This thread is impossibly iterative, and requires, imo, a lot of leeway in particular opinions. For example, SmilinEd said ages ago that a/p in turbulence may need a look see. It may not keep up with its own mission, relative to trend, and rapidity of surface deflections required, which may not be appropriate. Airbus strongly recommends using the a/p at all times, and each operator generally demands the same of each flight crew.

Is there an "EASY!" switch on otto? A mode that will tolerate serious bumps and puckering ride in patience, while anticipating some relief soon?

AF447 was in the bump city, by BEA portrayal, via Captain duBois. Yet the crew remained in a/p, as expected, and when it quit, there was the mundane handover, "I have the controls". No big.

The THS' jackscrew works fine, it is appropriate for a large airliner that needs gentle and deliberate deflections. That it took sixty seconds to travel from three degrees to thirteen seems appropriate for its size, that of a large dancefloor used to manipulate 150 tons of mass.

Without assigning any rating to each post, relative to experience and knowledge, my goal is to be critical of the failures here in man and machine, and learning as much as possible in the process. Please continue to correct where necessary,
