An aft center of gravity increases flat spin risk. A flat spin happens when the center of gravity shifts too far aft (toward the tail), and the aircraft’s rotation becomes more horizontal. Some aircraft can enter flat spins even if their center of gravity is in the normal range.

The trigger can be any external force such as a wind gust or turbulence. Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. Doing so provides more lateral stability since the aircraft’s Center of Gravity (CG) lies below the wings.

However, the obstacles generate mechanical turbulence, making the air less stable. High-wing aircraft are particularly vulnerable due to their higher center of gravity. But remember, the crosswind you just battled is still hitting the aircraft’s wing and tail. Be prepared for gusts!

These control surfaces dictate the aircraft’s roll, and this allows it to bank smoothly through turns or even recover from turbulence. Most of the ailerons mass lies behind the hinge, making it tail-heavy. Tail-heavy ailerons droop downwards when they arent being pulled by the control system.
