In small airplanes, why might recovery from spins become difficult?

In small airplanes, recovery from spins can become difficult when the center of gravity (CG) is too far rearward and the rotation occurs around the center of gravity. A rearward CG shifts the balance of the aircraft, making it more susceptible to entering a spin and complicating recovery efforts. This position changes the aerodynamic forces acting on the airplane during the spin, often resulting in a more pronounced and uncontrollable rotation.

When the aircraft is rotated around its CG, it can lead to an increase in adverse yaw and make it more challenging to apply the appropriate control inputs for recovery. The dynamics of the spin change depending on the location of the CG, and if it is too far back, the airplane may experience a deeper and more prolonged spin, complicating recovery maneuvers.

Understanding this relationship between the CG and the behavior of the aircraft during spins is essential for safe flight operations, especially in small airplanes. This is why the configuration of the aircraft and its loading affects spin recovery capabilities significantly.
