Webground is approached. Increased blade efficiency while operating in ground effect is due to two separate and distinct phenomena. First and most important is the reduction of the velocity of the induced airflow. Since the ground interrupts the airflow under the helicopter, the entire flow is altered. This reduces downward velocity of the induced WebGround effect primarily affects the aerodynamic behavior of a conventional fixed-wing aircraft during landing. In order to understand what ground effect is and how it works, one must first understand the concept of trailing or tip vortices. A vortex is an energetic swirling mass of air or water like a tornado or whirlpool.

For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface. Reduced drag when in ground effect during takeoff can cause the aircraft to "float" while below the recommended climb speed.
