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.

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。 徐汇区滑翔伞多少钱
滑翔伞完整的设备打包成背包，可以轻松地放在飞行员的后背，汽车或公共交通工具上。[14]与其他航空运动相比，这**简化了到达合适起飞点的行程，着陆地点的选择和返程行程。
双人滑翔伞设计用来载飞行员和一名乘客，虽然较大，但在其他方面相似。与单独的滑翔伞相比，它们通常以更高的修剪速度飞行得更快，更不易塌陷，并且下沉率略高。
带线束的飞行员（浅蓝色），进行反向发射
飞行员可以轻松舒适地扣入安全带，该安全带可在站立和坐姿中提供支撑。大多数安全带在座椅下方和后方都有泡沫或安全气囊保护装置，以减少对失败的发射或着陆造成的影响。现代安全带的设计使其在坐姿或躺姿时都像躺椅一样舒适。许多背带甚至具有可调节的“腰部支撑”。备用降落伞通常也连接至滑翔伞背带。
线束也根据飞行员的需求而有所不同，因此设计范围很广，主要是：初学者的训练用安全带，双人旅客的Pax防护带（通常还兼用作训练用安全带），长距离越野飞行的XC线束， Pod线束，适用于基本至中级飞行员的全能线束，适用于专注于XC的中级至专业飞行员。杂技安全带是专为杂技飞行员设计的，儿童双人安全带现在也提供特殊的儿童防盗锁。
Harness
A pilot with harness (light blue),
performing a reverse launch
The pilot is loosely and comfortably
buckled into a harness, which offers support in both the standing and sitting
positions. Most harnesses have foam or airbag protectors underneath the seat
and behind the back to reduce the impact on failed launches or landings. Modern
harnesses are designed to be as comfortable as a lounge chair in the sitting or
reclining position. Many harnesses even have an adjustable "lumbar
support". A reserve parachute is also typically connected to a paragliding
harness.
Harnesses also vary according to the need
of the pilot, and thereby come in a range of designs, mostly: Training harness
for beginners, Pax harness for tandem passengers that often also doubles as a
training harness, XC Harness for long distance cross country flights, All round
harness for basic to intermediate pilots, Pod harness, which is for
intermediate to pro pilots that focus on XC. Acro harnesses are special designs
for acrobatic pilots, Kids tandem harnesses are also now available with special
child-proof locks.
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]

着陆涉及更多的计划，因为可能有多个飞行员必须同时着陆。因此，已经建立了特定的流量模式。飞行员排在飞机场上方并降落在降落区一侧，该位置取决于风向，飞行员可能会因坐飞机而失去身高（如有必要）。从该位置开始，它们以矩形模式沿着飞行路径的腿到达着陆区：顺风腿进场。这允许在多个飞行员之间进行同步，并减少发生碰撞的风险，因为飞行员可以预测他周围的其他飞行员接下来将要做什么。
技术技巧
在进近下降过程中，在接触地面大约四米之前，可以施加一些瞬时制动，然后使用向前的摆动动量来获得速度，以更有效地展开并以**小的垂直速度接近地面。
在小风中，一些小跑很常见。在中等到中等的逆风中，着陆时可能没有前进速度，甚至在强风中甚至可能相对于地面后退。用风着陆会迫使飞行员向后退，这特别危险，因为它可能会翻滚并被拖拽。当机翼垂直于飞行员上方时，有可能降低风险放气。这涉及到每只手在槌/竖板交界处抓住前缘线（As），并通过深深的膝盖弯曲动作来施加飞行员的全部重量。在几乎每种情况下，机翼的前缘都会向前飞一点，然后“折”。然后，它可能会坍塌并下降到飞行员的上风处。在地面上，它将被飞行员的腿约束。
