Glue Ball,
Increasing AOA to stay on the glide until the stick shaker is activated ( what the autopilot did according to the AAIB report ) is definitely not the way to get the best chance of making it to the runway... It is a fact, simple fly mechanics. Stall speed is certainly not the best gliding speed.
Therefore, considering that the plane missed the runway by a reasonably short distance, it is not a surprise that a pilot WHO KNOWS WHAT IS GOING TO HAPPEN, i.e. that the thrust will never come back, could be able to land the plane on the concrete by immediately taking the right speed, slope, and wing configuration. So, i am pretty confident that the simulation may be quite relevant.
That doesn't mean that the real pilots on the real flight were wrong in their actions, they had no way to guess what was to happen in the next seconds...
And in fact, they saved the day by pushing the stick and reducing flaps as soon as the situation became clear.
