In spatial disorientation, the vestibular system rules. The pilot believes they are turning when they’re not and vice versa. The vestibular has overpowered the visual. A pilot makes inappropriate control inputs based upon these false sensations. It’s worth repeating that inappropriate control inputs during an upset recovery can lead to a completely different upset situation. Game over.
The contradiction between sensed orientation and visual in the pilot’s mind creates confusion, and it’s only through training and experience (and dare I say proficiency) that a pilot is able to resolve this. As straightforward as it seems, just making the attitude indicator bigger doesn’t solve the underlying problem.
A similar issue is experienced by many in a simulator, but manifested differently. Even high-end simulators have an infidelity between the motion and the visual. However, when flying a simulator, the disconnect between the senses doesn’t create full blown SD, but rather causes many to become ill. Some even violently.
While there is belief that synthetic vision technology may provide improvements in SD recovery, the real benefit from SV is improving situational awareness, workload reduction (i.e. terrain and path-in-the-sky) AND UPSET PREVENTION.
But why keep asking for meaningless opinions?
