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.

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。

The next step in the launch is to bring the
wing into the lift zone. There are two techniques for accomplishing this
depending on wind conditions. In light wind this is usually done after turning
to the front, steering with the feet towards the low wing tip, and applying
light brakes in a natural sense to keep the wing horizontal. In stronger wind
conditions it is often found to be easier to remain facing downwind while
moving slowly and steadily backwards into the wind.
Knees bent to load the wing, foot
adjustments to remain central and minimum use of Cs or Brakes to keep the wing
horizontal. Pirouette when the feet are close to lifting. This option has two
distinct advantages. a) The pilot can see the wing centre marker (an aid to
centring the feet) and, if necessary, b) the pilot can move briskly towards the
wing to assist with an emergency deflation.
With either method it is essential to check
"traffic" across the launch face before committing to flight.
滑翔伞是飞行滑翔伞的娱乐和竞争性冒险运动:轻巧,自由飞行,脚踩滑翔机,没有刚性的基本结构[1]。
飞行员坐在悬挂在机翼下方的安全带中。
悬挂线,进入机翼前部通风孔的空气压力以及流过外部的空气的空气动力保持了机翼的形状。
尽管不使用发动机,滑翔伞飞行仍可持续数小时,飞行数百公里,尽管更常见的是飞行一到两个小时,飞行数十公里。
通过熟练地利用升力源,飞行员可以增加身高,通常会爬升到几千米的高度。
1954年,沃尔特·纽马克(Walter
Neumark)预测(在《飞行》杂志上的一篇文章),滑翔机飞行员“能够通过在悬崖边缘或斜坡上奔跑来发动自己……无论是在美国的攀岩假期中,
斯凯岛或阿尔卑斯山滑雪。”
1961年,法国工程师Pierre Lemongine制作了改进的降落伞设计,从而设计了Para-Commander。 PC的后部和侧面均设有切口,可将其拖入空中并进行操纵,从而实现滑翔伞运动。
多米娜·贾伯特(Domina Jalbert)发明了Parafoil,它具有呈翼型形状的切片细胞。 敞开式前缘和封闭式后缘,通过空气而膨胀-冲压空气设计。 他于1963年1月10日提交了美国专利3131894。
热飞行

当太阳温暖地面时,它将使某些功能比其他功能(例如岩石表面或大型建筑物)加热得更多,而这些功能会引发通过空气上升的热量。有时,这些可能只是空气的简单上升;通常,它们在风中向侧面吹,会从源头脱落,随后形成新的热量。
一旦飞行员找到了热量,他便开始绕圈飞行,试图将圆圈定位在热量**强的部分(“**”)上,其中空气的上升**快。大多数飞行员使用可变高度计(“ vario”),通过嘟嘟声和/或视觉显示来指示爬升率,以帮助将热量插入磁芯中。
通常情况下,周围的热源周围有很强的水槽,当飞行员试图进入强热源时,也存在强烈的湍流,导致机翼塌陷。良好的热力飞行是一项需要花费时间学习的技能,但是好的飞行员通常可以将热力一直贯穿到整个云层。
越野飞行
一旦掌握了使用热量来获得高度的技巧,飞行员就可以从一个热量滑到另一个热量来穿越国家。在热量中获得高度后,飞行员会下滑到下一个可用热量。
潜在的热量可以通过通常会产生热量的陆地特征或积云来识别,这些积云标志着上升的一列温暖,潮湿的空气在到达**并凝结成云时的顶部。
越野飞行员还需要熟悉航空法律,飞行法规,指示空域受限的航空地图等。

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]
