1. CHARACTERISTICS
1.1 WHO IS IT DESIGNED FOR?
The HOOK 2 has been designed for pilots who want to discover their true
potential pushing their boundaries of cross country and in flight exploration
to new found levels. The HOOK 2 is a glider of performance, confidence
and security, exactly what the progressing pilot has been searching for. A
glider designed with Niviuk passion and tradition to bring you elegance,
performance and pleasure without compromise.
1.2 CERTIFICATION
HOOK 2 has successfully received the EN B and LTF 1-2 certifications. These
certifications are confirmation of the excellent stability and security of the
HOOK 2.
The results of both tests can be seen on the last pages of this manual.
1.3 IN FLIGHT BEHAVIOUR
The NIVIUK Team has carried out extensive and meticulous design work.
As a consequence of several prototypes and many hours of test flights
numerous adjustments were made. These prototypes were then tested in all
types of flight conditions. This intense development work supported by the
combined experience of the whole team has achieved a wing with unbeatable
behaviour. Light handling, precise response, manoeuvrable, safe, excellent
performance for this category glider, these are just some of the qualities of
this wing. A similar leading edge to that already used on the Koyot offers
incredible stability in turbulence. The leading edge for the HOOK 2 has been
adapted slightly to offer increased energy, so improving performance and
glide yet maintaining the high security already found on the original Hook.
1.4 ASSEMBLY, MATERIALS
The HOOK 2 does not only introduce new design methods but also new
manufacture technologies. Not a single millimetre of error is possible in the
manufacturing process from Olivier’s computer to the cutting of the fabric.
The cutting is done section by section in an extremely meticulous manner.
The numbering and marking of the guideline marks is also done in the same
meticulous way so avoiding errors during this critical process
The lines are semi-automatically manufactured and all the sewing is carried
out under the supervision of our highly trained specialists. Our zero tolerance,
automated process, ensures that each individual part of every canopy are cut
and assembled under the strictest of conditions possible.
All NIVIUK Gliders go through an extremely thorough and efficient final
inspection. Once the final assembly has finished every individual line on each
glider is again carefully measured.
On the completion, each assembled part of every wing is once again
thoroughly inspected to ensure your glider has been made to the highest
standards. It is then carefully packed as recommended in the manual under
maintenance and conservation. NIVIUK Gliders are made using only the
highest quality materials as demanded by the performance, durability, and
the requirements for testing and certification.
Information about construction materials is given on the last pages of this
manual.
1.5 ELEMENTS, COMPONENTS
The HOOK 2 is delivered to you together with a series of components that,
although not fundamental to flight, do take an important part in the use,
transport and storage of the paraglider. The glider is delivered together
with a rucksack, large enough for all of the equipment to fit inside, once
appropriately packed. The rucksack is designed to make transport on foot as
Page 5
5
pleasant as possible. An internal bag, intended to protect the HOOK 2 from
possible damage, during storage is also supplied.
The glider strap allows you to fold the wing as small as possible. Furthermore
you will find the accelerator bar, which completes the acceleration gear of
the wing, a small fabric repair kit made of self-adhesive ripstop and a user’s
manual with the answers all our questions about our new HOOK 2.
2. UNPACKING AND ASSEMBLY
2.1 CHOOSE AN APPROPRIATE LOCATION
We recommend that you unpack and assemble your wing on a school slope
or a flat clear area without too much wind and free of all obstacles. These
conditions will allow you to carry out all the steps required for you to check
and inflate the HOOK 2.
We recommend that an instructor or a retailer supervise the entire procedure,
as only they are qualified to resolve any questions or concerns in a safe and
professional way.
2.2 PROCEDURE
Take the paraglider out of the rucksack, open it and spread it open with the
lines on top of the underside and position the wing as if you were about to inflate
it. Check the condition of the fabric and the lines, making sure there are no
abnormalities. Check the maillons that attach the lines to the risers are properly
closed and locked. Identify in order the A, B, C, D and brake lines and ensure
they fit to the corresponding risers. Make sure that there are no ties or knots.
2.3 ASSEMBLY OF HARNESS
Correctly place the risers on the harness karabiners. The risers and lines
should not have any twists and they should be in the right order. Check that
the harness buckles are correctly locked.
