Gliding flight is heavier-than-air flight without the use of thrust. It is employed by gliding animals and by aircraft such as gliders. The most common human application of gliding flight is in sport and recreation using aircraft designed for this purpose. However almost all powered aircraft are capable of gliding without engine power. As with sustained flight, gliding generally requires the application of an airfoil, such as the wings on aircraft or birds, or the gliding membrane on gliding possum. However, gliding can be achieved with a flat (uncambered) wing as with a simple paper plane, or even with card-throwing. The term volplaning has been used for this mode of flight.

Famous quotes containing the words gliding and/or flight:
“I stand on a bridge of one span
and see this calm act, this gathering up
of life, of spring water
and the Muse gliding ...”
—Denise Levertov (b. 1923)
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
