What is the effect of a forward centre of gravity on stall speed?

A forward center of gravity (CG) has a significant impact on stall speed due to its influence on the aircraft's aerodynamics. When the CG is located forward, it affects the overall balance and stability of the aircraft. A forward CG generally leads to an increase in the stall speed for a few reasons.

First, with a forward CG, the aircraft requires a higher angle of attack to maintain level flight, which means that the wings must work harder to generate sufficient lift. As the angle of attack increases, there is a point at which the wings will stall. Therefore, a forward CG raises the angle of attack threshold at which stalling occurs, resulting in a higher stall speed.

Additionally, the increased stability associated with a forward CG can create a situation where the pilot has to exert more effort to manage the aircraft in a stall scenario. This change in aerodynamic behavior means that the aircraft may not only stall at a higher speed but also behave differently in terms of recovery dynamics.

In conclusion, a forward center of gravity increases stall speed due to the necessity for a greater angle of attack to maintain flight, leading to a higher stall speed being required to induce a stall.
