The use of speed brake while the flaps are moving can cause a discrepancy where the aircraft flies Vapp+10 kts. You’d indeed recycle the auto thrust to get rid of it. Considering that it’s a “bug” it happens surprisingly often. It’s in the 319 only. The only reference I have is to our own OMB however.
For the ground speed mini fans; there’s been a subtle but significant change in the logic comparing the NEO to the CEO. The NEO only adds a third of the difference in wind, compared to the whole difference on the CEO.
