Okay--I've searched everywhere, and surprisingly, there is nothing online that shows you how to utilize the old-style navigation systems on the 707. I'm pretty good with FMC's, but as far as the 707's route guidance systems, I don't know INS from Doppler. Yes, I've read the manuals, and I know what everything does, but not how to use it all together, i.e. put enable Doppler, make autopilot follow the route, etc... Thank you!
