Your comments reflects back to my earlier question about whether 'seat of the pants' should have been part of the analysis. I didn't fully understand the photos of the PFD in #265. Are these both of the same PFD showing a sequence in display, or are they LHS & RHS? It'll help me understand. As DH asks: if you are in level 1G flight and there PFD says you are in upset flight does your backside not tell you eyes that 'it can not be true'? This is not not about a false level from your inner ear, it's simple g loading on your body.
This situation & experience is a classic simulator training exercise, but in 35 years I've never seen it. It teaches so much: knowing when to sit on your hands; careful analysis of the situation without a checklist; CRM about what to do about it; plus other aspects.
Equally I've never been given blocked static vent (only pitot tube). Simulator being wasted?
