2. On the wing
Who should fly Orca XX?
If you are an experienced pilot and want to share your joy of flight with the
poor beggars who haven’t tasted it so far, then Orca XX is for you. It will
easily take both of you in the air, safely guide through the thermals and
finally will smoothly put you back on to Earth. On the other hand, if you
prefer to impress your passenger with some swift manoeuvres, Orca XX
won’t let you down with its agility either.
The paraglider is dedicated both for free-flying with passenger and for light
paramotor trikes.
Four-row canopy with rigid cores (Dudek FlexiEdge technology) blends
recent experiences of testing other prototypes employing this technology
with long-standing info gathered over years from happy users of the original
Orca. The aspect ratio and other factors were carefully calculated in order to
make full advantage of new technologies, while retaining optimal proportion
of passive safety, performance and steering for this class.
The aerofoil used in Orca XX has Shark-nose intakes - they help to internal
pressure of the canopy stays stable within wide speed range.
Inner reinforcements, structural cores and mini-ribs perfectly shape and
stabilize the aerofoil. Mini-ribs on the trailing edge keep it slim and decrease
ballooning, radically improving the airflow. Rigging has been redesigned too
- total lines length decreased by 15% as compared to Orca, bringing further
improvements. All in all, we succeeded in creating a perfectly balanced
design, mixing great performance with safety and stability. In turbulence the
paraglider behaves very reassuring and predictable, with efficient damping
of both longitudinal and lateral oscillations.
OrcaXX easily inflates and rises, without lagging behind. Then it stabilizes
and with slight brake action just flies away. On the landing approach it is
enough to brake down a little in order to markedly decrease speed with
ensuing soft touchdown. All tandem pilots appreciate those features, so
we’ve put quite an effort into polishing them to perfection.

DESIGN
Canopy of the Orca XX body was designed in our CSG (Canopy Shape
Guard) system, comprising a number of elements resulting in exceptional
coherence and stability of the shape.
Below you will find a short description of CSG
subsystems.
Orca XX has an elliptic shape with slightly back-swept
wingtips. The canopy is made of doubled cells, with
ribs supported with VSS (V-Shaped Supports) system. Such design
guarantees that the canopy stays rigid, the upper surface is smooth with
correctly reproduced aerofoil, and what is most important we have fewer
suspension points (thus reducing overall lines' length and drag).
Inside the canopy there is RSS (Reinforcing Strap System) applied on the
lower surface. RSS is a ballooning-independent reinforcements system
made entirely of paragliding fabric, effectively stiffening and stabilizing the
canopy.
The aerofoil was perfected with DOA technology
(Dudek Optimized Airfoil). It merges all our
experiences stemming from previous designs and as a
special feature is optimized with dedicated CFD
engineering software.
The air intakes are placed on the lower surface close to
the leading edge, placed so that max pressure point
remains in the area at possibly many states of flight.
They are designed and executed in Shark-nose
technology, meaning specific, concave shape of the
reinforced profile area at its leading edge (the name comes form the very
shape, reminding shark's nose). Due to such shape the intakes can be
smaller and moved a bit back, so that leading edge remains undisturbed and
offers smooth airflow. The internal pressure of the canopy stays stable within
wide speed range. In everyday flying this results in greater resistance to
stalls (e.g. when thermalling) and front collapses at high speeds.
The suspension points areas are additionally reinforced with laminated fabric
so that loads are equally distributed on three planes: vertically (with the ribs),
diagonally (with VSS system) and level through RSS.
All crossports have been prepared with application of OCD (Optimised
Crossports Design). Carefully designed shapes of the openings and their
optimal placement between stress lines guarantee efficient pressure
distribution in the canopy and its quick inflation. These openings are scaled
together with the ribs, so that their replicability is flawless and they do not
disturb the aerofoil in any way.
6

