This paper describes the aerodynamic forces acting on the ski jumper during the landing phase as well as the free flight phase. The full size model was employed to measure the lift area, the drag area and the moment volume, which was mounted in a 3-meter low speed wind tunnel. The ground effect plate was set in the test section of the wind tunnel. The clearance between the plate and the center of mass of the body-ski combination was about 1 m. It was found that the difference between the lift area with the ground effect plate and that without the ground effect plate increased with the ski-opening angle, though difference of both lift areas was independent of the angle of attack. The difference of both drag areas was small. The flight distance was estimated about 146 m, which is 6 m longer by taking account of the ground effect.
