Experience in many accidents has shown that pilots tend to abort the
T/O even at speeds slightly above V1. Asked, why they had done this,
they didn't have an explanation or stated something like "#3 had failed,
so I suspected that #4 had failed too". I think that there is a
psychological barrier. One doesn't want to take off with an
unhealthy plane. Men want to keep their feet on the ground.

I predict, that most pilots don't want a computer to decide whether
to abort or continue a take off. On the other hand, there aren't many
exceptions to the rule "before V1 stop, after V1 go".

I have no doubt that AI wouldn't hesitate to build such a device
in its planes to make them more "pilot proof".

I think that such device could assist the commander in making his
decision by not just saying "ding, ding, ding" but give a more
distinct warning like "engine 2 flameout, everything else ok. Please
