That's true, I shouldn't be using the term "stick pusher" as we don't know what it does at this point. The NG's STS system just uses the autopilot to move the stab trim at a slower rate than the switches on the yoke. Is the new system just some variant of that? Does it move the trim wheel more quickly? Can it be disabled using the stabilizer trim cutout switches?

THe AD says that it trims the stabilizer.

From the descriptions, it's acting in a similar way.

It moves it at 0.27 degrees per second. I have no idea how that compares to the other things that move the stabilizer.

Boeing says you should move the switched to "cutout", but then goes on to say that you might still have to hold the trim wheel to get it to stop.

So it's back to jamming the Capt's knee against the trim wheel, like in the 727?