2.4 TYPE OF HARNESS
The HOOK 2 can be flown with many types of harness, school or competition
without any problems. During development and testing we have calculated
that a distance of 42 to 50cm between the harnesses karabiners (depending
on the design and size of your harness) should offer the best compromise for
safety, handling and feedback.
NB. Incorrect adjustment can seriously affect the piloting of the glider.
A distance, which is too wide between the karabiners, may provide more
feedback but could affect the overall stability of the glider. A distance,
which is too narrow between the karabiners, would provide less feedback
but also increase any risk of developing a twist in during a large collapse.
2.5 ASSEMBLY OF THE ACCELERATOR
The acceleration mechanism of the HOOK 2 works when you push with your
feet on the accelerator bar, this is supplied with the equipment. On delivery
the accelerator bar has not yet been installed and it is recommended that it
be correctly fit before your first flight. Most harnesses are equipped with a
pre-installed acceleration system. When fitting any accelerator system ensure
that all preinstalled items within the harness, such as roller pulleys are used
correctly. After fitting, take into account that you will have to adjust the length
of the accelerator lines for correct use. This will vary according to the length
of the pilot’s legs!
We recommend that you carry out the fitting of the acceleration system,
whilst suspended and sat in the harness, most paragliding schools have this
sort of specialised equipment.
2.6 INSPECTIONS AND WING INFLATION ON THE GROUND
Once you have checked all the equipment and made sure that the wind
conditions are suitable, inflate your HOOK 2 as many times as necessary in
order to become acquainted with the wing’s behaviour. The HOOK 2 inflates
Page 6
6
easily and smoothly. An excess of energy is not necessary and the wing will
inflate with minimum pressure on the harness. This may be assisted by using
the A lines. Do not pull on them, just lift to accompany the natural rising
movement of the wing. Once the wing is in the 12 o’clock position, simply apply
correct pressure on the brake lines and the HOOK 2 will sit over your head.
2.7 ADJUSTING THE BRAKES
The length of the main brake lines is adjusted at the factory to the length
established during certification. However, the length can be changed to
adapt to the pilot’s flying style. Nevertheless, we recommend that you fly for
a while with these, set at the original length. If you then decide to change
the length of the brake lines, untie the knot, slide the line through the brake
link to the desired length, and strongly re-tie the knot. Qualified personnel
should carry out this adjustment. You must ensure that this adjustment does
not slow down the glider without any pilot input. Both brake lines should be
symmetrical and measure the same length. The most recommended knots
are the clove hitch knot or bowline knot.
If you do change the length of the brake line, take care to then adjust the
accelerator accordingly. It is important that the brakes are released when
you push on the speed bar. If you have tension on the brake lines whilst
you are accelerating the possibility of a frontal collapse is increased. It
should be noted that whilst accelerating the C riser will naturally move
upwards and apply tension to the brake lines.
3. THE FIRST FLIGHT
3.1 CHOOSE THE RIGHT LOCATION
We recommend that the first flight with your HOOK 2 be made on a smooth
slope (a school slope) or in your usual flying area.
3.2 PREPARATION
Repeat the procedures detailed in chapter 2 (UNPACKING AND ASSEMBLY)
in order to prepare your HOOK 2.
3.3 FLIGHT PLAN
Draw out a flight plan before take-off in order to avoid possible flight errors
and minimise risk.
3.4 PRE-FLIGHT CHECK LIST
Once you are ready, but before you take-off, carry out another equipment
inspection. Ensure correct installation of all equipment and that all lines are
free of hindrances or knots. Check and ensure that the weather conditions
are suitable for your own flying ability.
3.5 WING INFLATION, CONTROL, AND TAKE-OFF
Smoothly and progressively inflate the wing (chapter 2.6 INSPECTION
AND WING INFLATION ON THE GROUND). The HOOK 2 inflates easily
and does not require excessive force. It does not tend to over-fly you, so
the wing inflation phase can be carried out without worry. These take off
characteristics provide a perfect control phase and enough time for the pilot
to decide whether to accelerate and take off.
Whenever the wind speed allows it, we recommend a reverse launch
technique, this type of launch allows you to carry out a better visual check of
the wing. The HOOK 2 is especially easy to control in this position, especially
in strong winds. However, wind speeds up to 25 to 30 km/h are considered
strong and extra consideration should be given to any thought of flight.
