There is a cure for spatial disorientation: As a last resort, look only at the SAI, avoid sensory overload by ignoring flashing lights, voice alerts, bells, horns, clackers, tones, chimes and whistles, then level the wings, raise the nose ten degrees, add a handful of power and maintain attitude. It works in a dark cockpit, with CADC and static system failure, and with all generators gone on vacation, in IMC.
If each recurrent simulator training session would include just 30 consecutive minutes of nothing but "hands on" flying during complete electrical failure, with one engine inoperative (without A/P, without F/D, without glide slope)....One would not lose the magic touch of raw data instrument flying during extreme circumstances.
