I don't think this has been covered in another thread, but if so, please excuse me. Hello, I'm new to the forums.
The built-in shuttle ascent autopilot behaves seemingly odd, at least to me based on my limited knowledge of STS operations. Particularly, when it comes to altitude. Is it normal that a shuttle launched makes it to 100-110km, and then begins to descend back down to about 75-80km to build up speed and hopefully reach about 7.6k TAS? That's what it does for me. From what I've read, ET sep should occur around 110km, but if I allow autopilot to do its thing, ET sep happens closer to 75-85km. So, other than asking whether this behavior is normal (altitudinal yo-yo-ing), I'll also ask at about what altitude in km should the highest velocity prior to ET sep be reached and in general what should that velocity be? Thank you so much. Orbiter version 2016, by the way.
