Harness
A pilot with harness (light blue),
performing a reverse launch
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.

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.

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.
每条线的顶部连接到缝在机翼结构中的小织物线圈上,这些织物线圈通常成行排列(即,左右)。**靠近前一行的行称为A线,下一行称为B线,依此类推。典型的机翼将具有A,B,C和D线,但是**近,有一种趋势是将行的行数减少到三行,甚至两行(并从实验上减少到一行),以减少阻力。
滑翔伞线通常由迪尼玛/光谱或凯夫拉尔/芳纶制成。尽管它们看起来很苗条,但这些材料非常坚固。例如,一条直径为0.66毫的线(大约**细)可以具有56千克的断裂强度。
滑翔伞的滑翔率范围从休闲机翼的9.3到现代竞赛模型的约11.3,在某些情况下高达13。为了进行比较,典型的跳伞降落伞将实现约3:1的滑行。悬挂式滑翔机的范围从休闲机翼的9.5到现代竞赛机型的约16.5。空转(滑行)的塞斯纳152轻型飞机将达到9:1。一些滑翔机可以实现高达72:1的滑行比。
滑翔伞的速度范围通常为每小时20-75公里(12-47英里/小时),从失速速度到比较大速度。初学者机翼将位于该范围的下部,高性能机翼将位于该范围的上部。
为了存放和携带,机翼通常被折叠成一个行李袋,然后可以与安全带一起存放在一个大背包中。对于可能不希望增加背包重量或烦恼的飞行员,一些现代安全带具有将安全带内翻的功能,从而使其成为背包。
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.

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. 无锡小型滑翔伞要多少钱
