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]

滑翔伞锦标赛开幕式在大明山举行,来自国内46名前列滑翔伞运动员参加此次锦标赛。航空运动管理中心办公室主任叶正福、自然保护区管理局滕达初副局长参加开幕式并致辞。
叶正福表示,滑翔伞运动,作为航空运动的重要项目之一,在我区起步虽晚,但发展势头强劲。近几年,滑翔运动如雨后春笋般在八桂大地上发展壮大,处处开花。通过大家的不懈努力,现在,广西的滑翔伞运动产业已初具规模。此次锦标赛的举办,为发展我区滑翔运动,提高我区滑翔运动竞技水平提供难得的机遇。
滕达初表示,本次赛事的举办,将极大促进大明山“山地户外运动”旅游品牌的打造,为塑造广西大明山——“中国·东盟户外运动中心”品牌助力。作为户外运动会重要活动之一的滑翔伞锦标赛,也将打造广西大明山航空旅游的新名片,进一步提高广西航空体育运动旅游、体育旅游的竞争力,进一步提高大明山**度,将大明山户外运动聚集地形象推至全国乃至世界。

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。
The glide ratio of paragliders ranges from
9.3 for recreational wings to about 11.3 for modern competition models,[16]
reaching in some cases up to 13.[17] For comparison, a typical skydiving
parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for
recreational wings to about 16.5 for modern competition models. An idling
(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can
achieve a glide ratio of up to 72:1.
The speed range of paragliders is typically
20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.
Beginner wings will be in the lower part of this range, high-performance wings
in the upper part of the range.[note 2]
For storage and carrying, the wing is
usually folded into a stuffsack (bag), which can then be stowed in a large
backpack along with the harness. For pilots who may not want the added weight
or fuss of a backpack, some modern harnesses include the ability to turn the
harness inside out such that it becomes a backpack.
Reverse launches have a number of
advantages over a forward launch. It is more straightforward to inspect the
wing and check if the lines are free as it leaves the ground. In the presence
of wind, the pilot can be tugged toward the wing, and facing the wing makes it
easier to resist this force and safer in case the pilot slips (as opposed to
being dragged backwards). However, the movement pattern is more complex than
forward launch, and the pilot has to hold the brakes in a correct way and turn
to the correct side so he does not tangle the lines. These launches are
normally attempted with a reasonable wind speed, making the ground speed
required to pressurise the wing much lower.
The launch is initiated by the hands
raising the leading edge with the As. As it rises the wing is controlled more
by centring the feet than by use of the brakes or Cs. With mid level wings (EN
C and D) the wing may try to "overshoot" the pilot as it nears the
top. This is checked with Cs or brakes. The wing becomes increasingly sensitive
to the Cs and brakes as its internal air pressure rises.
