How do real life rockets to gravity turn

@crowxe Yup, because 1970's computers were not fast enough to consider atmospheric parameters.

@AnotherFireFox so in short the shuttle starts pitching down from the beginning regardless to atmospheric density and no prograde ?

@crowxe The video also says Space Shuttle's ascent guidance system doesn't take the atmosphere into account at all, which means it started to pitch down from the very beginning. This implies he didn't make the follow prograde phase with an algorithm. I guess you can just pick a random altitude high enough to start pitch down.

@AnotherFireFox I get the concept, let gravity turn the vehicle while being prograde and the video says pitch down from prograde when the air is thin, that's kinda loose instructions

@crowxe I believe you misunderstood the concept. Maybe watching this would help you.

Now you force another question, when do we exit the prograde and force pitch close to zero before wasting too much thrust on the vertical component ?

Wow
