Yellow : Elevator movement commanded
Green : THS begins following movement (autotrim)
Unfortunately the inputs are never held long or forcefully enough for the THS to make significant movements (remember it took over a minute of nose-up to go from cruise settings to full-aft), and the nose-down elevators last for 10-15 seconds at most - crucially they are immediately followed by a return to nose-up
could you point me to the indication, that the THS is moving? THS is the blue straight line on the bottom?
But by chance, how should THS move when after 15 sec. of SS ND the elevator peaks max at -15°NU (the magenta line)? Would the THS start moving prior elevators move to the ND range? How long is SS ND and in what magnitude required to get the elevator in a ND position?
