The similarity between the crashes appears to be flight director operation and only selecting one off.

In the Asiana case, based on company SOP's for a visual approach, both FD's were supposed to be selected off(in order to change the A/T mode to SPD which would cause the A/T to adjust to maintain the selected speed) and then one selected back on(this allows for the F/D to continue to be displayed throughout a go-around). But instead, only one F/D was selected off with the other remaining on(instead of being selected off then on), allowing the throttles to stay where they had been placed(idle) regardless of indicated airspeed.

From what I can tell, it seems that the Airbus is the same way or very similar. Is that correct.
