飞行中的机翼放气（崩溃）
由于机翼（机翼）的形状是由进入机翼并使之膨胀的运动空气形成的，因此在湍流的空气中，机翼的一部分或全部会收缩（塌陷）。被称为“主动飞行”的飞行员技术将**降低通气或坍塌的频率和严重性。这种通缩通常无需飞行员干预即可恢复。如果发生严重的放气，正确的飞行员输入将加快从放气中恢复的速度，但是错误的飞行员输入会减慢滑翔机返回正常飞行的速度，因此飞行员必须进行正确的训练和练习以应对放气。
在极少数情况下，无法从通缩中恢复（或从诸如旋转等其他威胁性状况中）恢复过来的情况下，大多数飞行员会携带备用（救援，紧急情况）降落伞。但是，大多数飞行员从来没有理由“扔”他们的储备。如果机翼在低空发生放气，即在起飞后不久或着陆前不久，机翼（滑翔伞）可能无法迅速恢复其正确的结构以防止发生，飞行员通常没有足够的剩余高度来部署后备力量降落伞[**小降落高度大约为60 m（200 ft），但通常在稳定期使用120-180 m（390-590 ft）的高度进行典型部署]。备用降落伞的不同包装方式会影响其部署时间。

滑翔伞是一批热爱跳伞、滑翔翼的飞行人员发明的一种飞行运动，目前在欧美和日本等国非常流行，在中国台湾也掀起了一股旋风。滑翔伞与传统的降落伞不同，它是一种飞行器。很久以前，人类为寻找一双翅膀作过无数次的思考和探索。在古老的中国大地上，留下了像“驾车遨游太空”、“嫦娥奔月”等许多关于人类尝试飞行的美好传说。当今，滑翔伞的诞生，为人类插上了飞翔的翅膀。人们自由地翱翔于天空，享受着“脱离”地球引力的宁静与美妙.滑翔伞起源于20世纪70年代初的欧洲，当时，一些登山者从山上乘降落伞滑翔而**验到了一种美好的感觉和乐趣，从而创立了一个新兴的航空体育项目。**初的滑翔伞是借鉴于飞机跳伞使用的翼型方伞，它主要以下降为主，下降速度快，安全性能好。通过二十多年的发展和演变。现在的滑翔伞**长飞行17小时，**远飞行距离超过300公里，它体现了一种人与自然的交流，备受崇尚自然者的喜爱。青浦区销售滑翔伞价格如何计算
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.
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]
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.

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.
