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).

In some modern paragliders (from the 1990s
onwards), especially higher-performance wings, some of the cells of the leading
edge are closed to form a cleaner aerodynamic profile. Holes in the internal
ribs allow a free flow of air from the open cells to these closed cells to
inflate them, and also to the wingtips, which are also closed.[13]
The pilot is supported underneath the wing
by a network of suspension lines. These start with two sets of risers made of
short (40 cm) lengths of strong webbing. Each set is attached to the harness by
a carabiner, one on each side of the pilot, and each riser of a set is generally
attached to lines from only one row of its side of wing. At the end of each
riser of the set, there is a small delta maillon with a number (2 – 5) of lines
attached, forming a fan. These are typically 4 – 5 metres long, with the end
attached to 2 ? 4 further lines of around 2 m, which are again joined to a
group of smaller, thinner lines. In some cases this is repeated for a fourth
cascade.

Europe has seen the greatest growth in
paragliding, with France alone registering in 2011 over 25,000 active pilots.

The paraglider wing or canopy is usually
what is known in engineering as a "ram-air airfoil". Such wings
comprise two layers of fabric that are connected to internal supporting
material in such a way as to form a row of cells. By leaving most of the cells
open only at the leading edge, incoming air keeps the wing inflated, thus
maintaining its shape. When inflated, the wing's cross-section has the typical
teardrop aerofoil shape. Modern paraglider wings are made of high-performance
non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]
對于普通喜愛戶外運動的人來說，經(jīng)過滑翔傘教練的正規(guī)培訓(xùn)，要獨自飛上藍天其實很easy.客觀的說，滑翔傘飛行是一項休閑航空運動，而非極限運動，只要身體無殘疾、無精神疾病、無癲癇、無心臟病、等疾病的大眾都可以參加.
在歐洲的四億人中，注冊的滑翔傘飛行員已經(jīng)達到兩百多萬人。而在中國13億人中，學(xué)習(xí)滑翔傘飛行的人少之又少，持有中航協(xié)頒發(fā)的滑翔傘飛行執(zhí)照的飛行員，截止2019年5月才剛好一萬人。中國與歐洲甚至韓國日本的滑翔傘運動水平差距如此之大，是因為這項運動傳入中國大陸較晚，并且中國人的運動觀念保守，有點談“空”色變，只要是與飛行有關(guān)的運動，普通人都敬而遠之不敢嘗試。其實，滑翔傘運動在歐洲還被戲虐的稱之為“老頭樂”，七、八十歲仍然在飛滑翔傘的人大有人在，飛行對于他們，是一生不變的愛好。

大約在那個時候，大衛(wèi)·巴里什（David Barish）正在開發(fā)用于恢復(fù)NASA太空艙的“帆翼”（單面翼）-“高聳的斜坡是一種測試……帆翼的方法。” 在對Hunter進行測試之后1965年9月，他在紐約的山上繼續(xù)推廣滑雪勝地的夏季活動[6] [7]。
作者Walter Neumark撰寫了《降落傘操作程序》，并于1973年與一群對拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國降落傘協(xié)會，成立了英國降落傘俱樂部協(xié)會（此協(xié)會后來成為英國的滑翔傘和滑翔傘協(xié)會）。 1997年，紐馬克（Neumark）被英國皇家航空俱樂部（Royal Aero Club）授予獎牌。作家Patrick Gilligan（加拿大）和Bertrand Dubuis（瑞士）于1985年撰寫了首本飛行手冊《滑翔傘手冊》，創(chuàng)造了滑翔傘一詞。
1978年6月，來自法國上薩瓦省Mieussy的三個朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson將這些發(fā)展合并在一起。在跳傘者和發(fā)行人丹·波因特（Dan Poynter）在《降落傘手冊》雜志上發(fā)表的一篇有關(guān)坡度飛漲的文章的靈感啟發(fā)之后，[7]他們計算出，在合適的坡度上，可以通過順著坡道向“方形”的沖壓空氣降落傘充氣； Bétemps從Mieussy的Pointe du Pertuiset發(fā)射升空100 m。博恩跟隨他，滑到1000米以下山谷的足球場。
