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.  黄浦区通用滑翔伞多少钱

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).

尽可能避免降落对机翼过大的风。在接近预定着陆点的过程中，这种潜在问题通常很明显，并且可能有机会扩大飞行范围，以找到更庇护的着陆区域。在每次着陆时，都希望机翼保持可飞行状态，并具有少量前向动量。这使放气更加可控。尽管中线（Bs）是垂直的，但是机翼快速顺风移动的机会要少得多。常见的放气提示来自后提升板管线（Cs或Ds）上的剧烈拉力。迅速旋转以迎面迎风，在后立管上保持压力，并在机翼掉落时朝机翼轻快迈进。通过实践，有可能实现精确的安全“无故障停车”。

对于着陆进场期间的强风，“拍打”机翼（制动器对称脉动）是**终的常见选择。它会降低机翼的升力性能。通过交替施加和释放制动器，下降速度大约每秒一次。该系统取决于飞行员对机翼的熟悉程度。机翼不得停转。应在飞行中，安全高度，良好条件下，并由观察员提供反馈的情况下，轻柔地进行安装。通常，制造商会根据批准重量范围内飞行员的平均身体比例来设定安全制动行程范围。应该以小幅增加对该设置进行更改，并在带有说明性标记的情况下显示这些变化，并进行试飞以确认所需的效果。缩短制动管路会产生使机翼变慢的问题。过度加长制动器会使机翼难以达到安全的着陆速度。

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.

在亚洲，日本、韩国、中国的中国台湾省等经济发达国家和地区的滑翔伞运动十分普及，爱好者达十多万人。20世纪80年代末，滑翔伞运动传入中国大陆并迅速发展，

现注册的航空俱乐部有50多个，正式会员1400多人，经常从事滑翔伞飞行者达数千人，在中国东北、长三角、珠三角长期有民间高手飞行，随着滑翔伞运动的逐渐普及，包括央视在内的很多电视媒体都对这一运动进行过专题报道。

滑翔伞通常主要由翼型伞衣、伞绳、背带系统和操纵系统四大部分组成。为便于滑翔伞的保管、携带与运输，每具滑翔伞还配有一只背式包装袋。

翼型伞衣，也称伞翼，是滑翔伞产生升力和承受载荷的主要部件。伞衣的形状、面积以及与气流相对运动的速度，对升力的产生有很大的影响。

翼型伞衣由上翼面、下翼面和沿翼展方向有规律分布的数十个成形翼肋构成。上下翼面与翼肋缝合，形成特定的伞翼形状。伞衣前缘按照翼肋的横向排列，构成一定尺寸的进气口。由于伞衣后缘是完全封闭的，所以上下翼面与各翼肋之间便形成了一个个用于储存空气的气室。 黄浦区通用滑翔伞多少钱
