- either of Vmca or Vmcg may be smaller
- V2min must by definition be not more than V2 (you have V2min>V2)
- V1 and Vr may be equal
- Vrmin may be set by 1.05Vmca for some cases (hence Vr>Vmca)
1. sorry about that =) was typing a bit faster than I was thinking... =)
2. I see, how about the faster speeds? I've seen various definitions about speeds that occur at the same point on the scale, for example best range and max range seams to be the same speed. Max Endurance and minimum power also seams to be the same speed...?
