Today, when I was testing my new gravity steering algorithm, I was confused by a problem. When I've got the rocket at a certain speed, it's turning to an angle. Then wait for the rocket to tilt to that angle and use "lock heading on (prograde)". Then I click to switch between "surf" and "orbt" and find that there are two different speed directions, while "lock heading on (prograde)" performs two different direction locking respectively. Although locking is correct. But if I switch between the two speeds during the launch, it will result in two different launch results. This is quite confusing to me, although I can execute this command without clicking on this one and get the launch to the desired result. But I'm still confused by this setting. I would be very grateful if someone would like to extend your warm hand and point out how to let the rocket lock in only one mode direction when switching the display of different speeds. May simple rocket technology give you strength.