Another feature of the Orca XX is the Flexi-Egde
technology. The leading edge is closed to the airflow,
and its precise shape is kept with laminated cloth
reinforcements, incorporating synthetic rods. The rods
make the leading edge stiffer and smoother, bringing improvements in many
areas - from easier inflation, through stiffening the canopy in flight to
improved general airflow.
The wing tips additionally feature ACS (Auto Cleaning
Slots) – as the name suggests, these are dedicated
openings automatically removing dirt from inside the
canopy.
Careful selection of modern fabrics and design solutions brings about great
strength and durability of the Orca XX. All materials used come from marked
production batches, and each production step can be verified down to
identification of specific worker and controller.
Orca XX is manufactured under new technology, utilizing
precision of the laser cutter. All stages of production
process take place in Poland under strict supervision of
the designer himself, thus ensuring highest European
quality.
CLOTH
Orca XX is built with the best available cloth, guaranteeing good durability
with as low as possible weight. For that reason we have chosen textiles of
Porcher company, for years developing most modern paragliding materials.
The leading edge on the upper surface is made of Porcher Skytex Universal
2
E25 (38g/m ) cloth, with the rest of the canopy sporting Skytex Universal
2
E3W (32g/m ) due to great weight/resistance
ratio of this fabric. Both textiles are based on
nylon covered with outstanding impregnates,
introduced into mass production only after a
series of extensive laboratory and real flying tests.
Such covered fabric are not very stiff and - what's most important - have
increased tear, stretch and UV resistance. They are is not siliconised, so
minor repairs can be easily made with self-adhesive strips.
The ribs must be as rigid and stretch-resistant as possible. We found these
qualities in Skytex Hard with E29 impregnate (40g/m2), forming most main
ribs. Remaining ribs and supports are made of lighter, 32-gram variant of this
textile.
7

RIGGING
All suspension lines are sheathed by a coloured
polyester layer, which is covering a brownish Technora
core. Low number of lines required such composition in order to obtain high
strength and stretch-resistance of the lines.
The rigging system consists of individual lines looped and stitched at each
end.
The upper level lines start at the attachment points. Cascade-wise they are
joined to middle layer lines. These in turn connect by twos to main
suspension lines, which are attached to the risers with triangular quick links
(maillons). To prevent their slipping off, the lines are kept together with a
rubber 'O ring' (typically used as gasket). It is twisted in eight to stay in place.
All the maillons are made of corrosion resistant, polished
stainless steel, ensuring excellent strength and durability.
We use only certified maillons by Peguet company.
Stabilo lines run from the outer suspension points to the
maillons through consecutive cascades as well.
The same story goes for the steering lines. They run from the trailing edge
through several layers to the main steering lines, which are lead through the
pulleys connected to the rear risers and then fixed to the brake handles.
Steering lines do not carry any load.
Some of the steering lines of the upper level are additionally led through
rings sewn into the trailing edge, shortening it when the brake is applied. In
this way steering becomes lighter and more effective.
THE RISERS
For the Orca XX we have chosen four-way risers equipped with:
<ELR (Easy Launch Riser) system. This is a specially
marked A riser (red ribbon),
<trimmer with replaceable (in case of deterioration)
regulation strap, affecting the B, C and D risers
<(>>>deleted<<<)
For quick and easy recognition, some of the risers are
distinguished with coloured band as follows:
A - red (used for launching)
A' - red (used for big ears)
B - yellow (used for B-stall)
C - neoprene black
D - blue (needed to keep the glider down in strong wind – aborted
launch).
8