Preparation and positioning of the wing on the launch site is especially
important. Choose a location, which is appropriate for the direction of the
wind, and position the paraglider in a semi-circle, emulating the shape of the
canopy in flight. All this will assist in a trouble free take-off.
Page 7

3.6 LANDING
The HOOK 2 lands excellently, it transforms the wing speed into lift on the
pilot’s demand, allowing an enormous margin of error. You will not have to
wrap the brake lines around your hand to improve braking efficiency.
3.7 PACKING
Use of a correct folding method is important for extending the useful life of
your paraglider. It should be folded like an accordion, ensuring that the (SLE)
leading edge reinforcements remain flat. This method will keep the profile in
good shape without altering its form or its performance. Please ensure that
the reinforcements are not bent or twisted. The wing does not have to be
tightly folded, if you do so it may damage the material or the lines.
4. IN FLIGHT
4.1 FLYING IN TURBULENCE
The HOOK 2 has an excellent profile, which will deal with the very different
meteorological conditions likely to be met during sensible flying. This profile
allows the best possible handling, stability and safety in turbulent conditions.
Nonetheless, the pilot always has to pilot according to the prevailing weather
conditions, the pilot is always the ultimate safety factor.
We recommend active piloting, making the necessary fine adjustments to
keep the wing in control and above your head. He/she should stop braking
to allow it to fly at the required wing speed after a correction is made. Do not
maintain any correction for longer than necessary (braked) this would cause
the wing to enter into critical flying situation. Whenever necessary, control a
situation, react to it and then re-establish the required speed.
4.2 POSSIBLE CONFIGURATIONS
We recommend that training to master these manoeuvres be carried out
under the supervision of a competent school.
Asymmetric collapse
In spite of the high stability of the profile of the HOOK 2, heavy turbulent
conditions may cause part of the wing to collapse asymmetrically. This
usually happens when the pilot has not foreseen this possible reaction of
the wing. When the wing is about to experience an asymmetric collapse the
brake lines and the harness will transmit a loss of pressure to the pilot. To
prevent the collapse from happening, pull the brake line corresponding to the
compromised side of the wing, this will increase the angle of incidence. If the
collapse does happen the HOOK 2 will not react violently, the turn tendency is
very gradual and it is easily controlled. Lean your body towards the side that
is still flying in order to counteract the turn and maintain a straight course,
if necessary slightly slow down the same side but do not brake it excessively
as this may induce a stall. The collapse will normally open by itself but if that
does not happen, pull completely on the brake line on the side which has
collapsed. Do this with a smooth and firm movement. You may have to repeat
this operation to encourage the re-opening. When the collapse has been
solved, remember to allow the wing recover its flying speed.
Symmetric collapse
In normal flying conditions the design of the HOOK 2 ensures that a
symmetric collapse is quite improbable. The profile of the wing has been
designed to widely tolerate extreme changes in the angle of incidence. A
symmetric collapse may occur in heavy turbulent conditions, on entry or
exit of strong thermals or lack of adapting the use of the accelerator to the
prevailing air conditions. Symmetrical collapses usually re-inflate without the
glider turning but you can symmetrically apply the brake lines with a quick
deep pump to quicken the re-inflation. Release the brake lines immediately
to recover optimum flight speed.
Page 8
8
Negative spin
This configuration is out of the normal flight behaviour of the HOOK 2. Certain
circumstances however, may provoke this configuration such as trying to turn
when the wing is flying at very low speed (while heavily braking). It is not easy
to give any recommendations about this situation since it varies depending
on the circumstances. Remember that you should restore the relative air
speed over the wing. To achieve this, progressively reduce the pressure on
the brake lines and let the wing gain speed. The normal reaction would be
a lateral surge with a turn tendency no greater than 360º before restoring to
normal flight conditions.
Parachutal stall
If it does occur, the feeling would be that the wing would not have any
forward motion, you would feel a sense of instability and a lack of pressure
on the brake lines, although the canopy would appear to be correctly inflated.
The correct reaction would be to release the pressure on the brake lines
and push the A lines forward or rather lean your body to any side WITHOUT
PULLING ON THE BRAKE LINES.
