Thoughts?
Why would you crash if you didn't make Vr ?
In some cases V1=Vr. In any case, Vr is 1.05 X Vmca. Then, once airborne, V2 is 1.10 X Vmca.
BTW, this stuff is very well covered in the Euro ATPL theory exam if you ever get a chance to view the books.
There's a lot of margin in these V speeds!
I've taken off hundreds of times where, had I gone OEI, my reaching the 35ft screen height at V2 was not assured and I knew it. Even so, takeoff is still legal!
If you abort after V1, you better have a good lawyer, if you're still alive!
If you reach V1, keep going.
