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.  虹口區(qū)**滑翔傘多少錢(qián)

滑翔傘在“大耳朵”機(jī)動(dòng)

在不加速的情況下，正常飛行會(huì)拉動(dòng)外部A線，使翼尖向內(nèi)折疊，這將大大減小滑行角，而前進(jìn)速度*會(huì)小幅下降。隨著有效機(jī)翼面積的減小，機(jī)翼載荷增加，并且變得更加穩(wěn)定。但是，迎角增加了，飛行器更接近失速速度，但是可以通過(guò)應(yīng)用速度桿來(lái)改善，這也增加了下降速度。釋放管路時(shí)，機(jī)翼會(huì)重新膨脹。如有必要，在制動(dòng)器上短暫抽氣有助于重新進(jìn)入正常飛行。與其他技術(shù)相比，機(jī)翼大了，機(jī)翼仍然向前滑動(dòng)，這使飛行員可以離開(kāi)危險(xiǎn)區(qū)域。例如，如果飛行員必須抵抗斜坡上的上升氣流，這種方式甚至可以降落。

B線失速

在B線停轉(zhuǎn)中，從前緣/前端起的第二組立管（B線）**于其他立管被下拉，其中特定的線用于啟動(dòng)停轉(zhuǎn)。這在翼上產(chǎn)生翼展方向的折痕，從而使氣流與翼的上表面分離。它顯著降低了頂篷產(chǎn)生的升力，從而導(dǎo)致更高的下降率。這可能是費(fèi)力的動(dòng)作，因?yàn)楸仨殞⑦@些B線保持在該位置，并且機(jī)翼的張力會(huì)在這些線上施加向上的力。必須小心處理這些線的釋放，以免引起機(jī)翼向前飛快射擊，然后飛行員可能掉入其中?，F(xiàn)在這已經(jīng)不那么流行了，因?yàn)樗跈C(jī)翼的內(nèi)部結(jié)構(gòu)上引起了高負(fù)荷。

作者Walter Neumark撰寫(xiě)了《降落傘操作程序》，并于1973年與一群對(duì)拖曳PC和ram-air降落傘充滿熱情的愛(ài)好者脫離了英國(guó)降落傘協(xié)會(huì)，成立了英國(guó)降落傘俱樂(lè)部協(xié)會(huì)（此協(xié)會(huì)后來(lái)成為英國(guó)的滑翔傘和滑翔傘協(xié)會(huì)）。 1997年，紐馬克（Neumark）被英國(guó)皇家航空俱樂(lè)部（Royal Aero Club）授予獎(jiǎng)牌。作家Patrick Gilligan（加拿大）和Bertrand Dubuis（瑞士）于1985年撰寫(xiě)了首本飛行手冊(cè)《滑翔傘手冊(cè)》，創(chuàng)造了滑翔傘一詞。

1978年6月，來(lái)自法國(guó)上薩瓦省Mieussy的三個(gè)朋友Jean-ClaudeBétemps，AndréBohn和GérardBosson將這些發(fā)展合并在一起。在跳傘者和發(fā)行人丹·波因特（Dan Poynter）在《降落傘手冊(cè)》雜志上發(fā)表的一篇有關(guān)坡度飛漲的文章的靈感啟發(fā)之后，[7]他們計(jì)算出，在合適的坡度上，可以通過(guò)順著坡道向“方形”的沖壓空氣降落傘充氣； Bétemps從Mieussy的Pointe du Pertuiset發(fā)射升空100 m。博恩跟隨他，滑到1000米以下山谷的足球場(chǎng)。

The glide ratio of paragliders ranges from

9.3 for recreational wings to about 11.3 for modern competition models,[16]

reaching in some cases up to 13.[17] For comparison, a typical skydiving

parachute will achieve about 3:1 glide. A hang glider ranges from 9.5 for

recreational wings to about 16.5 for modern competition models. An idling

(gliding) Cessna 152 light aircraft will achieve 9:1. Some sailplanes can

achieve a glide ratio of up to 72:1.

The speed range of paragliders is typically

20–75 kilometres per hour (12–47 mph), from stall speed to maximum speed.

Beginner wings will be in the lower part of this range, high-performance wings

in the upper part of the range.[note 2]

For storage and carrying, the wing is

usually folded into a stuffsack (bag), which can then be stowed in a large

backpack along with the harness. For pilots who may not want the added weight

or fuss of a backpack, some modern harnesses include the ability to turn the

harness inside out such that it becomes a backpack.

Forward launch

In low winds, the wing is inflated with a

forward launch, where the pilot runs forward with the wing behind so that the

air pressure generated by the forward movement inflates the wing.

It is often easier, because the pilot only

has to run forward, but the pilot cannot see his wing until it is above him,

where he has to check it in a very short time for correct inflation and

untangled lines before the launch.

Reverse launch

In higher winds, a reverse launch is used,

with the pilot facing the wing to bring it up into a flying position, then

turning around under the wing and running to complete the launch.
