I must be missing something about the flight control laws and the A/P.
Seems to me that A/P disconnect should result in stick commands to the system and not keep the jet rolling or pitching up or.... using last commands from Otto. In other words, no stick input then zero roll rate command or change in Nz from the basic control laws. Almost an "attitude control" mode.
So some here have advocated " don't just do something, just sit there".
My own experience in our primitive FBW jet ( have to bow down to Doze-breath about our system, heh heh) was the sucker handled turbulence really well if you simply relaxed pressure on the stick. In fact, at low level and 500 knots over the thermals the sucker felt more like an Aardvark than the light jet it was. The computers smoothed out the ride like you would not believe.
So question is: does HAL keep commanding the last A/P inputs or not?
