"That would explain the initial NOSE UP"....
If so then, my friend, that is HUGE. Because post "INITIAL NOSE UP", is territory that is covered well by Yourself and F4. A combination of Pilot inputs and g sensitive commands may have nibbled 447's way up to 17PU.
On the graph, with the NOSE pitching down (and the altitude increasing), is evidence of the disconnect between PF, his instruments, the FCS, and the Weather. IMHO.
