Ok, I am going to be the first to put my hand up and say I dont get this. I have only just started to study aircraft performance though.

I thought moving weight aft, moved CoG aft and therfore you need increased elevator input to keep the aircraft level. Just found this: Effect of Load Distribution but I need to go digest it a little longer.
