Airfoil Center of Gravity Stability

Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Ice build-up on the airframe changes the airflow pattern around these airfoils. Additional Dangers of Ice Accumulation Icing also makes your aircraft heavier and can even change the position of the center of gravity.

They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. This is why the typical airfoil shape has a curved top and a flat bottom, especially in slower-speed general aviation aircraft. The aircraft pivots about its center of gravity. Wings do just that.

The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance. From the pilot’s seat it cruises near effortlessly and handles nimbly on land or water with a great combination of stability and modest control pressures.
