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.

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.

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.

The top of each line is attached to small

fabric loops sewn into the structure of the wing, which are generally arranged

in rows running span-wise (i.e., side to side). The row of lines nearest the

front are known as the A lines, the next row back the B lines, and so on.[14] A

typical wing will have A, B, C and D lines, but recently, there has been a

tendency to reduce the rows of lines to three, or even two (and experimentally

to one), to reduce drag.

Paraglider lines are usually made from

Dyneema/Spectra or Kevlar/Aramid.[14] Although they look rather slender, these

materials are immensely strong. For example, a single 0.66 mm-diameter line

(about the thinnest used) can have a breaking strength of 56 kg.[15]

Paraglider wings typically have an area of

20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and

weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve,

instruments, helmet, etc. is around 12–22 kilograms (26–49 lb).

Europe has seen the greatest growth in

paragliding, with France alone registering in 2011 over 25,000 active pilots.

The paraglider wing or canopy is usually

what is known in engineering as a "ram-air airfoil". Such wings

comprise two layers of fabric that are connected to internal supporting

material in such a way as to form a row of cells. By leaving most of the cells

open only at the leading edge, incoming air keeps the wing inflated, thus

maintaining its shape. When inflated, the wing's cross-section has the typical

teardrop aerofoil shape. Modern paraglider wings are made of high-performance

non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]
