Gliding is a recreational activity and competitive air sport [1] in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne.
Examples of soaring flight by birds are the use of: Thermals and convergences by raptors such as vultures; Ridge lift by gulls near cliffs; Wave lift by migrating birds [33] Dynamic effects near the surface of the sea by albatrosses; For humans, soaring is the basis for three air sports: gliding, hang gliding and paragliding.
