Ahh Brian, talk of modern kit. I remember SCINS being introduced on the SF frames toward the end of my time. GE's were given a pamphlet describing operation and component parts, then sent off on 4 week SF dets, hopefully armed with enough info to fix it if it went tits. Never had one break, and thanks to one particular Nav I certainly learned how it all worked. Modern Nav stuff is a doddle, it has to be, pilots operate it.
