1. CHARACTERISTICS
1.1 WHO IS IT DESIGNED FOR?
The denition of sharing:
- experience together
- y together.
Previously the pleasure of sharing the hike & y experience was difcult
for tandem pilots. The dream seemed unreachable. All their ying
experiences excluded their partners and friends.
Now both pilot and passenger can share the adventure and thrill of hike
& y and vol-biv with total condence and safety.
Designed for leisure ights as well as commercial ights, this EN B
certied dual glider is the lightest tandem on the market. Weighing only
3.3 kg and with an extremely small packing volume, this single-surface
wing has the capacity to carry up to 190 kg.
Only the aeronautical authorities of respective countries can determine
pilot competence.
1.2 CERTIFICATION
The BI SKIN 2 P was certied at the Swiss testing house Air Turquoise
S.A. in accordance with European norms EN 926-2:2013, EN 926-1:2015
& LTF 91/09; it successfully passed all tests and was certied as EN B.
Registration number: PG 1100.2016
Shock test to 1.200 daN.
Load test to 8G 203 kg.
We recommend pilots read the ight test report by Air Turquoise. The
report contains all the necessary information on how the paraglider
reacts during each of the tested manoeuvres.
For further information on the ight test and the corresponding
certication number, please see the nal pages of this manual.
1.3 IN-FLIGHT BEHAVIOUR
Niviuk developed this wing by adopting very specic goals: to achieve
optimum performance while minimising weight and volume in order to
achieve an easily transportable wing; excellent handling; to facilitate
more control for the pilot and, above all, to maintain a very high degree
of safety.
We have succeeded in having the wing transmit the maximum feedback
in an understandable and comfortable way so that the pilot can focus on
piloting.
In all aspects of ight, the wing is very solid and stable. The glide is very
smooth. During glide, the wing maintains altitude well and the prole
remains stable. Turning is precise and does not require much physical
strength. The glider is responsive to brake input. The wing is very easy
to inate even in nil-wind, it requires an extremely short takeoff (ideal
especially in the mountains) and provides a smooth and precise landing.
Flying this wing is very intuitive, with with clear feedback about the
airmass. It responds to the pilot’s inputs effectively and even in turbulent
conditions it remains stable and solid.
The BI SKIN 2 P ies efciently. It enters thermals with sufcient speed
to centre in the lift and climbs progressively. The handling is progressive
and effective for even more ying pleasure under an exciting wing of
extraordinary quality.
It is lightweight, even lighter in ight and easy to pilot, with outstanding

5
turbulence buffering and a surprising range of speed for incredible glides.
1.4 CONSTRUCION, MATERIALS
The BI SKIN 2 P has all the technological innovations used on other
Niviuk gliders and is built with the most careful selection of current
materials. It has all the current technology and accessories available to
improve pilot comfort whilst increasing safety and performance.
Titanium Technology (TNT) – A revolutionary technique using titanium.
Using Nitinol in the internal construction provides a more uniform prole
and reduces the weight to gain efciency in ight. Nitinol provides the
highest level of protection against deformation, heat or breaks.
SLE - The use of the SLE considerably reduces the amount of Mylar
which was used in previous Niviuk wings and this also reduces the
weight of the leading edge and therefore the wing inates more easily
than one without this system.
3DP - The optimal distribution of cloth tension has been achieved by
cutting individual sections, paying attention to the orientation of the
fabric and using 3D modelling.
3DL- There is an additional seam on the leading edge for a cleaner
prole, no creases for less drag and a better load distribution.
Interlock System (IKS).- the IKS is a connection system that allows the
risers to be connected to different parts of the wing, such as the lines or
the harness. The IKS technology is a step towards greater lightness in
wings and equipment, without sacricing effectiveness and providing the
same degree of safety and strength.
IKS1000 is included in the pack.

riser side.
Push the upper looped end
downward through the elastic
sleeve (not small diameter tube)
and then through the reinforced
loop end where the black tab
is located.

The use of these technologies is a big technological leap forward in
building wings and a big improvement in ight comfort.
For the construction process of BI SKIN 2 P we use the same criteria,
quality controls and manufacturing processes as in the rest of our range.
From Olivier Nef’s computer to fabric cutting, the operation does not
allow for even a millimetre of error. The cutting of each wing component
is performed by a rigorous, extremely meticulous automated computer
laser-cutting robotic arm. This program also paints the guideline markers
and numbers on each individual fabric piece, thus avoiding errors during
this delicate process.
The jigsaw puzzle assembly is made easier using this method and
optimises the operation while making the quality control more efcient.
All Niviuk gliders go through an extremely thorough and detailed nal
inspection. The canopy is cut and assembled under strict quality control
conditions, facilitated by the automation of this process.
Continue with the
procedure in a
counterclockwise motion
by pushing the looped
end through the riser.
Push the looped end rst upward
through the elastic sleeve (not
small diameter tube) and through
the lines again following the
same pattern.

