Non-technically, we are all supposed to have a "GO" mentality in these situations - ie - V1 Cut - these days, but next few take-offs,when PNF calls V1 - take a real look ahead and ask yourself, quickly, if you think you could really stop at that point
I have to say that, invariably, for me, the answer has been NO!
So, at a later stage, I have recalculated the take-off, come out with all the original speeds, but I had still decided that I would not have been able to stop in any comfort, in one piece, or still on some firm surface - worrying, innit?
