Vr may not be less than
V1
Vr may not be less than
1.05 Vmca
Vr may not be less than
A speed that allows V2 by 35’ above the takeoff surface after an engine failure at V1
Vr may not be less than
A speed, if rotated at max rate, will result in Vlof not less than 1.1 Vmu normal OPs, 1.05 Vmu 1-INOP
Vr may not be less than
A speed that will not increase TODR to 35’
If
Rotations is initiated 10kt before Vr normal ops
Or
Rotations is initiated 5kt before Vr 1-INOP ops
The lower limits of V2 are
1. 1 Vmca