9
Main A row suspension lines connect to A and A' (both red) risers. B row and
stabilo lines go to B riser (yellow), C lines go to C riser (neoprene black) and
D lines to D riser (blue), together with steering lines (through appropriate
pulleys)
Brake handles are attached to the steering lines at optimal point,
guaranteeing safe and effective operation. It is marked black on the main
brake line and this setting should not be changed. Fixing brake handles
above that point causes permanent braking of the paraglider which can
easily lead to an accident. Overly long brake lines are not advised either, as
total lack of strain can prove dangerous in some situations.
Brake handles used in Orca XX besides its attractive, light design, feature:
<a swivel – preventing possible twisting of the steering line,
<soft neoprene cover,
<ACT (Adjustable Comfort Toggle), system with
adjustable loop size
3. Trimmers
Trimmer system consists of a trim shackles sewn into C and D risers, and
red regulation strap going through the shackles and fixed to risers with
rectangular connector link.
We have 3 main positions of the trimmers:
- full closed (slowest speed, minimum sink)
- neutral „0" (best take-off position)
- fully released (increased speed and sink)
During normal flight at neutral position all risers have equal length of 400
mm. Trim operation affects the B, C and D risers.
When trimmers are is fully opened, the D risers goes out to its maximum
possible length of 510 mm, while B and C proportionally less.
Make sure that both trim buckles are locked in the same position, otherwise
you will be constantly and unwillingly turning. It must be checked before
every launch!
Maximum speed is obtained when the trimmer tape is fully stretched.
TRIMMER OPERATION
The main goal of the trim is to adjust the paraglider speed to various loads,
depending on pilot and passenger weight (the weight range of a tandem
wing is greater than single-seater).

To sum it up:
<greater take-off weight – trimmer more closed,
<lesser take-off weight – trimmer more opened.
The other goal of the trimmer is adjusting the speed during flight, accordingly
to your needs and changing conditions.
Before the launch connect the risers to the tandem spreader bars with main
carabiners. Then have a check that the trim operation is not limited.
It is advised to set the trimmers at neutral “0” position for the launch, thus
improving canopy inflation. This position is also most universal to fly within
standard load of the paraglider.
To close the trim (and slow down) just pull the trim tab down. The shackle
will change its position and remain still in new place.
Completely closed trimmers can be used for thermalling, given that you do
not fly near maximum load. In turbulent air this could lead to a deflation or a
spin.
In order to open it (and fly faster) you should grab the shackle, push the
knob with your thumb and thus allow the trim to move up.
By releasing the trimmers you increase the airspeed. Such configuration is
especially needed when flying against strong headwind or seeking next
thermal.
Orca XX stays calm even at completely released trimmers and full speed.
Whenever you do adjust trim settings, always remember to do it
symmetrically.
4. Harnesses and spreader bars
When flying an Orca XX you can use any certified harnesses and spreader
bars that will make both pilot and passenger feel safe and comfortable.
Typical passenger harnesses have simple design, so as not to hinder the
pilots' movements. Harness for the pilot should be equipped with divided
seating and proper tandem rescue system. The spreader bars must allow
various hangpoint configurations, in order to compensate pilot and
passenger weight differences.
Please note that changing distance between seat plate and hangpoint
greatly influences position of the brake handles in relation to pilot's body.
Therefore you must always remember that the handling characteristics and
stall point can vary with different hangpoint configurations.
10

Tandem spreaders
Orca XX is sold with a pair of spreaders, equipped with a Big Ears lock.
CAUTION! Make sure that each of the spreaders was installed on its
dedicated side – the red ball locking the Big Ears should always be on the
outer side.
5. Flight
PRE-FLIGHT CHECK
A thorough pre-flight check is essential for any aircraft; the Orca XX is no
exception.
Having unpacked and laid out the paraglider, following checks must be made:
<canopy, lines and risers condition. Do not launch if any damage is
noticed,
<the paraglider should be arranged so that the centre section A-lines (of
golden risers) will strain earlier that the outer ones (A' - blue risers). This
ensures an easy and symmetrical launch,
<cells of the center section must be hadled with care, especially the
leading edge should stay taut and even,
<all lines and risers should be separated. Make sure they are not tangled
and pay special attention to the A-lines, which should run free from the A
(golden band) and A' risers (blue band) to the canopy,
<it is equally important to untangle the brake lines so that they will not
catch anything on the ground during launch. They must be firmly
attached to the brake handles and run freely through the pulleys to the
trailing edge,
<make sure the risers are not twisted,
<it is very important to check that no lines are looped around the canopy.
The so-called "line-over" may have disastrous consequences during
take off.
<remember to set the trimmers symmetrically
Always put on and fasten your helmet before clipping in to the harness.
Check quick links (maillons). They can unscrew, especially when the
wing is new.
Check main carabiners. They must be properly mounted, closed and
locked.
11

