What is another word for ground effect?
Pronunciation: [ɡɹˈa͡ʊnd ɪfˈɛkt] (IPA) 
Ground effect refers to the aerodynamic phenomenon that occurs when an aircraft is close to the ground, leading to an increase in lift and a reduction in drag. There are several synonyms that can be used to describe ground effect, such as cushion of air, surface effect, or wing in ground effect (WIG). The term cushion of air refers to the air pressure that accumulates between the aircraft and the ground, creating a lift force. Surface effect is used to describe the effect of the ground on the airflow around the wings, resulting in a more efficient lift. Lastly, WIG refers to the specific category of aircraft that are designed to operate in ground effect.
