“...what does this mean? Why is this search so difficult?”
Because the system is proprietary?
wiedehopf: Are we not discussing the accident? If the tailplane is automatically trimming nose down due to (erroneous) and high AoA, and making nose up more difficult, until the Pitch cannot be overcome by elevator, that seems to me to be opposite to operators’ inputs. The “expected” feel is not “heavy”, making it opposite to (expectation of) manual control feel, no?
Explain your reference to “stall”? That was not the pilots problem. Their issue was inability to climb, not stall recovery. Right?
