Been reading Chapter 5 of the PHAK and making notes...but I have a question about stability in regards to CG vs. Center of Pressure.
So as CG moves forward, stability increases (although performance decreases across the board due to flying at a higher AOA). If CG moves rearward, stability decreases (but performance increases across the board due to flying a lower AOA - that said stall/spin recovery can be hindered due to a shorter moment arm).
The above all makes clear sense. However, what is it that makes a rearward CG inherently less stable? Is it because the CG is closer to the Center of Pressure, so the effective moment arm is smaller?
Thanks
