..wants to float above the ground. This is known as the ground effect. An aeroplane in normal flight high above the ground is subject to an undesirable force called induced drag. This force is the byproduct of lift production & is caused by the airflow below the wings spilling 2/

...downwash is restricted. So the formation of the wingtip vortices is also restricted. In ground effect the lift vector is not tilted back as much so total drag is less. This means that less thrust is required and to maintain the same airspeed. In ground effect the air ... 4/
