You won me until the comment re Vmcg. Very much dependent on crosswind, the actual book figure depending on the cert basis.
If you are at the maximum crosswind and the "wrong" side fails around book Vmcg .. then you WILL find yourself well BELOW the real Vmcg for the conditions .. depending on the configuration, think something in the range 0.5-1.3 kt/kt increase on the book figure. Ergo, tiptoe gyrations in the tulips ...
