Curious to know what the benefit of auto take-off would be..?
Well, after almost every accident there are a few "Dr Stangelove" type engineers that run to propose automated ways to eliminate the problem.
Wrong manual calculation/selections of Vspeeds , tail strikes and wrong runway/intersection take offs are some of the candidates used to justify the study.
Their argument is that the basic technology already exists (e.g used on the Global/Euro Hawk )
