Thanks for that, I can find no mention, in the certification standards, of Vmca. Since it seems so widely used there must be an authoritative statement somewhere that says if you establish Vmc as required by the certification standards you can call it Vmca.
As you would know the procedures for establishing aircraft performance speeds are described in great detail in the FAR's and amplified in various AC's.
Anyway this is clearly the wrong place for this discussion so I will desist.
