Salute!
Guess we are heading toward a sub-thread about the "STS" and all the concerns about how much automation you can handle and how to revert to manual flying unless in an Airbus.
And then there's all the "sub-modes", the reversion sequences, what is working versus what is not, and so forth.
The Boeing is not an Airbus with 100% fly by wire. But it appears that a few systems have "help" from HAL..
And the STS is one
Looks like the STS implementation feeds back to the controls to provide some kinda force feedback. Wonderful. But if that system is corrupted, then you might feel something the opposite of what the aero conditions are normally telling you.
For now, I am sticking with a combo of erroneous air data and a mechanical problem with the stab.
Gums opines...
