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.

A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIG), ground-effect craft, wingship, flarecraft or ekranoplan (), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the moving wing and the surface below.

Ground effect
Ground effect may refer to:
- Ground effect (aerodynamics), the increased lift and decreased aerodynamic drag of a wing close to a fixed surface
- Ground effect (cars), an effect that creates downforce, primarily in racing cars
- Ground effect vehicle, a vehicle which attains level flight near the surface of the Earth due to ground effect
- Ground effect train, an alternative to a magnetic levitation train, using ground effect in aircraft to prevent the vehicle from making contact with the ground

1. Officially this invention is a ‘wing in ground effect vehicle‘ – a hovercraft which is able to fly due to a set of unusual aerodynamics The hoverwing sets off like a normal–hovercraft but when it reaches top speed of 60mph, its wings can be extended and it takes flight.