LAUNCH
Due to considerable passenger/pilot inertia, most tandem flights usually start
with a classic straightforward launch. The alpine (reverse) launch is
executed only when the wind speed makes normal start impossible.
For the launch neutral trimmer position is recommended.
Classic launch
Facing the wind, put the risers over your shoulders (with A risers on the top)
and clip into carabiners, connected with spreader bars. Lock the carabiners.
Grip the brake handles and A-risers (marked with red band), holding them at
the stitching, just under the quick-links. Spread your slightly bent hands out,
keeping them a bit down and back. All remaining risers should be placed
near your elbow joints.
Apply some tension to check if the A risers stay on top and the lines are not
tangled. Take a step back under the center wing, bow down a little and run
forward. After the initial inflation smoothly move the hands up and over your
head until the wing will be directly above you. Let the A risers loose and
check the wing. Pump out possible faults and keep the canopy straight
above you.
Possible side drift is corrected best by moving yourself under the canopy, as
long as the launch space permits. In order to keep the wing in the air the
suspension lines must stay taut all the time, so in light winds you will have to
run forward. With stronger winds you can control the wing while standing
still.
When leaving the ground apply some brakes, then release it after gaining
some height. Keep you hands relaxed.
Reverse launch:
After clipping the risers into carabiners as for the forward launch, turn back
to face the wing, moving one riser group over your head. As a consequence,
you will have the risers crossed.
Unclip the brake handles from rear risers and grip it outside of the risers
without crossing neither arms, nor lines. In this way you steer the left side
with you left hand and vice versa. Now take corresponding A risers on both
sides.
Make sure that the wing inflates symmetrical and the lines are not tangled.
Building up tension with a few steps back and simultaneously lifting the A
risers (without pulling them towards you) will make the paraglider rise. When
it arrives over your head, stabilize it with the brakes, check again if all lines
are clear and the cells inflated.
12

When turning into wind, remember to turn the right way (hint: always do it
the same direction) and keep the lines under load at all times. The turn itself
should be quick and smooth. While turning you have to release the brake
handles and grip them again facing forward. Last check of the wing & free
space to launch and off you go.
CAUTION: when deflating the canopy in strong winds (e. g. aborting a
launch), use the D risers, not the brakes. Using the brakes in strong wind
causes more lift, that eventually can lift the pilot up and drag him/her back.
TURNS
Orca XX is an agile wing, with smooth reactions to the steering inputs.
Handling is actually easy for such a big canopy, and forces grow
proportionally to position of the brakes. Adding some weight shift will make
the paraglider turn really quick and tight.
The combined technique (weight shifting and brake input) is by far the most
efficient method. Turn radius is determined by the amount of inside brake
used and weight shift. Additional application of a little outside brake after
initiating the turn with maximum weight shift increases efficiency and the
outboard wing's resistance to collapse (in turbulence, the edge of a thermal
etc).
In case of necessary turn in confined area at slow speed (e.g. slope
soaring), it is recommended to steer the decelerated canopy by loosening
the brake at the outside of the turn while applying a little more brake on the
inside.
NOTE: when entering a turbulent area you should brake a little, just to
put up the tension. It will allow you to react instantly in case of a
problem.
CAUTION: Too hard or too quick pulling of one brake can cause the
wing to enter a spin.
THERMALLING AND SOARING
When flying Orca XX, minimum sink is achieved with light pull on the brakes
(15 to 20 cm depending on total weight in flight) and closing the trimmers.
Just be careful with closing the trims when flying at low weights - it is not
advisable.
In turbulent conditions the canopy should be flown with a small amount of
brake applied. This improves overall stability by increasing the angle of
attack of the canopy. The canopy should neither rock back nor surge
forwards, but always stay above the pilot. In order to achieve it, the pilot
should accelerate the canopy by letting off the brakes when entering a
thermal (accordingly to its strength) and brake it on exiting. This is part of
13

