Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

Wing

Cross section of a paraglider

Transverse cross section showing parts of a

paraglider:

1) upper surface

2) lower surface

3) rib

4) diagonal rib

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

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. 

大風降落的替代方法包括使用速度桿和大耳朵。速度桿可增加機翼的穿透力,并增加垂直下降率的少量增加。這使得在正式電路中更容易調節下降率。在極端情況下,建議您在離開線束后站在速度桿上,并保持在速度桿上,直到著陸和放氣為止。大耳朵通常在電路高度管理期間使用。垂直下降速度增加,并且可以利用該優點將滑翔機帶到適當的電路連接高度。大多數制造商都在高級機型中改變了大耳朵的操作技術。放開控制線后,C級滑翔機的大耳朵通常會保持折疊狀態。在那種情況下,機翼可以大耳朵部署,以合理的安全降落。在那些機翼類型中,通常需要兩到三個帶有制動器的對稱泵,再過一到兩秒鐘才能重新給葉尖充氣。在較低額定值的機翼中,“大耳朵”需要保持固定狀態以將耳朵固定。當它們固定在機翼中時,機翼往往會對側傾軸上的重量變化(由于有效面積減小)產生更好的響應。釋放管線后,它們會自動重新充氣。通常,這些機翼更適合拉入耳朵以擺脫多余高度的情況。然后應在基腳或著陸前幾秒鐘恢復全翼飛行。機翼熟悉度是應用這些控件的關鍵要素。飛行員應在中等條件下在安全區域,安全高度和有降落選項的情況下練習。


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.
