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.

像任何极限运动一样,滑翔伞是一种潜在的危险活动。例如,在美国,2010年,一名滑翔伞飞行员死亡。这相当于5,000名飞行员中的一名。在1994-2010年间,每10,000名活跃的滑翔伞飞行员中平均有7人受到致命伤害,尽管近年来情况已有明显改善。在法国(有超过25,000名注册机员),2011年每10,000名飞行员中有2人受伤(这一比率并非2007-2011年的非典型),尽管每1,000名飞行员中约有6人受到严重伤害(超过2名飞行员,日间住院)。
通过培训和风险管理可以**减少伤害的可能性。使用适当的设备,例如为飞行员的身材和技能水平设计的机翼[28],以及头盔,备用降落伞[29]和缓冲式安全带[30],也可以很大程度地降低风险。飞行员的安全受到对现场条件(如空气湍流(转子),强热,狂风和地面障碍物,如电力线)的了解的影响。胜任的教练对机翼控制和紧急演习进行足够的飞行员培训可以很大程度地减少。许多滑翔伞是飞行员错误和飞行条件差的结果。
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying,
foot-launched glider aircraft with no rigid primary structure.[1] The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.
Despite not using an engine, paragliderflights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height,
often climbing to altitudes of a few thousand metres.
In 1952 Canadian Domina Jalbert patented a
governable gliding parachute with multi-cells and controls for lateral
glide.[2]
In 1954, Walter Neumark predicted (in an
article in Flight magazine) a time when a glider pilot would be "able to
launch himself by running over the edge of a cliff or down a slope ... whether
on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]
In 1961, the French engineer Pierre
Lemongine produced improved parachute designs that led to the Para-Commander.
The PC had cutouts at the rear and sides that enabled it to be towed into the
air and steered, leading to parasailing/parascending.
Domina Jalbert invented the Parafoil, which
had sectioned cells in an aerofoil shape; an open leading edge and a closed
trailing edge, inflated by passage through the air – the ram-air design. He
filed US Patent 3131894 on January 10, 1963.[4]

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。
