth endlessy when trying to trace a circuit. Those airplanes have six busses, too. Troubleshooting is no fun.
