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。

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

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]

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. 

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.

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。