basic active flying that can spare you many potential collapses.
When soaring the slope, minimum height of 50 m above the ground is
recommended for safety reasons. It is important to comply with air traffic
rules, especially when many pilots share airspace close to the hill. The
avoidance manoeuvres often happen to be impossible in such conditions.
LANDING
Considering safety of the pilot and the passenger, landing should be always
well planned. Last turn into the wind must be done with sufficient altitude.
Prior to landing you should build up speed, fully releasing the brakes, and
then flare out at 1 - 2 meters over ground. The glider may even climb again
for a while gaining some height, if too much brake is used.
The best trimmers position for the landing is to reset them at neutral ”0”.
Strong wind landings hardly require braking, if any at all! Use D-risers
(coloured blue) to deflate the canopy after landing. Using the brakes will
probably result in pilot (and passenger) being lifted and dragged backwards.
The final glide of the landing approach should be straight and smooth. Steep
or alternating turns can result in a dangerous pendulum effect near the
ground.
WINCHING AND MOTOPARAGLIDING
During tests, numerous flights were made with winch start and backpack
power units, as these are the only means to gain some height in flatlands.
Absolutely no reasons were found for not using Orca XX tandem in such
flights.
CAUTION!
During launch, especially with a winch or paramotor, always remember
to bring the wing fully over your head.
Orca XX aerofoil and its angle of attack were calculated create give
maximum lift coefficient with relatively high safety. As a result of its
thick aerofoil it can stay behind a pilot, if he neglects bringing it over
head.
AEROBATICS
Orca XX was not designed for doing aerobatics.
6. Rapid descents
BIG EARS
You can deflate the wing tips simultaneously pulling down the A' risers (red
band) by approximately 50 cm.
14

With big ears pulled the paraglider will fly straight, albeit with increased sink
(max 5 m/s). If you keep the risers in hands, the paraglider can be steered
with weightshifting.
Our new spreader bars are equipped with a locking system (Big Ears
Keeper), able to lock the pulled down line under the red ball placed on the
spreader. This allows to keep the Big Ears down as long you wish, with full
control of the paraglider via regular steering system. In order to use the Big
Ears lock it is enough to place the A’ riser line under the ball from the
outside. Then check carefully if the line is properly placed and will not slide
free by chance.
On releasing A' risers (or unlocking lines from red balls) in dynamic air the
canopy usually reinflates on its own. In case of necessity it can be assisted
by a long pump until the tips get clear.
WARNING! When flying with Big Ears pulled down avoid hard steering,
since the canopy in such configuration has shorter steering paths and
you can stall or spin it much easier than normally.
IMPORTANT!
Use the Ear lock with substantial altitude margin. If you have to reduce
your altitude shortly before landing, keep the ears by hand without
using the blocking ball.
SPIRAL
It is characterized by reaching the highest sink rates. Significant G-forces,
however, make it difficult to sustain a spiral dive for long, as it can place high
loads on the pilot and glider. Never do this manoeuvre in turbulence or at too
high bank angles. You have to watch constantly the situation, in order to
prevent your spiral from turning into a spiral dive (sink rate over 16 m/s).
If the pilot releases inner brake and the wing does not start slowing down, he
should assist this process with the outer brake.
NEVER DO BIG EARS IN A SPIRAL! Tests have proven that loads in
spiral dive can be even higher than those used in certification tests (i.e.
8 G). This can result in structural failure of the glider, as smaller
number of lines is taking these high loads.
B-STALL
To enter a B-stall you have to simultaneously pull both B-risers (yellow)
down by 10 - 20 cm. The wing collapses on its entire span along B-row, the
airflow over the top surface will break and the canopy projected surface will
be significantly reduced. Forward speed will die and you will be descending
almost vertically.
15

