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).

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,

foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

 Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,

often climbing to altitudes of a few thousand metres.

像任何極限運動一樣，滑翔傘是一種潛在的危險活動。例如，在美國，2010年，一名滑翔傘飛行員死亡。這相當于5,000名飛行員中的一名。在1994-2010年間，每10,000名活躍的滑翔傘飛行員中平均有7人受到致命傷害，盡管近年來情況已有明顯改善。在法國（有超過25,000名注冊機員），2011年每10,000名飛行員中有2人受傷（這一比率并非2007-2011年的非典型），盡管每1,000名飛行員中約有6人受到嚴重傷害（超過2名飛行員，日間住院）。

通過培訓和風險管理可以**減少傷害的可能性。使用適當?shù)脑O備，例如為飛行員的身材和技能水平設計的機翼[28]，以及頭盔，備用降落傘[29]和緩沖式安全帶[30]，也可以很大程度地降低風險。飛行員的安全受到對現(xiàn)場條件（如空氣湍流（轉子），強熱，狂風和地面障礙物，如電力線）的了解的影響。勝任的教練對機翼控制和緊急演習進行足夠的飛行員培訓可以很大程度地減少。許多滑翔傘是飛行員錯誤和飛行條件差的結果。

Paragliders are unique among human-carrying

aircraft in being easily portable. The complete equipment packs into a rucksack

and can be carried easily on the pilot's back, in a car, or on public

transport.[14] In comparison with other air sports, this substantially

simplifies travel to a suitable takeoff spot, the selection of a landing place

and return travel.

Tandem paragliders, designed to carry the

pilot and one passenger, are larger but otherwise similar. They usually fly

faster with higher trim speeds, are more resistant to collapse, and have a

slightly higher sink rate compared to solo paragliders.

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.

Land-based practice: Kiting

About that time, David Barish was

developing the "sail wing" (single-surface wing) for recovery of NASA

space capsules – "slope soaring was a way of testing out ... the Sail

Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he

went on to promote slope soaring as a summer activity for ski resorts.[6][7]

Author Walter Neumark wrote Operating

Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts

with a passion for tow-launching PCs and ram-air parachutes broke away from the

British Parachute Association to form the British Association of Parascending Clubs

(which later became the British Hang Gliding and Paragliding Association). In

1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.

Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the

first flight manual, The Paragliding Manual in 1985, coining the word

paragliding.
