Ground Effect


Ground effect is the increased lift and decreased aerodynamic drag that an aircraft's wings generate when they are close to the ground or another large surface. This occurs because the ground blocks the airflow that normally occurs around the wingtips, creating a cushion of air that the wing can ride on. The result is that an aircraft can fly more efficiently and at lower speeds when it is in ground effect. This effect is particularly important for aircraft taking off or landing, as it allows them to use less runway and take off or land at lower speeds. However, it can also be dangerous if pilots are not aware of the changes in handling that can occur when transitioning from ground effect to normal flight.
