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.

Europe has seen the greatest growth in
paragliding, with France alone registering in 2011 over 25,000 active pilots.

Cross section of a paraglider
Transverse cross section showing parts of a
paraglider:
1) upper surface
2) lower surface
3) rib
4) diagonal rib
5) upper line cascade
6) middle line cascade
7) lower line cascade
8) risers
The paraglider wing or canopy is usually
what is known in engineering as a "ram-air airfoil". Such wings
comprise two layers of fabric that are connected to internal supporting
material in such a way as to form a row of cells. By leaving most of the cells
open only at the leading edge, incoming air keeps the wing inflated, thus
maintaining its shape. When inflated, the wing's cross-section has the typical
teardrop aerofoil shape. Modern paraglider wings are made of high-performance
non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

像任何极限运动一样，滑翔伞是一种潜在的危险活动。例如，在美国，2010年，一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间，每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害，尽管近年来情况已有明显改善。在法国（有超过25,000名注册机员），2011年每10,000名飞行员中有2人受伤（这一比率并非2007-2011年的非典型），尽管每1,000名飞行员中约有6人受到严重伤害（超过2名飞行员，日间住院）。
通过培训和风险管理可以**减少伤害的可能性。使用适当的设备，例如为飞行员的身材和技能水平设计的机翼[28]，以及头盔，备用降落伞[29]和缓冲式安全带[30]，也可以很大程度地降低风险。飞行员的安全受到对现场条件（如空气湍流（转子），强热，狂风和地面障碍物，如电力线）的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。
滑翔伞运动是一项崇尚自由、充满阳光的休闲娱乐运动，它能给人带来一种象鸟儿一样自由自在、驭风而行的感受。让山间清新的风，轻拂过我们的脸庞，飞翔在高山之上，蓝天之中，呼吸着清纯的空气，远离生活的烦恼和都市的喧嚣。让久已抑郁的心灵得到一次彻底的解放，俯瞰大地，林海莽莽，峰峦叠翠，尽收眼底。
滑翔伞运动也是一项包容性很强的飞行运动，从七八岁的孩子到六七十岁的老人都可以借助滑翔伞自由翱翔，也给喜欢挑战极限、超越自我的人带来了无限的**!所以滑翔伞运动广受喜爱。
一般的滑翔伞，它是慢速、轻柔、安静的，优雅地漂浮于空中，在温暖的阳光下、在和煦的风中飞行，它既是一项运动，也是一种游戏。如今，滑翔伞项目已被纳入2018年印尼亚运会项目，所以今年我们还可以通过电视一睹滑翔伞运动的风采以及滑翔伞飞行员比赛的精彩瞬间。
Radio
Radio communications are used in training,
to communicate with other pilots, and to report where and when they intend to
land. These radios normally operate on a range of frequencies in different
countries—some authorised,[18][19] some illegal but tolerated locally. Some
local authorities (e.g., flight clubs) offer periodic automated weather updates
on these frequencies. In rare cases, pilots use radios to talk to airport
control towers or air traffic controllers. Many pilots carry a cell phone so
they can call for pickup should they land away from their intended point of
destination.
GPS
GPS (global positioning system) is a
necessary accessory when flying competitions, where it has to be demonstrated
that way-points have been correctly passed. The recorded GPS track of a flight
can be used to analyze flying technique or can be shared with other pilots. GPS
is also used to determine drift due to the prevailing wind when flying at
altitude, providing position information to allow restricted airspace to be
avoided and identifying one's location for retrieval teams after landing out in
unfamiliar territory. 徐汇区滑翔伞报价

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]
