What makes a plane more stable?

A plane's stability is influenced by its design features, such as the placement of the center of gravity, wing configuration, and tail design. A lower center of gravity enhances stability by reducing the tendency to tip over. Additionally, larger wings and horizontal stabilizers can improve aerodynamic stability, allowing the aircraft to return to a level flight position after disturbances. Overall, a well-balanced and aerodynamically efficient design contributes significantly to a plane's stability.
