Reverse launches have a number of
advantages over a forward launch. It is more straightforward to inspect the
wing and check if the lines are free as it leaves the ground. In the presence
of wind, the pilot can be tugged toward the wing, and facing the wing makes it
easier to resist this force and safer in case the pilot slips (as opposed to
being dragged backwards). However, the movement pattern is more complex than
forward launch, and the pilot has to hold the brakes in a correct way and turn
to the correct side so he does not tangle the lines. These launches are
normally attempted with a reasonable wind speed, making the ground speed
required to pressurise the wing much lower.
The launch is initiated by the hands
raising the leading edge with the As. As it rises the wing is controlled more
by centring the feet than by use of the brakes or Cs. With mid level wings (EN
C and D) the wing may try to "overshoot" the pilot as it nears the
top. This is checked with Cs or brakes. The wing becomes increasingly sensitive
to the Cs and brakes as its internal air pressure rises.

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.

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。
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.
对于普通喜爱户外运动的人来说，经过滑翔伞教练的正规培训，要独自飞上蓝天其实很easy.客观的说，滑翔伞飞行是一项休闲航空运动，而非极限运动，只要身体无残疾、无精神疾病、无癫痫、无心脏病、等疾病的大众都可以参加.
在欧洲的四亿人中，注册的滑翔伞飞行员已经达到两百多万人。而在中国13亿人中，学习滑翔伞飞行的人少之又少，持有中航协颁发的滑翔伞飞行执照的飞行员，截止2019年5月才刚好一万人。中国与欧洲甚至韩国日本的滑翔伞运动水平差距如此之大，是因为这项运动传入中国大陆较晚，并且中国人的运动观念保守，有点谈“空”色变，只要是与飞行有关的运动，普通人都敬而远之不敢尝试。其实，滑翔伞运动在欧洲还被戏虐的称之为“老头乐”，七、八十岁仍然在飞滑翔伞的人大有人在，飞行对于他们，是一生不变的爱好。 苏州直销滑翔伞哪家强
