着陆涉及更多的计划,因为可能有多个飞行员必须同时着陆。因此,已经建立了特定的流量模式。飞行员排在飞机场上方并降落在降落区一侧,该位置取决于风向,飞行员可能会因坐飞机而失去身高(如有必要)。从该位置开始,它们以矩形模式沿着飞行路径的腿到达着陆区:顺风腿进场。这允许在多个飞行员之间进行同步,并减少发生碰撞的风险,因为飞行员可以预测他周围的其他飞行员接下来将要做什么。
技术技巧
在进近下降过程中,在接触地面大约四米之前,可以施加一些瞬时制动,然后使用向前的摆动动量来获得速度,以更有效地展开并以**小的垂直速度接近地面。
在小风中,一些小跑很常见。在中等到中等的逆风中,着陆时可能没有前进速度,甚至在强风中甚至可能相对于地面后退。用风着陆会迫使飞行员向后退,这特别危险,因为它可能会翻滚并被拖拽。当机翼垂直于飞行员上方时,有可能降低风险放气。这涉及到每只手在槌/竖板交界处抓住前缘线(As),并通过深深的膝盖弯曲动作来施加飞行员的全部重量。在几乎每种情况下,机翼的前缘都会向前飞一点,然后“折”。然后,它可能会坍塌并下降到飞行员的上风处。在地面上,它将被飞行员的腿约束。

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.

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.
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.
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]
