thread drift here, sorry
Guys, humour me - Can't you set a target vs, leaving you in no doubt as to your present and future position on the profile, and control the speed with thrust and if necessary spoilers? Open descent is a speed lock at idle in essence right? So if you're going to control your descent rate with changes in that locked speed or by the addition of drag you've got a delay before that rate of descent achieves and stabilises, and also the original problem asked earlier - what will the rod actually be? Seems like a bit of a potluck way of doing it to me. I've understand there is more to it than I'm appreciating right now, somebody care to enlighten me?
