This can be very dangerous, because now the
forces on the line have to be controlled by the moving object itself, which is
almost impossible to do, unless stretchy rope and a pressure/tension meter
(dynamometer) is used. Static line towing with stretchy rope and a load cell as
a tension meter has been used in Poland, Ukraine, Russia, and other Eastern
European countries for over twenty years (under the name Malinka) with about
the same safety record as other forms of towing.[21] One more form of towing is
hand towing. This is where 1−3 people pull a paraglider using a tow rope of up
to 500 feet. The stronger the wind, the fewer people are needed for a
successful hand tow.[22] Tows up to 300 feet have been accomplished, allowing
the pilot to get into a lift band of a nearby ridge or row of buildings and
ridge-soar in the lift the same way as with a regular foot launch.[23]

SIV是模拟d'Incident en Vol(飞行中的事件模拟)的缩写,是提供有关如何应对不稳定和潜在危险情况(例如倒塌,满是失速和开裂)的课程。这些课程通常由经过特殊培训的讲师在大片水域上讲授,通常通过无线电指导学生。将指导学生如何诱发危险情况,从而学习一旦被诱发就如何避免和补救。向希望获得更高性能和更不稳定机翼的飞行员推荐该课程,这对于大多数飞行员而言都是自然而然的进步。在某些国家,SIV课程是初步飞行员培训的基本要求。万一出现无法挽回的机动导致水着陆的情况,通常会派出一艘救援船来收集飞行员。其他增加的安全功能可能包括浮力辅助装置或辅助备用降落伞。这些课程对于新手级别的飞行不是必不可少的。

Forward launch
In low winds, the wing is inflated with a
forward launch, where the pilot runs forward with the wing behind so that the
air pressure generated by the forward movement inflates the wing.
It is often easier, because the pilot only
has to run forward, but the pilot cannot see his wing until it is above him,
where he has to check it in a very short time for correct inflation and
untangled lines before the launch.
Reverse launch

Paraglider reverse launch, Mam Tor, England
In higher winds, a reverse launch is used,
with the pilot facing the wing to bring it up into a flying position, then
turning around under the wing and running to complete the launch.
Launching

Poland

India
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:
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.

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。 南通进口滑翔伞源头直供厂家
