As with all aircraft, launching and landing
are done into wind. The wing is placed into an airstream, either by running or
being pulled, or an existing wind. The wing moves up over the pilot into a
position in which it can carry the passenger. The pilot is then lifted from the
ground and, after a safety period, can sit down into his harness. Unlike
skydivers, paragliders, like hang gliders, do not "jump" at any time
during this process. There are two launching techniques used on higher
ground[20] and one assisted launch technique used in flatland areas:

SIV是模擬d'Incident en Vol(飛行中的事件模擬)的縮寫,是提供有關(guān)如何應(yīng)對(duì)不穩(wěn)定和潛在危險(xiǎn)情況(例如倒塌,滿是失速和開裂)的課程。這些課程通常由經(jīng)過特殊培訓(xùn)的講師在大片水域上講授,通常通過無(wú)線電指導(dǎo)學(xué)生。將指導(dǎo)學(xué)生如何誘發(fā)危險(xiǎn)情況,從而學(xué)習(xí)一旦被誘發(fā)就如何避免和補(bǔ)救。向希望獲得更高性能和更不穩(wěn)定機(jī)翼的飛行員推薦該課程,這對(duì)于大多數(shù)飛行員而言都是自然而然的進(jìn)步。在某些國(guó)家,SIV課程是初步飛行員培訓(xùn)的基本要求。萬(wàn)一出現(xiàn)無(wú)法挽回的機(jī)動(dòng)導(dǎo)致水著陸的情況,通常會(huì)派出一艘救援船來(lái)收集飛行員。其他增加的安全功能可能包括浮力輔助裝置或輔助備用降落傘。這些課程對(duì)于新手級(jí)別的飛行不是必不可少的。

像任何極限運(yùn)動(dòng)一樣,滑翔傘是一種潛在的危險(xiǎn)活動(dòng)。例如,在美國(guó),2010年,一名滑翔傘飛行員死亡。這相當(dāng)于5,000名飛行員中的一名。在1994-2010年間,每10,000名活躍的滑翔傘飛行員中平均有7人受到致命傷害,盡管近年來(lái)情況已有明顯改善。在法國(guó)(有超過25,000名注冊(cè)機(jī)員),2011年每10,000名飛行員中有2人受傷(這一比率并非2007-2011年的非典型),盡管每1,000名飛行員中約有6人受到嚴(yán)重傷害(超過2名飛行員,日間住院)。
通過培訓(xùn)和風(fēng)險(xiǎn)管理可以**減少傷害的可能性。使用適當(dāng)?shù)脑O(shè)備,例如為飛行員的身材和技能水平設(shè)計(jì)的機(jī)翼[28],以及頭盔,備用降落傘[29]和緩沖式安全帶[30],也可以很大程度地降低風(fēng)險(xiǎn)。飛行員的安全受到對(duì)現(xiàn)場(chǎng)條件(如空氣湍流(轉(zhuǎn)子),強(qiáng)熱,狂風(fēng)和地面障礙物,如電力線)的了解的影響。勝任的教練對(duì)機(jī)翼控制和緊急演習(xí)進(jìn)行足夠的飛行員培訓(xùn)可以很大程度地減少。許多滑翔傘是飛行員錯(cuò)誤和飛行條件差的結(jié)果。

作者Walter Neumark撰寫了《降落傘操作程序》,并于1973年與一群對(duì)拖曳PC和ram-air降落傘充滿熱情的愛好者脫離了英國(guó)降落傘協(xié)會(huì),成立了英國(guó)降落傘俱樂部協(xié)會(huì)(此協(xié)會(huì)后來(lái)成為英國(guó)的滑翔傘和滑翔傘協(xié)會(huì))。 1997年,紐馬克(Neumark)被英國(guó)皇家航空俱樂部(Royal Aero Club)授予獎(jiǎng)牌。作家Patrick Gilligan(加拿大)和Bertrand Dubuis(瑞士)于1985年撰寫了首本飛行手冊(cè)《滑翔傘手冊(cè)》,創(chuàng)造了滑翔傘一詞。
1978年6月,來(lái)自法國(guó)上薩瓦省Mieussy的三個(gè)朋友Jean-ClaudeBétemps,AndréBohn和GérardBosson將這些發(fā)展合并在一起。在跳傘者和發(fā)行人丹·波因特(Dan Poynter)在《降落傘手冊(cè)》雜志上發(fā)表的一篇有關(guān)坡度飛漲的文章的靈感啟發(fā)之后,[7]他們計(jì)算出,在合適的坡度上,可以通過順著坡道向“方形”的沖壓空氣降落傘充氣; Bétemps從Mieussy的Pointe du Pertuiset發(fā)射升空100 m。博恩跟隨他,滑到1000米以下山谷的足球場(chǎng)。
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

Paraglider reverse launch, Mam Tor, England
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.

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

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]
