滑翔伞在“大耳朵”机动
在不加速的情况下,正常飞行会拉动外部A线,使翼尖向内折叠,这将大大减小滑行角,而前进速度*会小幅下降。随着有效机翼面积的减小,机翼载荷增加,并且变得更加稳定。但是,迎角增加了,飞行器更接近失速速度,但是可以通过应用速度杆来改善,这也增加了下降速度。释放管路时,机翼会重新膨胀。如有必要,在制动器上短暂抽气有助于重新进入正常飞行。与其他技术相比,机翼大了,机翼仍然向前滑动,这使飞行员可以离开危险区域。例如,如果飞行员必须抵抗斜坡上的上升气流,这种方式甚至可以降落。
B线失速
在B线停转中,从前缘/前端起的第二组立管(B线)**于其他立管被下拉,其中特定的线用于启动停转。这在翼上产生翼展方向的折痕,从而使气流与翼的上表面分离。它显着降低了顶篷产生的升力,从而导致更高的下降率。这可能是费力的动作,因为必须将这些B线保持在该位置,并且机翼的张力会在这些线上施加向上的力。必须小心处理这些线的释放,以免引起机翼向前飞快射击,然后飞行员可能掉入其中。现在这已经不那么流行了,因为它在机翼的内部结构上引起了高负荷。

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]

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.
The top of each line is attached to small
fabric loops sewn into the structure of the wing, which are generally arranged
in rows running span-wise (i.e., side to side). The row of lines nearest the
front are known as the A lines, the next row back the B lines, and so on.[14] A
typical wing will have A, B, C and D lines, but recently, there has been a
tendency to reduce the rows of lines to three, or even two (and experimentally
to one), to reduce drag.
Paraglider lines are usually made from
Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these
materials are immensely strong. For example, a single 0.66 mm-diameter line
(about the thinnest used) can have a breaking strength of 56 kg.[15]
Paraglider wings typically have an area of
20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and
weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,
instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).
