treadigraph,
Thanks for the link to the '71 magazine. While we're on the subject of panels, look at the magazine advert for the Bellanca Viking. It's advertising the panel as being must up-to-date. I have to say that the distribution of the instruments is most definitely NOT what we'd expect to see today. The DI and AI are transposed, the ASI is where the turn co-ordinator would normally be and the TC itself is in the middle of the panel, about where you'd find the transponder! I guess we've come a long way in 45 years...
