Please read this manual carefully before you start, this way you will get the most out of
yourglider,andenjoymanyniceflights.
Paragliding is a sport, which demands, besides the optimum equipment, a high degree
of attentiveness, good judgement, and theoretical knowledge. Paragliding can be a
dangerous sport, which may lead to injury and death.Avoid flying in strong turbulence,
strongwindsandespeciallyinthunderstormsandFoehnconditions.Thesecouldleadto

weather,windorterrain,don’ttakeoff.
Before delivery, as well as during production, each paraglider goes through a strict
visual inspection, and is test-flown by your dealer. Stamps on the placard, together with
a completed test-flight certificate, confirm this. Check that the paraglider has been test-
flownbeforeyourfirsttake-off.Ifithasnot,consultyourdealer.
If,after carefully reading this handbook, you still havequestions,telephone your dealer;

Warning and safety precautions
The buyer of this product accepts full responsibility for all risks associated with
paragliding inclusive of injury and death. Any inadequate use or misuse increases the
risks considerably. The buyer should be aware of the need to complete a paragliding
training course and should be in possession of a valid flying licence as required by the
relevantcountry.
Anychangesmadetothisparagliderinvalidatethecertificateofairworthiness.
The VELVIA must not be used:
- outside the certified weight range
- during rain or snow-fall
- in high or gusty winds
- in cloud and fog
- by pilots without sufficient knowledge or experience
The VELVIA is certified for solo flight.
Operating limits
TheVELVIAhasbeendevelopedforfoot-launch,andforsoloflights.
TheVELVIAhasbeentestedbyDHVtestpilotstoDHV1-2GHcategory.
The GH stands for 95% of all sitting harnesses in use. It simply means that a harness
with a chest-strap is needed. It also has been load and shock-tested and passed with a
load corresponding to 8 G of the maximum weight in flight 110 kg. Its flying test have
shown that the glider remains stable and controllable over a wide range of normal and
abnormal flight conditions. Nevertheless, turbulence and gusting winds can lead to a
partialorcompletecollapseofthecanopy.Thereforeneverflyinsuchconditions.

Construction
Trim
Safetyequipment
The VELVIA is a second rib diagonal-construction paraglider. Every second main rib is
attached to the lines and other ribs are attached at A, B and C-points thanks to the
diagonal segments. These segments do not lead to top surface of canopy but are
attached at 80% of rib's height. This technique was already used on the EDEN 1 and is
usedbymanyothermanufacturersintheindustry.
The glider is delivered with a standard set-up and its speed can reach 36 - 38 km/h
depending on the weight of the pilot. The brake-lines should always be adjusted so that
the first brake-lines just come under tension when the brake handles have been pulled
5-10cm.
The test results relate to this brake-line adjustment. In extreme situations other settings
may lead to the glider reacting differently. To be able at all times to react quickly enough
to possible problems; you should not let go of the brake handles during the flight (it may
bepossible toholdbothhandlesinonehand).Alterthelinelength tobringthehandlesto
asuitableheightwhenusingyourharness.
An optimal outfit should be a matter of course for every paraglider pilot. Always wear
stout footwear, a helmet, and gloves. Clothing should be warm and allow sufficient
freedom of movement. A rescue-system can be life-saving in case of an irremediable
disturbance of the canopy, collapse in the air or material failure, and is therefore
imperative.
NOTE!! If in doubt about the brake-line adjustment, it is preferable to leave them too
long,asanynecessaryshorteningcaneasilybe achieved by wrapping them round your
hand.

