Very interesting.
Does the A350 really allow the decision making control to be totally in the hands of the computers for an abort when it computes the runway is too short / acceleration rate is insufficient to achieve the required speed in the remaining length?
Is this a computer decision up to v1, or just to, say, 80 knots, which I could possibly understand, or is it just a synthetic warning that the pilot has to action at all speeds?
I don't like some of the Airbus philosophies that take control away from the pilots, warnings I don't mind.
In this case, it seems to be quite an early abort decision, in that they apparently weren't going that fast by my eye.
It will be interesting to see whether human factors were involved here, as at Miami, in the performance calculations, interpretations thereof, etc.
