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.  嘉定区直销滑翔伞便宜

无动力滑翔伞是借助伞翼在空中相对空气的运动产生的升力，由飞行员通过操纵绳控制速度、方向等，实现无动力滑翔伞自由翱翔的。它起源于法国，于上世纪八十年代传入中国，截至目前，国内的持证滑翔伞飞行员刚刚过万人，是极富魅力与想象力并且很厉害的潮人运动。

      请记住，滑翔伞不是降落伞，降落伞是“可展式气动阻力器”，它能让人或物体从空中以较小的匀速下降。而滑翔伞是人类目前创造出的简易的飞行器，它能借助对流层中的热气流越飞越高，直到云底或者热气流消散的积云顶端。 青浦区销售滑翔伞价格如何计算

大约在那个时候，大卫·巴里什（David Barish）正在开发用于恢复NASA太空舱的“帆翼”（单面翼）-“高耸的斜坡是一种测试……帆翼的方法。” 在对Hunter进行测试之后1965年9月，他在纽约的山上继续推广滑雪胜地的夏季活动[6] [7]。

作者Walter Neumark撰写了《降落伞操作程序》，并于1973年与一群对拖曳PC和ram-air降落伞充满热情的爱好者脱离了英国降落伞协会，成立了英国降落伞俱乐部协会（此协会后来成为英国的滑翔伞和滑翔伞协会）。 1997年，纽马克（Neumark）被英国皇家航空俱乐部（Royal Aero Club）授予奖牌。作家Patrick Gilligan（加拿大）和Bertrand Dubuis（瑞士）于1985年撰写了首本飞行手册《滑翔伞手册》，创造了滑翔伞一词。

1978年6月，来自法国上萨瓦省Mieussy的三个朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson将这些发展合并在一起。在跳伞者和发行人丹·波因特（Dan Poynter）在《降落伞手册》杂志上发表的一篇有关坡度飞涨的文章的灵感启发之后，[7]他们计算出，在合适的坡度上，可以通过顺着坡道向“方形”的冲压空气降落伞充气； Bétemps从Mieussy的Pointe du Pertuiset发射升空100 m。博恩跟随他，滑到1000米以下山谷的足球场。

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。

In

flatter countryside, pilots can also be launched with a tow. Once at full

height (towing can launch pilots up to 3000 feet altitude), the pilot pulls a

release cord, and the towline falls away. This requires separate training, as

flying on a winch has quite different characteristics from free flying. There

are two major ways to tow: pay-in and pay-out towing. Pay-in towing involves a

stationary winch that winds in the towline and thereby pulls the pilot in the

air. The distance between winch and pilot at the start is around 500 metres or

more. Pay-out towing involves a moving object, like a car or a boat, that pays

out line slower than the speed of the object, thereby pulling the pilot up in

the air. In both cases, it is very important to have a gauge indicating line

tension to avoid pulling the pilot out of the air. Another form of towing is

"static line" towing. This involves a moving object, like a car or a

boat, attached to a paraglider or hang glider with a fixed-length line. 徐州口碑好滑翔伞价格合理

Harness

The pilot is loosely and comfortably

buckled into a harness, which offers support in both the standing and sitting

positions. Most harnesses have foam or airbag protectors underneath the seat

and behind the back to reduce the impact on failed launches or landings. Modern

harnesses are designed to be as comfortable as a lounge chair in the sitting or

reclining position. Many harnesses even have an adjustable "lumbar

support". A reserve parachute is also typically connected to a paragliding

harness.

Harnesses also vary according to the need

of the pilot, and thereby come in a range of designs, mostly: Training harness

for beginners, Pax harness for tandem passengers that often also doubles as a

training harness, XC Harness for long distance cross country flights, All round

harness for basic to intermediate pilots, Pod harness, which is for

intermediate to pro pilots that focus on XC. Acro harnesses are special designs

for acrobatic pilots, Kids tandem harnesses are also now available with special

child-proof locks.
