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.

热飞行

托里·派恩斯滑翔伞在空中滑翔伞

当太阳温暖地面时，它将使某些功能比其他功能（例如岩石表面或大型建筑物）加热得更多，而这些功能会引发通过空气上升的热量。有时，这些可能只是空气的简单上升；通常，它们在风中向侧面吹，会从源头脱落，随后形成新的热量。

一旦飞行员找到了热量，他便开始绕圈飞行，试图将圆圈定位在热量最强的部分（“核心”）上，其中空气的上升最快。大多数飞行员使用可变高度计（“ vario”），通过嘟嘟声和/或视觉显示来指示爬升率，以帮助将热量插入磁芯中。

通常情况下，周围的热源周围有很强的水槽，当飞行员试图进入强热源时，也存在强烈的湍流，导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能，但是好的飞行员通常可以将热力一直贯穿到整个云层。

越野飞行

一旦掌握了使用热量来获得高度的技巧，飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后，飞行员会下滑到下一个可用热量。

潜在的热量可以通过通常会产生热量的陆地特征或积云来识别，这些积云标志着上升的一列温暖，潮湿的空气在到达露点并凝结成云时的顶部。

越野飞行员还需要熟悉航空法律，飞行法规，指示空域受限的航空地图等。

无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力，由飞行员通过操纵绳控制速度、方向等，实现无动力滑翔伞自由翱翔的。它起源于法国，于上世纪八十年代传入中国，截至目前，国内的持证滑翔伞飞行员刚刚过万人，是极富魅力与想象力并且很厉害的潮人运动。

      请记住，滑翔伞不是降落伞，降落伞是“可展式气动阻力器”，它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器，它能借助对流层中的热气流越飞越高，直到云底或者热气流消散的积云顶端。

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. 

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

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.

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]
