So S.F.L.Y., please tell us what you would have done so we can benefit from your superior knowledge!
It's not that I'd have done better, I might have done the same, but since it's far from being optimum I'm interested to know why I would have adopted an underperforming strategy.
This was already discussed in the other thread, if you consider Vref close to best glide speed, variations will deteriorate the performances. Since the AP was constantly increasing the AOA to maintain a wrong path, gliding performances were constantly reduced until reaching their minimum (stick shaker). By reaching the stick shaker they basically reached the worse gliding performances they could achieve below Vref...