1.5 ELEMENTS, COMPONENTS
The BI SKIN 2 P is delivered with a series of accessories that will greatly
assist you in the maintenance of your paraglider:
- An inner bag to protect the wing during storage and transport.
- An adjustable compression strap to compress the inner bag and reduce
its volume.
- A repair kit with self-adhesive Ripstop tape in the same colour as the
wing and spare parts to protect the maillons.
-A Kargo bag. It is not included in the pack, but we recommend to get
it. This bag is large enough to hold all equipment comfortably and with
plenty of space.
2. UNPACKING AND ASSEMBLY
2.1 CHOOSE THE RIGHT LOCATION
We recommend unpacking and assembling the wing on a training hill or
a at clear area without too much wind and free of obstacles. It will help
you to carry out all the recommended steps required to check and inate
the BI SKIN 2 P.
We recommend the whole installation procedure is supervised by a
qualied professional instructor or ofcial dealer. Only they can address
any doubts in a safe and professional way.
2.2 PROCEDURE
Take the paraglider out of the rucksack, open and unfold it on the ground
with the lines positioned on the undersurface, oriented in the direction of
ination. Check the condition of the fabric and the lines for defects. Pay
attention to the maillons and IKS connecting the lines to the risers to make
sure they are fully closed and tightened. Identify, and if necessary untangle,
Every wing is individually checked with a nal visual inspection.
The fabric used guarantees lightness, strength and durability without
fading.
The lines are made from unsheathed Aramid and Dyneema.
The line diameter has been calculated depending on the workload and
aims to achieve the required best performance with the least drag.
The lines are semi-automatically cut to length and all the sewing is
completed under the supervision of our specialists.
Every line is checked and measured once the nal assembly is
concluded.
Each glider is packed following specic maintenance instructions as
recommended by the fabric manufacturer.
Niviuk gliders are made of premium materials that meet the requirements
of performance, durability and certication that the current market
demands.
Information about the various materials used to manufacture the wing
can be viewed in the nal pages of this manual.

the A, B, C and D-lines, the brake lines and corresponding risers. Make
sure that there are no knots.
2.3 CONNECTING THE HARNESS
Correctly connect the risers to the spreader bar attachment points so
that the risers and lines are correctly ordered and free of twists.
Check that the carabiners are properly fastened and securely locked.
Next, the pilot’s harness and then the passenger’s harness must be
attached.
2.4 HARNESS TYPE
The pilot should choose the type of harness to use. The BI SKIN 2 P can
be own with all current harness types, from standard tandem (heavy
duty) harnesses to ultralight models.
2.5 SPEED SYSTEM - TRIMMERS
The BI SKIN 2 P is not tted with a speed-bar.
The speed system is engaged when the trimmers are opened.
The trimmers are installed in the factory and the pilot only needs to
check their proper operation and adjustment.
The BI SKIN 2P has four risers divided into four line areas. The trimmers
are situated on the D-riser and have a maximum travel of 6 cm. The use
of the trimmers results in changes to the speed and reactions of the
wing.
The pilot is responsible for the trimmer setting.
The trimmer setting and symmetry must be constantly checked during
ight and before every takeoff.
The trimmer system is set by the pilot, i.e. it does not return to its point
of origin, but remains in place until the pilot decides to release/change
the position.
Engaging and releasing the trimmers is effective and quick as well as
sensitive and accurate.
When the trimmer is in the neutral position, the wing will y at a lower
speed with greater glide; when the trimmer is released, the wing will y
with higher speed and worse glide.
Trimmers in neutral position A, B, C, D-risers aligned
Trimmers open: Difference A= B+1.5cm, C+3cm, D+6cm
We recommend the trimmers are set in the neutral position during
take off. However, sometimes the circumstances of the takeoff require
releasing trimmers to adjust the speed of the wing ination. The greater
distance the trimmers are released, the faster the wing will inate and,
consequently, the pilot will have to exert more control over the wing at
this stage.
Once in the air, the pilot can adjust the trimmer to the required speed:
slow (trimmers closed), neutral (trim speed) or fast (trimmers open).
Using the trimmers:
The pilot must engage the trimmers manually. They are situated on both
D-risers. To open the trimmers, press the trim tab inwards until the tape
is released and release the trim tab when in the required position.
To close the trimmers, pull the tape down using the handle and release
when you reach the required position.
Once engaged, the trimmers must be set symmetrically.
The trimmers cannot be used for steering the glider. The pilot should note