Speed system
To fly faster than trim speed the VELVIAis equipped with a foot operated original speed
system. When in use, it lowers the angle of attack. VELVIA is designed with a 4-riser
systemtofurtherimprovesafety.
VELVIA has a very wide speed range.The highly effective speed system of the VELVIA

Inadditionalto alltheusualpre-flight checks,pleasepayparticular attention totheitems
inthefollowingchecklist:
1. Inspection of canopy for tears or damage, especially the seams which join the ribs to
theupperandlowersurfaces,butalsotheareaof the attachment tapes and brake-line
connections.
2. Inspection of the attachment tapes for damage to the stitches. It is also important to
check the attachment tapes and brake-lines for tangles. The line lengths must be
checked after 50 hours flying time and whenever the flight behaviour of the glider
changes.
3. Inspection of the risers and maillons for faultless condition. Special inspection of the
maillonsfortracesofcorrosionunderthelines.
4. Inspection of the knotting of the steering handle to the brake-lines. The brake-lines
mustrunfreely.
5. Inspection of the harness. The harness must show no signs of wear or other damage.

6.Checkwhethertherescue-systemiscorrectlyinstalledandsecured.
7.Inspectionofthekarabiner.Inspectionoftheattachmentandsecuringofthekarabiner.
Find a suitable take-off spot, from which you can abort the take-off at any point. After
checking the glider, following the checklist, lay it out with the cell-openings upwards so
that the canopy forms the shape of a horseshoe. In a strong wind don't spread the
canopytoofar,sothatthereislessresistancewhenpullingup.
This is possible in almost all wind conditions except strong headwinds. It is essential to
standinlinewiththecanopy, especially when the glider has longer lines. Before take-off,
place yourself centrally at the gliders axis. Let the B C and D-risers fall into the crook of
your arm and pull the canopy dynamically up byA-risers. The stronger the headwind the
less run-up you need to pull the canopy up. As soon as the glider is above you, stop
pullingontheA-risers. Nowdoavisualcheck upwards, toseeifthecanopy is completely
open. Otherwise, abort the take-off. Now accelerate continuously until you lift off. In a
weak headwind it is easier to take-off if after reaching minimum flying speed you pull the
brakesslightly.Afterthetake-off,gentlyreleasethebrakesagain.

strong,takesome ofthepressureoutofthecanopybytakinginoneorboth ofthebrake-
lines(ortheC-risers).
Always fly with sufficient clearance from the terrain. The VELVIA glides best with open
brakes, descends best with lightly applied brakes. In turbulence fly with brakes lightly
applied to avoid canopy collapse. If the canopy pendulums forward, this should be
corrected by prompt braking. A pendulum movement of the canopy backwards is
correctedbylooseningthebrakesingoodtime.
Turnscanbeinitiatedusingthebrakesintwodifferentways.
The pilot pulls the brake on the side to which he wishes to turn. To minimise sinking, the
brakeontheoutsideofthecurveislightlyapplied.
The pilot pulls the brake on the side to which he wishes to turn and shift his weight to the
same side. Turns can also be flown with the harness alone, by shifting the weight to the
insideof thecurve.This weightshifthas agreatereffect,themoreloosely thechest-strap

steeringinnormalflight.
To avoid stressful situations in the approach to landing, it is important to initiate the
process at an adequate altitude. This leaves you enough time to observe and
appropriatelydealwithwinddirectionandanyotheraircraftinyourvicinity.
The final approach should generally be made into the wind and with fully released
brakes, in order to maintain maximum energy in the glider. If the air is turbulent, it is
better to land lightly braked to minimise the possibility of the canopy collapsing. In order
to land on your feet, rather than lying on your back, you will need to lean forward in the

In a light headwind pulling the brakes only lightly is enough to give a soft landing. In a
calm, or even tailwind, you must pull the brakes as abruptly as possible. This

