wing-in-ground-effect craft

[‚wiŋ in ′grau̇nd i‚fekt ‚kraft]
(aerospace engineering)
A type of air-cushion vehicle that is similar in design to an aircraft and requires forward speed to provide lift; it flies very close to the surface, generally over water, to take advantage of the increased lift and reduction in induced drag that are characteristic of such flight. Also known as wing-in-surface-effect craft. Abbreviated WIG craft.
