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.

在亞洲，日本、韓國、中國的中國臺灣省等經(jīng)濟發(fā)達國家和地區(qū)的滑翔傘運動十分普及，愛好者達十多萬人。20世紀80年代末，滑翔傘運動傳入中國大陸并迅速發(fā)展，
現(xiàn)注冊的航空俱樂部有50多個，正式會員1400多人，經(jīng)常從事滑翔傘飛行者達數(shù)千人，在中國東北、長三角、珠三角長期有民間高手飛行，隨著滑翔傘運動的逐漸普及，包括央視在內(nèi)的很多電視媒體都對這一運動進行過專題報道。
滑翔傘通常主要由翼型傘衣、傘繩、背帶系統(tǒng)和操縱系統(tǒng)四大部分組成。為便于滑翔傘的保管、攜帶與運輸，每具滑翔傘還配有一只背式包裝袋。
翼型傘衣，也稱傘翼，是滑翔傘產(chǎn)生升力和承受載荷的主要部件。傘衣的形狀、面積以及與氣流相對運動的速度，對升力的產(chǎn)生有很大的影響。
翼型傘衣由上翼面、下翼面和沿翼展方向有規(guī)律分布的數(shù)十個成形翼肋構(gòu)成。上下翼面與翼肋縫合，形成特定的傘翼形狀。傘衣前緣按照翼肋的橫向排列，構(gòu)成一定尺寸的進氣口。由于傘衣后緣是完全封閉的，所以上下翼面與各翼肋之間便形成了一個個用于儲存空氣的氣室。 青浦區(qū)**滑翔傘價格行情

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.
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]

世界經(jīng)濟的飛速發(fā)展以及科學技術(shù)的進步，讓運動、休閑活動出現(xiàn)，解放了人們傳統(tǒng)的體育鍛煉觀。就我國的市場經(jīng)濟發(fā)展情況來講，市場經(jīng)濟的轉(zhuǎn)型給我國運動、休閑事業(yè)的發(fā)展提供了良好的條件。隨著收入及生活水平的不斷提高，國人在運動、健身方面所加入的時間及財力均在逐年增長。國人參加運動或出于對某種運動項目的興趣，或者為健體強身。球類運動中，高爾夫球、網(wǎng)球也是較為大眾化的運動。劃船、沖浪、滑雪、釣魚、攀巖、騎車、跑步是國人運動、健身的主要方式。與這些運動有關(guān)的動力傘，滑翔傘，飛行，熱汽球均有較大的市場需求。運動休閑產(chǎn)業(yè)在我國的發(fā)展時間則較短，運動休閑用品在整個體育用品市場的占比不到千分之一，但隨著居民生活水平的提高，以及親近大自然休閑生活方式的興起，行業(yè)具備廣闊的發(fā)展空間，生產(chǎn)型公司發(fā)展前景非常廣闊。運動鞋服具有功能性與專業(yè)性的標簽， 近十年來隨著全球銷售之風愈演愈烈，消費者對于運動服飾的認識不斷刷新，從而形成廣義的“運動風”，對運動服飾的消費偏好加劇。徐州專業(yè)滑翔傘報價
