https://flynhatrang.com/ https://flynhatrang.com/vi/ A paraglider wing is the main flying surface of a free-flying, foot-launched glider. Pilots sit in a harness suspended below the wing and are lifted by air flowing over its top surface, through vents in the wing's front section, and into chambers called ribs. Wing shape is maintained by tension in the suspension lines and pressure on the surface of the wing from air entering through the asymmetrical, swept-back leading edge. The wing is driven by the force of gravity and airflow, but is also responsive to pilot input and conditions. Wing performance is a key factor when choosing a glider. The speed and glide angle (or sink rate) of a paraglider determine how far it can go. A wing with good glide performance can fly long distances and reach high altitudes. Wings with good speed can cover ground more quickly, and some have the option of active control to allow them to turn and brake. The aspect ratio of a wing refers to the ratio of its span to its average chord. A wing with a higher aspect ratio is longer and narrower than one with a lower aspect ratio, which allows it to generate less induced drag for a given amount of lift. This makes it more efficient, but narrow wings are more susceptible to turbulence and require advanced skills to fly safely. occurs when the majority of the wing loses its aerodynamic shape, creating a dramatic loss of lift and potentially stalling in flight. It can be caused by severe turbulence, or by incorrect pilot input such as excessively slowing down in a thermal or gust. Full collapses are more common with high-aspect ratio wings, as their optimised performance profiles leave them with little margin for error. is the most dangerous wing condition, and can lead to a sudden loss of control. When the asymetric stall is triggered by a sudden increase in airspeed, the wing may fly into a steep turn and possibly enter a spin, which can be difficult or impossible to recover from. A large numb
