WebMay 21, 2024 · The ground effect can affect airplanes in several ways. As previously mentioned, it’s responsible for increasing an airplane’s lift and decreasing its drag during landings. Airplanes with fixed horizontal wings create air disturbances at their wingtips and behind their wings known as vortices. WebGround effect is caused by ground interference with airflow patterns around an aircraft when the aircraft is within one wingspan of the surface. If the approach airspeed is too fast, the aircraft will tend to float down the …