EXTREME AND CRITICAL FLIGHT MANOEUVRES

9
Collapseofthecanopy
Remember this is a glider with unspectacular reactions to disturbances in the air.
Whenever in doubt, let up the brakes and let the glider fly. The glider has a high internal
pressure, resistance to tucking and very high degree of passive safety. It is
recommendedthatatthisstageyoualreadystarttopractisinganactiveflyingstyle.The
key to active piloting is keeping the glider above your head at all times. We recommend
in principle that you hold the brake handle in your hand whenever possible, or fly with
yourhandsthroughthebrakehandles,toallowyoutoreactimmediatelytoanypossible
disturbances.
Thisformofcollapseoccursmostfrequently,causedbyturbulence.
Pull the outermostA-line slowly down, until the edge of the canopy folds in. The canopy
collapsesfurthestif youpullA-riserviolentlydown.This causesupto70 %oftheleading
edgetocloseup,andresultsinthecanopygoingintoaspiraltowardsthecollapsedside.
If the harness is too loosely adjusted, in a more extreme collapse you will fall in the
direction of the folded-in side, thus unintentionally magnifying the canopy's tendency to
turn.
Recovery
BasicallytheVELVIAwillre-openbyitselffromclosuresofupto70%byturningof90°.
The time this takes, and the associated loss of height, can however be noticeably
reduced by appropriate action by the pilot. Apply opposite brakes on the un-collapsed
side, the outside of the curve, to stop the turning movement of the canopy. If you react
immediately, 30% brake on the open side shouldsufficetoholdthe canopy on a straight
course.
WARNING!! Ifyouflywithyourhandsthroughthe brakehandles,youmaylosevaluable

WARNING!! Especiallyinturbulence,youmust firststopthecanopyturning, beforeyou
pump out the collapsed side. When the canopy is stable again, open it by pulling the
brakelinesontheclosedside.Ifitistangled,pumpingthebrakelineshouldhelp.
WARNING!! Take care to avoid applying too much brake when pumping out the

WARNING!! In the case of a cravat which pumping of the brakes fails to release - apply
50% -70% brake on the open side of the canopy to stop rotation. Then pull the caught
line carefully to release it then pump out the affected side. Take care to avoid applying
too much brake when pumping out the deflation, as this may disrupt the airflow over the
canopyandleadtoastall.
NOTE!! Envy usually opens from frontal tuck by itself. If counter braking, be careful - do
not brake too much. You could cause glider to begin a full stall with following surge
forwards.
Symmetricalcollapse -"Big-Ears"
Frontaldeflation
Initiation
Whilstmaintainingcontactwiththebrakes,griptheoutermostAlineonbothsides..Work
yourhands as high as possible on these outermostA-lines, until you have enough to be
able to pull on them without pulling second A-lines as well. Pull outer A-lines down
simultaneously. The further you pull theA-lines, the greater the area of canopy that will
collapse(andthegreaterwillbethesinkrate).
Recovery
As soon as you release outer A-lines, the VELVIA will open slowly.(The recovery
depends on pilot's weight.) You can speed up its opening by light braking. If in extreme
casesthelinesgettangled,pumping(pullingrepeatedly)thebrakelinesshouldhelp.
If you feel strong turbulence coming, first step off the speedbar. Sometimes you may
havetopullbothbrakestoavoidadeflation.
Initiation
Hold the brake handles in your hands and grip A-risers at the level of connection with
lines. Now pull down far enough to make the whole leading edge fall in (the further you
pull,themoreareafoldsin).
Recovery
As soon as you release the A-risers, the VELVIA opens by itself and the glider will
recoverwitha smallsurge.You canspeedupthisprocess bylightbraking.If theA-risers

Stalls
Turbulence or rapid braking can lead to a pendulum effect, and thus to changes in the
angle of attack. In extreme cases this can make the airflow break away from the upper
surfaceofthecanopyevenwithoutthebrakesbeingactivated.
Initiation
Pull the brakes slowly down until you have no more forward speed. The canopy now
losesinternalpressureandthelowersurface pushes further and further up between the
suspensionpoints.The loss of internal pressure is greater the longer thegliderisheldin
thissituation.Duringtheparachutalstallthecanopyalwaysremainsopen.
You will probably have to feel for the right brake position at first. If you apply too much
brake, the canopy falls away backwards and the glider finds itself on the brink of a full
stall.Loosenthebrakelinesimmediately,untilthecanopyisoncemoreaboveyou.Ifyou
hesitatetoolong,thecanopywillsurgeforwards.
Recovery
Assoon asyoureleaseboth brakes,symmetrically,thegliderwill independentlyrecover
fromtheparachutalstall.
Initiation
Put your hands through the brake handles and grip the B-risers at the height of
connection with lines. Now pull the B-risers slowly down, until the canopy folds (parallel
to its long axis). The glider will now stabilise itself and sink rapidly, with virtually no
forwardspeed.KeepholdoftheB-risersthroughoutthemanoeuvre.
WARNING!! All canopies need some time after a stall (in extreme cases a couple of
seconds) before the airflow builds up again. You should therefore carry out all
manoeuvresinvolvingstallsatanadequateheight,asitwilltakeacertainamountoftime

