One comment I received suggests it would move nose down faster than it had moved to full nose up.
It drives the same speed in both directions, but from it's zero point it's got further to go nose up than it does down.
One of the tests we do on the THS involves testing it's auto function as well as that it'll stop auto-functioning when the wheel up front is held. We position a man in the tail to verify a valve moves to close and the THS actuator stops.
