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]

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.

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.
滑翔伞拖曳发射,波兰米罗斯瓦维采
滑翔伞降落在印度Azheekkod海滩
与所有飞机一样,发射和降落都是在风中完成的。机翼通过奔跑或被拉动或存在的风被置于气流中。机翼在飞行员上方向上移动到可以运载乘客的位置。然后将飞行员从地面抬起,经过一段安全时期后,可以坐在他的安全带中。与跳伞运动员不同,滑翔伞与悬挂式滑翔伞一样,在此过程中不会随时“跳”起来。在高地上使用了两种发射技术[20],在平地地区使用了一种辅助发射技术:
向前发射
在低风中,机翼通过向前发射而膨胀,飞行员在前进时将机翼向后移动,以便向前运动产生的气压使机翼膨胀。
这通常更容易,因为飞行员只需要向前跑,但是飞行员直到机翼上方都看不到他的机翼为止,在那里他必须在很短的时间内检查一下机翼,以确保发射前有正确的充气和不纠缠的线。
These developments were combined in June
1978 by three friends, Jean-Claude Bétemps, André Bohn and Gérard Bosson, from
Mieussy, Haute-Savoie, France. After inspiration from an article on slope
soaring in the Parachute Manual magazine by parachutist and publisher Dan
Poynter,[7] they calculated that on a suitable slope, a "square"
ram-air parachute could be inflated by running down the slope; Bétemps launched
from Pointe du Pertuiset, Mieussy, and flew 100 m. Bohn followed him and glided
down to the football pitch in the valley 1000 metres below.[8]
"Parapente" (pente being French for "slope") was born.
From the 1980s, equipment has continued to
improve, and the number of paragliding pilots and established sites has
continued to increase. The first (unofficial) Paragliding World Championship
was held in Verbier, Switzerland, in 1987,[9] though the first officially
sanctioned FAI World Paragliding Championship was held in Kössen, Austria, in
1989.[10]
