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.

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.

Europe has seen the greatest growth in

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

5) upper line cascade

6) middle line cascade

7) lower line cascade

8) risers

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]

Land-based practice: Kiting

About that time, David Barish was

developing the "sail wing" (single-surface wing) for recovery of NASA

space capsules – "slope soaring was a way of testing out ... the Sail

Wing."[5] After tests on Hunter Mountain, New York, in September 1965, he

went on to promote slope soaring as a summer activity for ski resorts.[6][7]


Author Walter Neumark wrote Operating

Procedures for Ascending Parachutes, and in 1973 he and a group of enthusiasts

with a passion for tow-launching PCs and ram-air parachutes broke away from the

British Parachute Association to form the British Association of Parascending Clubs

(which later became the British Hang Gliding and Paragliding Association). In

1997, Neumark was awarded the Gold Medal of the Royal Aero Club of the UK.

Authors Patrick Gilligan (Canada) and Bertrand Dubuis (Switzerland) wrote the

first flight manual, The Paragliding Manual in 1985, coining the word

paragliding.

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.
