V1 question
And now my opinion:
It's better to continue T.O. with a failure 10 kts before V1; with some 'distinguo' in case the failure is an engine one: What's our weight today? is our a balanced T.O.? which the meteo condintions and the rwy contamination? Is the field elevation high? Are there obstacle in the T.O. path?.
Never abort T.O. (10) any single kt(s) after V1 for any reason! (Except of course in case of a locked elevator)