Deep stall
The possibility of the HOOK 2 falling into this configuration during normal
flight is very unlikely. This could happen if you are flying at a very low speed,
whilst over steering in a number of manoeuvres and in turbulent conditions.
To provoke a deep stall you have to take the wing to minimum flight speed
by symmetrically pulling the brake lines, when you reach this point, continue
pulling until you reach 100% and then hold. The glider will first fall behind
you and then situate itself above you, rocking slightly, depending on how
the manoeuvre was carried out. When you start to initiate a stall, be positive
and do not hesitate. Do not release the brake lines when half way through
the manoeuvre as this would cause the glider to surge violently forward with
great energy and may result in the wing below the pilot. It is very important
that the pressure on the brake lines is maintained until the wing is well
established vertical above. To regain normal flight conditions, progressively
and symmetrically release the brake lines, letting the speed be re-established.
When the wing reaches the maximum advanced position ensure that the
brakes are fully released. The wing will now surge forward, this is necessary
so that air speed is completely restored over the wing. Do not over brake
at this point because the wing needs to recover speed to quit the stall
configuration. If you have to control a possible symmetrical front stall, briefly
and symmetrically pull on the brake lines and let go even when the wing is
still ahead of you.
Wing tangle (Cravat)
A wing tangle may happen after an asymmetric collapse, the end of the wing
is trapped between the lines (Cravat). This situation could rapidly cause the
wing to turn, although it depends on the nature of the tangle. The correction
manoeuvres are the same as those applied in the case of an asymmetrical
collapse, control the turn tendency by applying the opposite brake and lean
your body against the turn. Then locate the line that reaches the stabiliser
that is trapped between the other lines. This line has a different colour and
belongs to the external lines of the C riser.
Pull on this line until it is tense, this should help to undo the wing tangle. If
you cannot undo the tangle, fly to the nearest possible landing spot, control
the flying course with your body movements and a little pressure on the
opposite brake. Be careful when attempting to undo a tangle if you are flying
near a mountainside or near to other paragliders, you may lose control of the
flying course and a collision may occur.
Over Input
Most flying incidents are caused by incorrect actions of the pilot, which
chained one after another creates abnormal flying configurations (a cascade of
incidents). You must to remember that over handling the wing will lead to critical
levels of functioning. The HOOK 2 is designed always to try to recover normal
flight by itself, do not try to over handle it. Generally speaking, the reactions of
the wing, which follow over handling, are neither due to the input made or the
intensity, but the length of time the pilot continues to over handle. You have to
allow the profile to re-establish normal flight speed after any type of handling.
Remember – “Minimum sufficient input”
Page 9
9
4.3 USING THE ACCELERATOR
The profile of the HOOK 2 has been designed to remain stable through its
entire speed range. The speed bar is very usable in competition but it’s
advisable to have a good training to be able to anticipate possible collapses.
Active piloting is always required whilst using the accelerator. Smooth
application both on and off is the most efficient and safe way to operate the
speed system, if it is applied quickly in an “on/off” motion the anticipation
would not be part of the pilots flying and a deflation is more likely. It is useful
to accelerate when flying in strong winds or in extreme descending air. When
under acceleration the wing profile becomes more sensitive to possible
turbulence and closer to a possible frontal collapse. If you feel any pressure
loss, you should smoothly release the pressure on the accelerator and pull
slightly on the brake lines to increase the angle of incidence. Remember that
you must re-establish the flight speed after correcting the incidence.
It is NOT recommended to accelerate near to the mountainside or in very
turbulent conditions. If necessary you will have to constantly adjust the
movements and pressure on the accelerator whilst constantly adjusting the
pressure applied to the brake lines. This balance is considered to be “active
piloting.”
4.4 FLYING WITHOUT BRAKE LINES
If, for any reason at all, you cannot use the brake lines of your HOOK 2
you will have to pilot the wing using the D-risers and your body weight to
fly towards the nearest landing area. The D-lines steer easily because they
are not under pressure, but you must to be careful not to over handle them
causing a stall or negative turn. To land you have to let the wing fly at full
speed and just before reaching the ground you will have to pull symmetrically
on both the D-risers. This braking method is not as effective as using the
brake lines so you will land at a higher speed.
