Hi Takata,
Just a brief note, my assumption is that the trim initially traveled slowly nose up and began to really move as the aircraft approached the stall. I do not attribute the nose up attitude to the trim as some are wont to do, it was merely the result of more nose up input than nose down input from the SS, averaged over time-that and what must have been a completely fouled up scan.
Is there any sort of pitch indication adjust function on the PFD? The PF's control inputs act like he had an erroneous level flight pitch setting. I am strictly a steam gauge guy so I've never had the opportunity to see how the other side currently lives.
