Hmmm, I'm looking at the traces now but I have some difficulties spotting the point where 2s of Full ND input are applied. Could you direct me to it?
I do see one short spike of half ND input and later one very short spike of 3/4 ND. What is my mistake?
Edit: I think I see which part of the trace you are referring to.
2:12:32 ?
If you look at the other elevator angle changes you will notice that they don't change very swiftly, even in the NU direction.
It took ~5s to get from 15° to 30° NU elevator angle.
Also not every single movement of the SS is followed by a dramatic change in elevator angle (or any at all). So the speed and onset of elevator angle change seems pretty much consistent with the other angle changes. There is quite some dampening visible in the traces between SS input and elevator movements.
I attribute the magnitude of the slow reaciotn to the ND input you mentioned also to this dampening.
The elevator movement slows down when the ND inputs reduce/cease so it is difficult to predict how far and how fast the elevator would have continued to move from this relatively short sustained SS command.
As I said before: You will not come to a generally accepted conclusion as to what would have happened had they continued to command full ND.
I stand by my tendancy to conclude that the elevator would have moved to a clear ND position. As you would expect even for an Nz law. It just doesn't happen in 2s.
