With reference to somatogravic illusion, without visual cues:
- Can a steadily increasing pitch-up, of the degree experienced by 447, be misinterpreted as acceleration?
- Can the deceleration of the aircraft (either by the initial speed reduction to M0.8, or the slowing resulting from the climb) be misinterpreted as pitch-down motion?
- If so, can the combination of the two - when taken with rapid vertical speed and altitude loss - be sensed as a steep dive instead of a pitched-up fall?