WARNING!! In a parachutal stall, asymmetrical application of the brakes can lead to a
spin. If you must land from a parachutal stall, on no account apply the brakes very close
totheground,asareductioninareaincreasesthedescentrate.

go of the B-risers, as this can cause overloading. As soon as the risers have been
released,theVELVIAwill usually fly normally of its own accord. Otherwise you have two
possibilities:
1.PulltheA-risers,untilthecanopyregainsforwardspeed. Don'tpulltoofar,
orafrontaltuckwilldevelop.
2. Pull the brake lines until the canopy wants to fall backwards, and then instantly open
both brakes symmetrically. As a result the canopy will shoot forwards, thus regaining
forwardspeed.

with caution and lesser sinkrates to get a feel for the gliders behaviour. A pilot who is
dehydrated or not accustomed to spiralling can lose consciousness in a steep spiral
dive!
Spiraldive
14
Fly as far as possible from steep rises, to give yourself space to lose height.
Sink rate approximately 2-4 m/sec
Sink rate approximately 4-6 m/sec
This allows rapid descent without stalling. Sink rate, depending on pilot, 5-15 m/sec
Sink rate approximately 5-10 m/sec
- End the stall with sufficient time for the airflow to re-establish itself.
In principle, always fly in such a way that you do not need to lose height in a hurry.
The VELVIA is produced from the best materials (see Material Description). The glider
mustbechecked asaminimum,everyyearor after 100 flying hours. Do not step on the
lines. Although the lines were tested with „DHV-bend test“ they can be damaged if
steppedonwhilstonahardsurface,oriftheycomeintocontactwithsharpobjects.
If this happends contact your dealer for replacement lines. The lines must be checked
afterevery50hoursflyingtimeandwhenevertheflightbehaviourchanges.Consultyour
dealer or MAC ltd. Tears in the canopy must be professionally sewn.Adhesive patches
areonlyadequateforveryminordamage.Theglidermustalways bekeptcoolanddry.If
possible it should be stored lightly folded in a well-ventilated place. Protect the glider
from dampness and sunlight. Exposure to UV degrades the fabric. A damp or wet
canopy must be air-dried in a shady place. Do not expose the glider to temperatures of
greater than 50 degrees C, as this can cause softening and shrinking of the attachment
tapes. Clean the canopy only with warm water or a dilute soap solution. Do not use
solvents.

Theporosityshouldbecheckedwithaporositymeter(JDC).Comparetheresultantdata
withtheproducer'smanual.
Porosity measures should be taken on at least three points of both the top and bottom
surface. The first point should be placed 20-30 cm from leading edge in the middle of
canopy.Secondandthird pointsareplacedleft andrightfromfirst measure pointat25%
ofthespan. Oneadditionalmeasurement shouldbemadeon thetopsurfaceof thewing
tip.
The identified time should be higher than 30 second (JDC). In the event of the result
beinglessthan30seconds,theresultofthecheckisafail.
The check of canopy strength should be made with a Bettsometer (B.M.A.A approved
Patent No. GB 2270768 Clive Betts Sales). On the top and bottom surfaces make small
holeswithaneedleattheAlineattachmentpoints.Theexactverificationshouldbemade
inaccordancewiththeBettsometerusermanual.
Line strengths should be as specified in accordance with the DHV requirements. One
