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]

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.
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.
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。
