著陸涉及更多的計(jì)劃,因?yàn)榭赡苡卸鄠€(gè)飛行員必須同時(shí)著陸。因此,已經(jīng)建立了特定的流量模式。飛行員排在飛機(jī)場(chǎng)上方并降落在降落區(qū)一側(cè),該位置取決于風(fēng)向,飛行員可能會(huì)因坐飛機(jī)而失去身高(如有必要)。從該位置開(kāi)始,它們以矩形模式沿著飛行路徑的腿到達(dá)著陸區(qū):順風(fēng)腿進(jìn)場(chǎng)。這允許在多個(gè)飛行員之間進(jìn)行同步,并減少發(fā)生碰撞的風(fēng)險(xiǎn),因?yàn)轱w行員可以預(yù)測(cè)他周?chē)钠渌w行員接下來(lái)將要做什么。
技術(shù)技巧
在進(jìn)近下降過(guò)程中,在接觸地面大約四米之前,可以施加一些瞬時(shí)制動(dòng),然后使用向前的擺動(dòng)動(dòng)量來(lái)獲得速度,以更有效地展開(kāi)并以**小的垂直速度接近地面。
在小風(fēng)中,一些小跑很常見(jiàn)。在中等到中等的逆風(fēng)中,著陸時(shí)可能沒(méi)有前進(jìn)速度,甚至在強(qiáng)風(fēng)中甚至可能相對(duì)于地面后退。用風(fēng)著陸會(huì)迫使飛行員向后退,這特別危險(xiǎn),因?yàn)樗赡軙?huì)翻滾并被拖拽。當(dāng)機(jī)翼垂直于飛行員上方時(shí),有可能降低風(fēng)險(xiǎn)放氣。這涉及到每只手在槌/豎板交界處抓住前緣線(As),并通過(guò)深深的膝蓋彎曲動(dòng)作來(lái)施加飛行員的全部重量。在幾乎每種情況下,機(jī)翼的前緣都會(huì)向前飛一點(diǎn),然后“折”。然后,它可能會(huì)坍塌并下降到飛行員的上風(fēng)處。在地面上,它將被飛行員的腿約束。

飛行中的機(jī)翼放氣(崩潰)
由于機(jī)翼(機(jī)翼)的形狀是由進(jìn)入機(jī)翼并使之膨脹的運(yùn)動(dòng)空氣形成的,因此在湍流的空氣中,機(jī)翼的一部分或全部會(huì)收縮(塌陷)。被稱(chēng)為“主動(dòng)飛行”的飛行員技術(shù)將**降低通氣或坍塌的頻率和嚴(yán)重性。這種通縮通常無(wú)需飛行員干預(yù)即可恢復(fù)。如果發(fā)生嚴(yán)重的放氣,正確的飛行員輸入將加快從放氣中恢復(fù)的速度,但是錯(cuò)誤的飛行員輸入會(huì)減慢滑翔機(jī)返回正常飛行的速度,因此飛行員必須進(jìn)行正確的訓(xùn)練和練習(xí)以應(yīng)對(duì)放氣。
在極少數(shù)情況下,無(wú)法從通縮中恢復(fù)(或從諸如旋轉(zhuǎn)等其他威脅性狀況中)恢復(fù)過(guò)來(lái)的情況下,大多數(shù)飛行員會(huì)攜帶備用(救援,緊急情況)降落傘。但是,大多數(shù)飛行員從來(lái)沒(méi)有理由“扔”他們的儲(chǔ)備。如果機(jī)翼在低空發(fā)生放氣,即在起飛后不久或著陸前不久,機(jī)翼(滑翔傘)可能無(wú)法迅速恢復(fù)其正確的結(jié)構(gòu)以防止發(fā)生,飛行員通常沒(méi)有足夠的剩余高度來(lái)部署后備力量降落傘[**小降落高度大約為60 m(200 ft),但通常在穩(wěn)定期使用120-180 m(390-590 ft)的高度進(jìn)行典型部署]。備用降落傘的不同包裝方式會(huì)影響其部署時(shí)間。

Paragliders are unique among human-carrying
aircraft in being easily portable. The complete equipment packs into a rucksack
and can be carried easily on the pilot's back, in a car, or on public
transport.[14] In comparison with other air sports, this substantially
simplifies travel to a suitable takeoff spot, the selection of a landing place
and return travel.
Tandem paragliders, designed to carry the
pilot and one passenger, are larger but otherwise similar. They usually fly
faster with higher trim speeds, are more resistant to collapse, and have a
slightly higher sink rate compared to solo paragliders.
滑翔傘在“大耳朵”機(jī)動(dòng)
在不加速的情況下,正常飛行會(huì)拉動(dòng)外部A線,使翼尖向內(nèi)折疊,這將大大減小滑行角,而前進(jìn)速度*會(huì)小幅下降。隨著有效機(jī)翼面積的減小,機(jī)翼載荷增加,并且變得更加穩(wěn)定。但是,迎角增加了,飛行器更接近失速速度,但是可以通過(guò)應(yīng)用速度桿來(lái)改善,這也增加了下降速度。釋放管路時(shí),機(jī)翼會(huì)重新膨脹。如有必要,在制動(dòng)器上短暫抽氣有助于重新進(jìn)入正常飛行。與其他技術(shù)相比,機(jī)翼大了,機(jī)翼仍然向前滑動(dòng),這使飛行員可以離開(kāi)危險(xiǎn)區(qū)域。例如,如果飛行員必須抵抗斜坡上的上升氣流,這種方式甚至可以降落。
B線失速
在B線停轉(zhuǎn)中,從前緣/前端起的第二組立管(B線)**于其他立管被下拉,其中特定的線用于啟動(dòng)停轉(zhuǎn)。這在翼上產(chǎn)生翼展方向的折痕,從而使氣流與翼的上表面分離。它顯著降低了頂篷產(chǎn)生的升力,從而導(dǎo)致更高的下降率。這可能是費(fèi)力的動(dòng)作,因?yàn)楸仨殞⑦@些B線保持在該位置,并且機(jī)翼的張力會(huì)在這些線上施加向上的力。必須小心處理這些線的釋放,以免引起機(jī)翼向前飛快射擊,然后飛行員可能掉入其中。現(xiàn)在這已經(jīng)不那么流行了,因?yàn)樗跈C(jī)翼的內(nèi)部結(jié)構(gòu)上引起了高負(fù)荷。
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.

Land-based practice: Kiting
About that time, David Barish was
developing the "sail wing" (single-surface wing) for recovery of NASA
space capsules – "slope soaring was a way of testing out ... the Sail
Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he
went on to promote slope soaring as a summer activity for ski resorts.[6][7]
Author Walter Neumark wrote Operating
Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts
with a passion for tow-launching PCs and ram-air parachutes broke away from the
British Parachute Association to form the British Association of Parascending Clubs
(which later became the British Hang Gliding and Paragliding Association). In
1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.
Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the
first flight manual, The Paragliding Manual in 1985, coining the word
paragliding.