4.5 KNOTS IN FLIGHT
The best way to avoid these knots and tangles is to inspect the lines
before you inflate the wing for take-off. If you notice a knot before take off,
immediately stop running and do not take-off. If you have taken-off with a knot
you will have to correct the drift by leaning on the opposite side of the knot
and gently apply the brake line on that side too. You can gently try to pull on
the brake line to see if the knot becomes unfastened or try to identify the line
with the knot in it. Try to pull the identified line to see if the knot releases. Be
very careful when trying to remove a knot. When there are knots in the lines
or when they are tangled, do not pull too hard on the brake lines, there is an
increased risk of the wing to stalling or negative turn being initiated.
Before trying to remove a knot, make sure there are no pilots flying nearby and
never try these manoeuvres near the mountainside. If the knot is too tight and
you cannot remove it, carefully and safely fly to the nearest landing place.
5. LOSING HEIGHT
Modern gliders offer excellent performance and a high level of safety but
sometimes the meteorological conditions can quickly develop or deteriorate,
becoming so dangerous that the need to rapidly descend becomes a priority.
We therefore advise that you carefully read this manual and if necessary,
complete an SIV course with an authorised instructor.
5.1 EARS
Big ears are a moderate descent method, reaching –3 or –4 m/s, ground
speed reduces slightly between 3 and 5 km/h and piloting becomes limited.
The angle of incidence and the surface wing load also increases. Push on the
accelerator to restore the wing’s horizontal speed and the angle of incidence.
To pull big ears take the outermost A-lines of both stabilizers as high up as
possible and pull on them outward and downward, the wingtips will then
fold in. Let go of the lines and the big ears will re-inflate automatically. If
Page 10
10
they do not re-inflate, gently pull on one of the brake lines and then on the
opposite one. In order to prevent any alteration in the angle of incidence, we
recommend that you re-inflate the glider asymmetrically. This is particularly
important if you are flying near the ground.
5.2 B-LINE STALL
When you carry out this manoeuvre, the wing stops flying, it loses all
horizontal speed and you are not in control of the paraglider. The air
circulation over the profile is interrupted and the wing enters into a situation
similar to parachuting.
To carry out this manoeuvre you have to take the B-lines below the maillons
and symmetrically pull both of them down (approx. 20-30cms) and then
hold this position. The initial phase is quite physical (hard resistance)
which means that you will have to pull strongly until the profile of the wing
is deformed, when this happens the required force will then significantly
reduce. To maintain this manoeuvre you must continue to hold the B Lines
in the pulled down position. The wing will then become deformed, horizontal
speed drops to 0 km/h and vertical speed increases to –6 to –8 m/s
depending on the conditions and how the manoeuvre has been carried out.
To exit the manoeuvre, simultaneously release both risers, the wing will then
slightly surge forward and then automatically return to normal flight. It is better
to let go of the lines quickly rather than slowly. This is an easy manoeuvre but
you must remember that the wing stops flying, it loses all horizontal movement
and its reactions are very different compared to normal flight.
5.3 SPIRAL DIVE
This is a more effective way for rapidly losing height. You have to know that,
the wing can gain a lot of speed and the increase in G’s will be substantial.
This can cause a loss of orientation and consciousness (blackouts). These
are the reasons why it is best to carry out this manoeuvre gradually so your
capacity to resist the G forces increases and you will learn to fully appreciate
and understand the manoeuvre. Always practice this manoeuvre when flying
at high altitude.
To start the manoeuvre, first lean your bodyweight and pull the brake line to
the side to which you are leaning. You can regulate the intensity of the turn
by applying a little outside brake. A paraglider flying at its maximum turn
speed can reach –20 m/s, equivalent 70 km/h vertical speed and stabilize in
a spiral dive from 15 m/s onwards.
These are the reasons why you should be familiar with the manoeuvre and
know how to carry out the exit methods. To exit this manoeuvre you must
progressively release the inside brake and also momentarily apply outside
brake. Whilst doing this you must also lean your bodyweight towards the
outside. This exit manoeuvre must to be carried out gradually and with
smooth movements so you can feel the pressure and speed changes at the
same time. On exiting this manoeuvre the glider will rock briefly with a lateral
surge, the intensity will depend on how the manoeuvre has been carried out.
