IO540, I appear to have touched a nerve, sorry about that. My point is very simple, the handling of an aircraft does change dependent on where the C of G is. That is a fact. The envelope in the POH is a demonstrated RECOVERABLE envelope. The further aft the c of g is then the aircraft will be more sensitive in pitch.... We are not all super human pilots, and we sometimes make mistakes. Why deliberatly (for the sake of a very small increase in economy) take away a factor of safety? If we talk of extremes, look at the Pitts S2A, with C of G at the forward point of the envelope spins recover almost instantly (with correct control inputs of course) at the rear point it takes nearly a turn before it recovers. It also has a significant influence on flick roll entry. But of course you are very aware of all this - is the low houred PPL, who is reading this forum to expand their knowledge so aware?
I think we can all learn something from each other, however its hard to understand why someone gets upset when questioned? Dont forget that with things you take for granted because of your experience, others may not have yet reached that level of experience.