Further pulling of the B-risers is not advised, as the wing instability can grow.
This manoeuvre is rather hard to execute on the Orca XX due to great forces
required to pull in the B riser.
To exit B-stall the risers should be released in a smooth and decisive
manner.
After quick and symmetrical releasing B-lines the airflow reinstates and the wing
surges forward to return to normal flight.
If the canopy forms a horseshoe with the wingtips in front of you, gently apply
both brakes to recover.
CAUTION! See DEEP STALL
All rapid descent techniques should be drilled in smooth air and with
sufficient height only! Full stalls and spins are to be avoided as recovery
procedures, since irrespectively of paraglider type they may have
dangerous consequences!
BY FAR THE BEST TECHNIQUE IS WISE, CORRECT AND SAFE FLYING,
SO THAT YOU WILL NEVER HAVE TO DESCEND RAPIDLY!
7. Extreme flying manoeuvres
CAUTION! EXTREME FLYING MANOEUVRES SHOULD ONLY BE
CARRIED OUT DURING SAFETY TRAINING COURSE (INSTABILITY
TRAINING) UNDER PROPER GUIDANCE!
WHILE PROVOKING OR EXITING REAL SITUATIONS THERE IS A DANGER
THAT YOUR ACTIONS WILL PROVE TOO QUICK OR TOO STRONG, SO
YOU SHOULD ALWAYS EMPLOY GOOD JUDGMENT, STAY CALM AND
TAKE ONLY MEASURED ACTIONS.
Since all actions required to exit or prevent dangerous situations on Orca
XX are typical and pilots flying this wing should be properly qualified, we
are going to describe only the characteristic features of the Orca XX.
Description of standard dealing with extreme situations can be found in
textbooks.
SIDE COLLAPSE
May happen in strong turbulence. Usually Orca XX does not turn at all.
In case of collapses of some 50% pilot has a couple of seconds to react before
paraglider enters rotation.
A little countermeasure will be enough to keep it on course. Under normal
conditions Orca XX will reinflate instantly and spontaneously.
16

SPIN AND FULL STALL
Practically do not occur. It may happen only as a result of serious mistake or
intentional action. In normal flight braking up to the stall point requires much
force and its proximity cannot be overlooked.
Wing recovers spontaneously in initial phase of stall, otherwise use standard
procedures.
WING OVER
You make a wingover by executing a series of consecutive, alternating turns
with growing bank angle. Too much banking with some flaws in coordination
can evoke pretty dynamic collapse.
CAUTION: Steep turn with bank angle over 60 degrees is a prohibited
aerobatic manoeuvre!
FRONTAL COLLAPSE
Can happen in strong turbulence. Active piloting will usually prevent its
occurrence. Under normal conditions Orca XX reinflates instantly and
spontaneously. Applying some brakes in the right moment will greatly speed
up the recovery.
LINE OVER (CRAVATTE)
Not very likely when flying Orca XX. Use standard action, in case of any
doubts pilot should seriously consider throwing the rescue chute.
DEEP STALL
Under normal conditions does not occur.
If you want to prevent it, stick to a couple of rules:
<after B-stall, release the risers quick and even. Orca XX does not jump
forward excessively.
<prior to executing Big Ears you should fully open the trims. It will
increase the sink rate and safety margin, as big ears constitute an
aerodynamic brake with significant loss of speed.
If parachutal stall happens nevertheless, best solution is to push forward A
risers or pull them downward.
EMERGENCY STEERING
In case of malfunction rendering it impossible to control Dudek Orca XX with
brakes, you can safely steer and land using the D-risers (blue) or stabilo lines.
17

