The following limits were defined earlier.
QUOTE:
V1>Vmcg
Vr>V1
V2>V1
(if you ignore the possibility of some of these being "greater than or equal to")
The regs also require V2>Vmca
UNQUOTE
If Vmca is less than Vr, then we begin flying at a speed which guarantees controllability in the air.
If Vmca was higher than Vr, we begin flying at a speed which controllability in the air is not guaranteed.
(and there could be quite a spread between Vr and V2; this leaves a grey area, as the regs state Vmca must be less than V2, but not by how much)
e.g. Vr = 120
V2= 135
Then Vmca could be 134. What happens between 120 and 133?
