Why does moving the CG forward increase stalling airspeed?

When the center of gravity (CG) is moved forward, it affects the aircraft's balance and stability. One significant consequence of this adjustment is that it increases the wing loading, which is the aircraft's weight divided by the wing area. As wing loading increases, the aircraft requires a higher airspeed to generate enough lift needed to maintain controlled flight.

Specifically, with increased wing loading, the stall speed increases because the aircraft must achieve a higher angle of attack (AOA) to reach the critical lift required to sustain controlled flight before entering a stall. Thus, when an aircraft has a forward CG, the stall speed rises due to the need for more lift under increased wing loading, which contributes to increasing the stalling airspeed.

Additionally, stall behavior is also influenced by the distribution of weight and how it affects the aerodynamic performance of the wings, reinforcing the relationship between CG positioning and stalling characteristics.
