I GET IT!

Everybody talks about things like CG and thrust ratios, but I've never heard of Center of Pressure before. The sports car and weather vane analogies helped.

I was thinking of this force as the thrust factor, but it's not that at all. It's the point where all the forces ACTING UPON the airplane trying t o move it in yaw and pitch are centered (roll would be an entire lateral axis nose to tail, right?). Of course you'd want that behind the CG.

Thanks Bax. Very interesting.