9
that when releasing trimmers, the brake handle rises the same distance
as the trimmers travel.
2.6 INSPECTION AND WING INFLATION ON THE GROUND
After your gear has been thoroughly checked and the weather conditions
deemed favourable for ying, inate your BI SKIN 2 P as many times as
necessary to familiarise yourself with its behaviour. Inating the
BI SKIN 2 P is easy and should not require a great deal of physical effort.
Inate the wing with a little pressure from the body using the harness.
This may be assisted by using the A-lines. Do not pull on them; just
accompany the natural rising movement of the wing. Once the wing is
inated to the overhead position, appropriate control with the brakes will
be sufcient to hold it there.
We recommend practising inating the wing in various wind conditions as
the BI SKIN 2 P inates much faster than conventional wings.
Groundhandling the wing is important as the rapid ination may may
surprise the pilot if the launch has not been practised before the rst ight.
2.7 ADJUSTING THE BRAKES
The length of the main brake lines are adjusted at the factory and
conform to the length stipulated during certication. However, they can
be changed to suit the pilot’s ying style. It is advisable to y with the
original setting for a period of time to get used to the actual behaviour of
the BI SKIN 2 P. In case it is necessary to modify the brake length, loosen
the knot, slide the line through the brake handle to the desired point and
re-tighten the knot rmly.
Only qualied personnel should carry out this adjustment. You must
ensure that the modication does not affect the trailing edge and
slow the glider down without pilot input. Both brake lines should be
symmetrical and of the same length. We recommend using a clove hitch
or bowline knot.
3. THE FIRST FLIGHT
3.1 CHOOSING THE RIGHT LOCATION
For the rst ight we recommend going to your usual ying area and that
a qualied instructor is present and supervising the entire procedure.
When arriving at the take-off, the pilot should assess the following
conditions: wind speed and direction, possible areas of rotor, take-off is
clear of obstacles, etc. A dened ight plan should be formulated and
this should include taking note of the topography, obstructions and risk
areas to avoid. The take-off zone should be sufciently large and free of
obstacles.
Before take off, inspect the wing, harness, helmet and any other
equipment.
It is essential to adapt each launch to the varying conditions and sites.
The conditions must also be suitable for the pilot’s skill level and
experience.
Just because the wing is fast, pilots should not make the mistake of
underestimating the conditions and taking off in unsuitable and unsafe
circumstances.
3.2 PREPARATION
Repeat the procedures detailed in chapter 2 UNPACKING AND
ASSEMBLY to prepare your equipment.

10
3.3 FLIGHT PLAN
Planning a ight before taking off to avoid possible problems later is
always a good idea.
3.4 PRE-FLIGHT CHECK LIST
Once ready, but before taking off, conduct another equipment inspection.
Conduct a thorough visual check of your gear with the wing fully open,
the lines untangled and properly laid out on the ground to ensure that all
is in working order. Be certain the weather conditions are suited to your
ying skill level.
3.5 WING INFLATION, CONTROL, AND TAKE-OFF
Smoothly and progressively inate the wing. Inating of the BI SKIN 2 P
is easy and does not require a lot of energy. The wing rises fast and the
pilot must anticipate this in order to have control during this phase. The
wing will take the load immediately, making it easier to take off in rough
terrain.
If the wind permits, we recommend a reverse launch, as this allows a
better visual inspection of the wing during ination. In “strong” winds,
the BI SKIN 2 P is especially easy to control using this launch technique.
Winds of 25 to 30 km/h are considered strong for paragliding.
Correctly setting up the wing on the ground before take off is especially
important. Choose an appropriate location facing the wind. Position the
paraglider in a crescent conguration to facilitate ination. A clean wing
layout will ensure a trouble-free take off.
3.6 LANDING
The BI SKIN 2 P lands excellently, it converts the wing speed into lift at the
pilot’s demand, allowing an enormous margin of error. Wrapping the brake
lines around your hand to get greater braking efciency is not necessary.
3.7 PACKING
The BI SKIN 2 P has a complex leading edge, manufactured using a
variety of different materials and it must be packed carefully. A correct
folding method is very important to extend the useful life of your paraglider.
It should be concertina-packed, with the leading edge reinforcements at
and the exible rods stacked one on top of the other. This method will
keep the prole in its original shape and protect the integrity of the wing
over time. Make sure the reinforcements are not bent or folded. It should
not be folded too tightly to avoid damage to the cloth and/or lines.
At Niviuk we have designed the NKare Bag, a bag designed to assist you
with rapid packing which helps maintain the integrity of the leading edge
and its internal structures in perfect condition.
4. IN FLIGHT
We recommend that you read the certication test report.
The report contains all the necessary information on how the BI SKIN 2 P
reacts during each of the tested manoeuvres.
It is important to point out that the appropriate response to each adverse
manoeuvre can vary from size to size; even within the same size at
maximum or minimum load the behaviour and reactions of the wing may
vary.
Having the knowledge that the testing house provides through the test
report is fundamental to learning how to deal with possible situations.
