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).

滑翔伞驾驶员认证指导计划有几个关键组成部分。对初学者的初步培训通常从一定数量的地面学校开始，以讨论基础知识，包括基本的飞行理论以及滑翔伞的基本结构和操作。

然后，学生将学习如何在地面上控制滑翔机，练习起飞并控制机翼“高架”。接下来是低矮平缓的山丘，学生们可以在低空飞行，以习惯于在各种地形上操纵机翼。在没有丘陵的地区，可以使用特殊的绞车将滑翔机拖至低空。

随着技能的进步，学生们将进入更陡峭/更高的山丘（或更高的绞车拖曳），进行更长的飞行，并学习转动滑翔机，控制滑翔机的速度，然后继续进行360°转弯，点着陆，“大耳朵”

（用于增加滑翔伞的下降速度）和其他更先进的技术。通常通过无线电向学生提供培训说明，尤其是在首飞期间。

完整的滑翔伞教学计划的第三个关键要素是气象，航空法和一般飞行区礼节等关键领域的基本知识。

为了使准飞行员有机会确定他们是否愿意继续进行完整的飞行员培训计划，大多数学校都提供串联飞行，其中经验丰富的教练以准飞行员为乘客驾驶滑翔伞。学校通常会为飞行员的家人和朋友提供乘搭双人飞机的机会，有时还会在度假胜地出售乘搭双人飞机的乐趣。

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.

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line.

In 1952 Canadian Domina Jalbert patented a

governable gliding parachute with multi-cells and controls for lateral

glide.[2]

In 1954, Walter Neumark predicted (in an

article in Flight magazine) a time when a glider pilot would be "able to

launch himself by running over the edge of a cliff or down a slope ... whether

on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]

In 1961, the French engineer Pierre

Lemongine produced improved parachute designs that led to the Para-Commander.

The PC had cutouts at the rear and sides that enabled it to be towed into the

air and steered, leading to parasailing/parascending.

Domina Jalbert invented the Parafoil, which

had sectioned cells in an aerofoil shape; an open leading edge and a closed

trailing edge, inflated by passage through the air – the ram-air design. He

filed US Patent 3131894 on January 10, 1963.[4]
