The top of each line is attached to small
fabric loops sewn into the structure of the wing, which are generally arranged
in rows running span-wise (i.e., side to side). The row of lines nearest the
front are known as the A lines, the next row back the B lines, and so on.[14] A
typical wing will have A, B, C and D lines, but recently, there has been a
tendency to reduce the rows of lines to three, or even two (and experimentally
to one), to reduce drag.
Paraglider lines are usually made from
Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these
materials are immensely strong. For example, a single 0.66 mm-diameter line
(about the thinnest used) can have a breaking strength of 56 kg.[15]
Paraglider wings typically have an area of
20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and
weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,
instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).

These developments were combined in June
1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from
Mieussy, Haute-Savoie, France. After inspiration from an article on slope
soaring in the Parachute Manual magazine by parachutist and publisher Dan
Poynter,[7] they calculated that on a suitable slope, a "square"
ram-air parachute could be inflated by running down the slope; Bétemps launched
from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided
down to the football pitch in the valley 1000 metres below.[8]
"Parapente" (pente being French for "slope") was born.
From the 1980s, equipment has continued to
improve, and the number of paragliding pilots and established sites has
continued to increase. The first (unofficial) Paragliding World Championship
was held in Verbier, Switzerland, in 1987,[9] though the first officially
sanctioned FAI World Paragliding Championship was held in Kössen, Austria, in
1989.[10]

无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力，由飞行员通过操纵绳控制速度、方向等，实现无动力滑翔伞自由翱翔的。它起源于法国，于上世纪八十年代传入中国，截至目前，国内的持证滑翔伞飞行员刚刚过万人，是极富魅力与想象力并且很厉害的潮人运动。
请记住，滑翔伞不是降落伞，降落伞是“可展式气动阻力器”，它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器，它能借助对流层中的热气流越飞越高，直到云底或者热气流消散的积云顶端。
SIV是模拟d'Incident en Vol（飞行中的事件模拟）的缩写，是提供有关如何应对不稳定和潜在危险情况（例如倒塌，满是失速和开裂）的课程。这些课程通常由经过特殊培训的讲师在大片水域上讲授，通常通过无线电指导学生。将指导学生如何诱发危险情况，从而学习一旦被诱发就如何避免和补救。向希望获得更高性能和更不稳定机翼的飞行员推荐该课程，这对于大多数飞行员而言都是自然而然的进步。在某些国家，SIV课程是初步飞行员培训的基本要求。万一出现无法挽回的机动导致水着陆的情况，通常会派出一艘救援船来收集飞行员。其他增加的安全功能可能包括浮力辅助装置或辅助备用降落伞。这些课程对于新手级别的飞行不是必不可少的。
对于普通喜爱户外运动的人来说，经过滑翔伞教练的正规培训，要独自飞上蓝天其实很easy.客观的说，滑翔伞飞行是一项休闲航空运动，而非极限运动，只要身体无残疾、无精神疾病、无癫痫、无心脏病、等疾病的大众都可以参加.
在欧洲的四亿人中，注册的滑翔伞飞行员已经达到两百多万人。而在中国13亿人中，学习滑翔伞飞行的人少之又少，持有中航协颁发的滑翔伞飞行执照的飞行员，截止2019年5月才刚好一万人。中国与欧洲甚至韩国日本的滑翔伞运动水平差距如此之大，是因为这项运动传入中国大陆较晚，并且中国人的运动观念保守，有点谈“空”色变，只要是与飞行有关的运动，普通人都敬而远之不敢尝试。其实，滑翔伞运动在欧洲还被戏虐的称之为“老头乐”，七、八十岁仍然在飞滑翔伞的人大有人在，飞行对于他们，是一生不变的爱好。 南通正规滑翔伞多少钱

The glide ratio of paragliders ranges from
9.3 for recreational wings to about 11.3 for modern competition models,[16]
reaching in some cases up to 13.[17] For comparison, a typical skydiving
parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for
recreational wings to about 16.5 for modern competition models. An idling
(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can
achieve a glide ratio of up to 72:1.
The speed range of paragliders is typically
20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.
Beginner wings will be in the lower part of this range, high-performance wings
in the upper part of the range.[note 2]
For storage and carrying, the wing is
usually folded into a stuffsack (bag), which can then be stowed in a large
backpack along with the harness. For pilots who may not want the added weight
or fuss of a backpack, some modern harnesses include the ability to turn the
harness inside out such that it becomes a backpack.
