Hi Guys

Sorry if this subject has already been broached but I searched and could not find it! I am busy studying for a tech interview and have been advised this question may pop up? Does anyone have any thoughts or references I could look up?

Thanks in advance,

Isn't VMCA (min control speed air) always higher than VMCG (min control speed ground) on all aircraft?

all came up with a simple search on the term VMCG (http://www.pprune.org/forums/search.php?searchid=625891) .... and those all specifically refer to this very common - and in my opinion utterly stupid - interview question.
