If at or near VMO at that density altitude, with full down trim on the horizontal stab, what back pressure on the yoke is required to maintain level flight? Let alone climb? Is it even possible to maintain altitude under this configuration? Has anyone replicated this situation in a sim? Might it be worth understanding the aircraft's flight characteristics in this particular flight regime before passing judgment on the deceased's attempts to remedy the situation they were presented with?
