So much that if I had let go, the nose would have pitched up really fast.
I had to trim 5-6 turns forward before the aircraft was stable. That’s a lot!
So, we have a system that brings the aircraft out of trim, and trims when it is not supposed to trim.
Not super easy. Dangerous. I don’t think about this when I fly manually since the first thing I do is to trim forward in order to cancel out the STS.
This system is plain stupid. Try it, and see for yourself.
Who told you to fly like that?
When you accelerate, you apply forward pressure to the control column, and trim out that pressure with forward trim as it accelerates. This forward manual trim stops the speed trim for a bit. Try it, and see for yourself.
