Capn B,

I'm always happy to stand corrected. Despite a rather embarrassing amount of exposure to the -9/-80 series, there will always be something I don't know. I'd never heard of such a follow-up on the elevator control mechanism. Just in the interest of intellectual curiosity, would you happen to have a schematic or diagram you can post showing that elevator follow-up mechanism ?

As a further variation on a theme, if the augmenter were removed from the equation (deplete the accumulator, I guess), would pushing the control column full nose down also move the elevators down via such a follow-up ?

POMs have always been rather sparse in such details but time and happenstance will always offer a time when knowing such fine points might have been valuable.
