WebGround effect, then, is due to the interference of the ground (or water) surface with the airflow patterns about the aircraft in flight. While the aerodynamic characteristics of the tail surfaces and the fuselage are altered by ground effect, the principal effects due to proximity of the ground are the changes in the aerodynamic characteristics of the wing. WebGround effect refers to the change in the airflow around the wing when it is very near the surface. At altitude, air can move freely up and over the wing and then down and …