Practice these movements at sufficient altitude and in moderation.
We recommend not using this technique often because this will age your
glider and lines prematurely.
5.4 THE WEATHER TECHNIQUE
This technique is the most simple descent technique, allowing your glider to
remain in normal flight without forcing the structure. Locate the metrological
descend zone (sinking air) and turn in it as you would do for ascending.
6. SPECIAL METHODS
6.1 TOWING
The HOOK 2 does not experience any problem whilst being towed. Only
qualified personnel should handle the qualified equipment to carry out this
operation. The wing has to be inflated in the same way as in normal flight.
Page 11
11
6.2 ACROBATIC FLIGHT
Although the HOOK 2 has been tested by expert acrobatic pilots in extreme
situations, it HAS NOT been designed for acrobatic flight and we DO
NOT RECOMMEND THE USE OF THIS GLIDER for that use. We consider
acrobatic flight to be a form of piloting that is different to normal flight. To
learn safely how to master acrobatic manoeuvres you should attend lessons,
which are carried out and supervised by a qualified instructor over water.
Extreme manoeuvres take you and your wing to centrifugal forces that can
reach 4 to 5g. Materials will wear more quickly than in normal flight. If you do
a lot of extreme manoeuvres we recommend a full line check at least every
year or every 100h, whichever is the soonest.
7. CARE AND MAINTENANCE
7.1 MAINTENANCE
Careful maintenance of your equipment will ensure continued performance.
The fabric and the lines do not need to be washed, if they become dirty, clean
them gently with a soft damp cloth. If your wing becomes wet with salty water,
immerse it in fresh water and dry it away from direct sunlight. The sunlight may
damage the materials of your wing and cause premature aging. Once you have
landed, do not leave the wing in the sun, store it properly. If you use your wing
in a sandy area, try to avoid the sand from entering the cell openings of the
leading edge. If sand is inside the wing, remove it before folding.
Competition lines, which were used in the past, were more vulnerable to
premature wear and ageing but the new line materials used on the HOOK 2
now ensure a much longer working life. However they still demand regular
checks with careful attention to wear and tear. We advise a full inspection
of the lines every 12 months or 100 hours, whichever is the soonest at a
specialised paragliding repair centre. Rocks and hard ground are obviously
far more abrasive than grassed an area, that’s why we do not advise the
HOOK 2 for ground handling practice.
7.2 STORAGE
It is important that the wing is correctly folded when stored. Store your
flying equipment in a cool, dry place away from solvents, fuels or oils. It
is not advisable to store your flying equipment in the trunk of your car.
Temperatures inside a car parked in the sunlight, can be very high. Inside a
rucksack and in the sunlight temperatures can reach 60ºC. Weight should
not be laid on top of the equipment. It’s important that your glider has been
folded correctly and stored well. If you have to store it for a long time (over
one month) we advice (if possible) to take the glider out of the bag and leave
it as a tube on a dry and cool surface.
7.3 CHECK-UPS AND CONTROLS
You should ensure that your HOOK 2 is periodically serviced and checked
at your local repair centre every 12 months or 100hrs (whichever is the
soonest). This will guarantee that your HOOK 2 will continue to function
properly and therefore continue fulfilling your requirements. As previously
mentioned, you should systematically check your lines visually before each
take-off.
7.4 REPAIRS
If the wing is damaged, you can temporarily repair it by using the selfadhesive rip stop which you will find in the repair kit, providing no stitches are
involved in the tear. Any other type of tear must be repaired in a specialised
repair shop or by qualified personnel. Do not accept a home repair.
8. SAFETY AND RESPONSIBILITY
It is well known that paragliding is considered a high-risk sport, where safety
depends on the person who is practising it.
Wrong use of this equipment may cause severe injuries to the pilot, even
death. Manufacturers and dealers are not responsible for any act or accident
Page 12
12
that may be the result of practicing this sport. You must not use this
equipment if you are not trained. Do not take advice or accept any informal
training from anyone who is not properly qualified as a flight instructor.
9. GUARANTEE
The entire equipment and components are covered by a 2-year guarantee
against any manufacture fault.
The guarantee does not cover misuse or abnormal use of the materials.
