john_tullamarine,
the exercise might become even more interesting, if the F/O is PF and, according to SOP only the captain can abort the takeoff, plus add, for whatever reason, a V1-reduction
. A lightweight 37 on a full thrust t/o will become airborne quite early (already when rotating thru around 5-6°), which will give you about 1 second to notice(!) that something is not right
.
Would be a VERY untidy RTO indeed...
