Interesting discussion on "unloading" the wing - thanks Machinbird and roulishollandais.
One thing I have mentioned before is the obvious 1.5g as the PF loaded the wing shortly after taking the controls, during which the two brief bursts of SW occurred. At the top of the initial climb the wing was unloaded and 0.75g resulted as the aircraft went over the top in ballistic fashion, to be loaded to 1.15g as he pulled into the final climb and triggering the SW continuously.
The reduction in 'g' as he pulled for the second time was in direct relationship to the remaining CAS, i.e.
1.15 / 1.5 = 0.767 or,
265 * 0.767 = 203 KCAS.
That's not the real point, as it is the crossing into the stall during the 15 secs after 02:10:57, where the aircraft was "ballistic" and continued to gain height as the normal acceleration dropped to 0.8g, is where the real opportunity to change the AoA rapidly and recover airspeed existed. It wasn't to be, and the opportunity to do so became limited after 02:12:00 (IMHO).
