Especially in the wings, icing on the control surface distorts aerodynamics. Raising the friction in the air and getting an invitation to the accident. Anti-icing and de-icing operations are performed on the ground to prevent icing on the plane. It is called "de-icing" and the anti-icing process is the process of clearing snow from the body and wings of the plane.
