Re failing for 1 knot below V2 on the eng fail profile , you would need to get the definitive answer from a TRE but i believe it is a mandatory item , allowing the speed to decay below V2 is a real serious matter , especially an a swept wing aeroplane .
Have seen a couple of guys being asked to repeat the SE profile in my current mob (EZY) for doing the same thing . Both the TRE's were total gents , this item however was non negotiable .