8. Canopy care
Proper maintenance of the paraglider will greatly enhance its durability.
FOLDING AND STORAGE
Orca2 features a number of recent technologies, like tensioning the leading
edge with a plastic string. That's why the paraglider should be folded with care
in order to keep it healthy during transport and storage.
Basic rules to be observed when folding:
1. We fold the canopy together on rib-to-rib, cell-to-cell basis (like a
harmonium). We don't break the wing in halves, taking the stabilizers towards
centre.
2. After creating a package along the maximum chord, we don't roll it, but fold
two to three times (depending on the chord length) from trailing to the leading
edge.
3. Leadin edge stays on top of the folded canopy.
4. Don’t pack too tightly.
Please note that frequent playing with your paraglider on a field or a small hill
will deteriorate it quickly due to its repeated rising, falling down and dragging
around.
A good precaution to avoid catching wet and/or UV is to use quickpack after
rigging up, when you have to wait in start line.
Never pack up or store the glider when wet. This shortens the life of the cloth.
Remember that wing gets wet even when laying on a green grass in full sun, as
the grass evaporate.
Leaving wet paraglider in a car heated by sun is absolutely unacceptable!
Effect of an oven occurs and as house tests of the wet fabric have shown,
colours can get unstable even at 50 grade Celsius. Guarantee claims
concerning colour loss and stains will not be accepted!
While drying, never expose your paraglider to direct sunlight.
Store the paraglider in a dry space, away from chemicals and UV exposure.
CLEANING
Clean the paraglider with water and a soft sponge. Do not use any chemicals or
spirit, as these can permanently damage the cloth.
REPAIRS
Repairs should only be carried out by the manufacturer, authorised distributor or
authorised workshops. It is acceptable to fix minor cloth damages with self-
adhesive patches included in package.
18

INSPECTIONS
Full inspection is recommended every 24 months, or 150 flight hours
(depending on what comes first) if not advised otherwise by the inspecting
person due to current paraglider condition.
Paragliders in commercial use (training and tandem flights) should be undergoing
Full Inspection every 12 months (excluding first 24-month period after purchase).
Technical inspection is carried out by the manufacturer or authorised person.
DETERIORATION: A FEW TIPS!
Orca XX is mainly made of NYLON, a cloth which, like any other synthetic
material, deteriorates through excessive UV rays. Hence it is recommended to
reduce UV exposure to a minimum by keeping the paraglider packed when not in
use. Even when packed in the bag, it should not remain in the sun for long.
Orca XX lines consist of Technora inner core with polyester sheath. Putting them
to excessive loads in flight should be avoided, as it can cause irreversible
damage.
Keep the paraglider clean, since getting the dust in lines and cloth will reduce
their durability.
Be careful to keep snow, sand or stones away from entering the cell openings:
their weight can slow down or even stall the glider, and sharp edges can damage
the cloth!
Prevent lines from catching anything as they can get overstretched or torn. Do
not step on the lines.
Uncontrolled strong wind takeoffs or landings can result in the leading edge of
the canopy hitting the ground with lots of energy, which may heavily damage the
ribs and surface material.
Knots can chafe the suspension and/or brake lines.
Check line lengths after tree or water landings, as they can stretch or shrink. The
lines should be measured with specialized equipment at the manufacturer or
authorised workshop.
After landing in water you should check the cloth as well, since the wave forces
can cause the canopy fabric to distort in specific areas.
When taking the wing out of water, always do this by the trailing edge, so that
water can flow out freely. After landing at sea rinse the paraglider with fresh
water. Since salt crystals can weaken the suspension lines even after rinsing in
fresh water, you should replace them with new ones immediately after contact
with salty water.
Every second year Orca XX should undergo inspection by the
manufacturer or authorised distributor (note that not all dealers are
equipped to do that).
