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.

每条线的顶部连接到缝在机翼结构中的小织物线圈上,这些织物线圈通常成行排列(即,左右)。**靠近前一行的行称为A线,下一行称为B线,依此类推。典型的机翼将具有A,B,C和D线,但是**近,有一种趋势是将行的行数减少到三行,甚至两行(并从实验上减少到一行),以减少阻力。
滑翔伞线通常由迪尼玛/光谱或凯夫拉尔/芳纶制成。尽管它们看起来很苗条,但这些材料非常坚固。例如,一条直径为0.66毫的线(大约**细)可以具有56千克的断裂强度。
滑翔伞的滑翔率范围从休闲机翼的9.3到现代竞赛模型的约11.3,在某些情况下高达13。为了进行比较,典型的跳伞降落伞将实现约3:1的滑行。悬挂式滑翔机的范围从休闲机翼的9.5到现代竞赛机型的约16.5。空转(滑行)的塞斯纳152轻型飞机将达到9:1。一些滑翔机可以实现高达72:1的滑行比。
滑翔伞的速度范围通常为每小时20-75公里(12-47英里/小时),从失速速度到比较大速度。初学者机翼将位于该范围的下部,高性能机翼将位于该范围的上部。
为了存放和携带,机翼通常被折叠成一个行李袋,然后可以与安全带一起存放在一个大背包中。对于可能不希望增加背包重量或烦恼的飞行员,一些现代安全带具有将安全带内翻的功能,从而使其成为背包。

大风降落的替代方法包括使用速度杆和大耳朵。速度杆可增加机翼的穿透力,并增加垂直下降率的少量增加。这使得在正式电路中更容易调节下降率。在极端情况下,建议您在离开线束后站在速度杆上,并保持在速度杆上,直到着陆和放气为止。大耳朵通常在电路高度管理期间使用。垂直下降速度增加,并且可以利用该优点将滑翔机带到适当的电路连接高度。大多数制造商都在高级机型中改变了大耳朵的操作技术。放开控制线后,C级滑翔机的大耳朵通常会保持折叠状态。在那种情况下,机翼可以大耳朵部署,以合理的安全降落。在那些机翼类型中,通常需要两到三个带有制动器的对称泵,再过一到两秒钟才能重新给叶尖充气。在较低额定值的机翼中,“大耳朵”需要保持固定状态以将耳朵固定。当它们固定在机翼中时,机翼往往会对侧倾轴上的重量变化(由于有效面积减小)产生更好的响应。释放管线后,它们会自动重新充气。通常,这些机翼更适合拉入耳朵以摆脱多余高度的情况。然后应在基脚或着陆前几秒钟恢复全翼飞行。机翼熟悉度是应用这些控件的关键要素。飞行员应在中等条件下在安全区域,安全高度和有降落选项的情况下练习。

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.
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.

Launching

As with all aircraft, launching and landing
are done into wind. The wing is placed into an airstream, either by running or
being pulled, or an existing wind. The wing moves up over the pilot into a
position in which it can carry the passenger. The pilot is then lifted from the
ground and, after a safety period, can sit down into his harness. Unlike
skydivers, paragliders, like hang gliders, do not "jump" at any time
during this process. There are two launching techniques used on higher
ground[20] and one assisted launch technique used in flatland areas:
