ahhhhhh Just slap me in the face John, I flew the 400 for 8 years and believe me I've never heard of VMCA2 we don't have the term in our manuals anywhere.......................ok
I'm just re-reading the FCOM2 for the 400 now and still can't find ANY ref to VMCA2 or VMCG2. The only thing close is 3 Eng ferry flights section where it mentions: The V2 chosen is the higher of VMCA or VMCG ( twp Engines inoperative ) blah blah blah..............
Now I'll look at the FCTM to see if it differentiates 1 or 2 Engines out.
