A paper airplane is capable of proper flight only if it is stable both statically and dynamically.
A stable airplane in flight is one which, when disturbed, will automatically bring itself back to it is original course.
A stable airplane must, therefore, have longitudinal, directional and lateral stability.
Longitudinal stability refers to an airplane pitching it is nose up or down.
Directional stability refers to an airplane yawing to the right or left and lateral stability refers to an airplane rolling clock-wise or anti-clockwise.
Careful design and selection of the airplane is fuselage, wings, fins, vertical and horizontal stabilizers, as well as the location of the center of gravity, are necessary to ensure stability.
Without getting into the complex theory regarding airplane stability, the following are generally true of a paper airplane, and may be useful to help you understand and make a better, or a more stable, paper airplane on your own: • Moving the center of gravity towards the front of the airplane will enhance longitudinal stability.
The same is also true for having a smaller wing area towards the front, and a larger wing area towards the rear of the airplane.
