There are an increasing number of people in my company insisting we only stop for fire/ eng failure/ or predictive windshear (and don't like thinking about the variable unsafe to fly area).
The problem I see is the inference that we can set up the RTO planning in anticipation of a guaranteed outcome - ie black and white.
Not the case.
MOST times, if the T/O is rejected up to a margin below V1, the RTO will be successful. MOST times, if the T/O is continued beyond V1, the T/O will be successful.
The bit in the middle has a LOT of caveats attached to its successful outcome. For routine civil airline operations we don't have the time luxury to discuss and try to memorise a tome of information for this takeoff .. we work on the basis of reasonable historical probabilities skewed to the most likely means of achieving a successful outcome.
.. but that doesn't mean that the operation cannot come unstuck if you are near to the tail of the distribution curve on the day ...
