"...there is ample indication on other threads to support the theory that the crew were presented with information from their instruments and warning systems which was contradictory and confusing."
OK, suddenly no A/P, no A/T, erratic air speed indications, and sensory overload from multiple sources at night in IMC in turbulence at FL350. . . So what?
Zero excuse for an inability to
manually maintain configuration: Keeping present cruise thrust set, maintaining cruise attitude (typically 2.5 degrees nose up) . . . by just looking at (and trusting), the self powered standby attitude indicator. Instinctive. Elementary. Nothing more to do until out of the turbulent weather.
Instead, one overwhelmed P/F reacts by saying: "I Have Control" and pulls the stick, climbing 3000 feet into a stall.
