Thanks for the reply, By George.
Yes, then manual definitively says Vmcg. I suspect the reason has to do with either a)the loss of NWS, or b) a possible reduction in PSI or authority over the rudder. However, my knowledge leaves me short, and so does my manuals.
As for Vmca, yes, there certainly are issues associated with the 2nd segment climb. But the MEL does not specifically mention the Vmca associated with this item.
