It's been a while, but isn't that V2? ISTR that V1 is the commit speed: above that point you have to take off since there isn't enough runway to abort.

- sokoloff 3y agoV1 is the “takeoff decision speed” (roughly as you describe). Vr is the speed at which rotation occurs. Vmu is the “minimum unstick” speed (the lowest speed at which liftoff is possible). V2 is the takeoff safety speed, which is faster than liftoff speed, and the minimum target speed for initial climb.
