Hi everyone, today I took my CMEL oral. My examiner and I had to stop the oral and finish it off tomorrow morning due to time constraints. We covered most of the material but we are going to go over factors affecting Vmc along with critical engine factors and other performance questions. I have most everything down solid but there is one thing I can't remember for the life of me. I know when the C.G. moves aft Vmc increases. What I can't remember is why is it that performance increases with the aft C.G. when single engine. It might sound simple to you guys and girls but for some reason I just cannot remember and can't find a good explanation in any of my text. Please help me out! Thanks!
