Diva-manual-EN-1-0 April 2017
TheDIVAisatwo-linercompetitionparaglidersuitableforveryadvancedpilotsofferingahighlevelofperformance
combinedwithspeed,whichmakethiswingcompetitivebutrequiringahighlevelofpilotskill.
Theuseofthisgliderislimitedtonon-aerobaticmanoeuvres.
Thisparaglidermustnot:
1. Beownoutsidethecertiedweightrange
2. Haveitstrimspeedadjustedbychangingthelengthofrisersorlines
3. Beowninrainorsnow
4. Betowedwithatow-linetensioninexcessof200kg
Itisyourdealer´sresponsibilitytotestytheparagliderbeforeyoureceiveit.Thetestightrecordofthisisinthe
ServiveBooklettowardstheendofthismanual.Pleasebesurethatthishasbeencompletedbyyourdealer.Failure
totestyanewparaglidermayinvalidateanywarranty.

3. Preparation
1. Selectasuitabletake-offareadeterminedbywindandterrain,clearofanyobstaclesthatmaycatchinthe
linesordamagethecanopy.
2. Ifyourparagliderhasbeencorrectlypacked,youshouldtakeittothetopofthetake-offarea,andallowthe
rolledcanopytounrollitselfdownthehill(ifonaslope).Thisshouldleavetheparagliderwiththebottom
surfacefacingupwards,theopeningsatthedownwindendofthetake-offarea,andtheharnessatthetrailing
edgeattheupwindside.
3. Unrollthecanopytoeachsidesothattheleadingedgeopeningsformasemicircularshape,withthetrailing
edgedrawntogetheratthecentreofthearc.Theharnessshouldbedrawnawayfromthecanopyuntilthe
suspensionlinesarejusttight.

4. Pre-ight Inspection
TheDIVAisdesignedtobeassimpleaspossibletoinspectandmaintainbutathoroughpre-ightprocedureis
mandatoryonallaircraft.Thefollowingpre-ightinspectionprocedureshouldbecarriedoutbeforeeachight.
1. Whilstopeningouttheparagliderchecktheoutsideofthecanopyforanytearswhereyourparaglidermay
havebeencaughtonasharpobjectorevenhavebeendamagedwhilstinitsbag.
2. Checkthatthelinesarenottwistedorknotted.Dividethesuspensionlinesintosixgroups,eachgroup
comingfromoneriser.Bystartingfromtheharnessandrunningtowardsthecanopyremoveanytanglesor
twistsinthelines.Partiallyinatingthecanopyinthewindwillhelptosortoutthelines.
3. Itisparticularlyimportantthatthebrakesareclearandfreetomove.Checktheknotwhichattachesthe
brakehandlestothebrakelines.Severalknotsshouldbeusedhereorthelooseendsmaygetentangledin
thebrakepulleys.Bothbrakesshouldbethesamelengthandthiscanbecheckedbyaskinganassistantto
holdtheupperendofthebrakelinestogetherwhilstthepilotholdsthebrakehandles.Thebrakelinesshould
bejustslackwiththewinginatedwhenthebrakesarenotapplied.Aftercheckingthebrakelineslaythem
ontheground.
4. Alwayscheckthebucklesandattachmentsontheharness.Ensurethetwomainattachmentmaillons/
karabinersfromtheharnesstothemainrisers,andthesixshackleswhichattachtheriserstothelines,are
tightlydoneup.
5. Beforestrappingintotheharness,thepilotshouldbewearingagoodcrashhelmet.Putontheharness
ensuringallthebucklesaresecureandproperlyadjustedforcomfort.
Yourparagliderisnowreadyforight.

5. Flight Characteristics
ThismanualisnotintendedasaninstructionbookonhowtoytheDIVA.Youshouldbeanexperiencedpilot,but
thefollowingcommentsdescribehowtogetthebestfromyourDIVA.
Weight range
EachsizeoftheDIVAiscertiedforacertainweightrange.Theweightreferstothe‘overalltake-offweight’.This
meanstheweightofthepilot,theglider,theharnessandallotherequipmentcarriedwithyouinight.
WerecommendtheDIVAisowninthemiddleoftheweightrange.
IfyouytheDIVAinthelowerhalfoftheweightrange,theturningagilitydecreasesandthegliderwillbemore
damped.Instrongturbulencethewingtendstodeformandtocollapseslightlymorethanwithahigherwingloading.
IfyoumainlyyinweakconditionsyoushouldconsideryingtheDIVAtowardsthelowerendoftheweightrange.
IfyouytheDIVAintheupperhalfoftheweightrange,theagilityandthestabilityinturbulencewillincrease.Also
thespeedwillincreaseslightly.Theself-dampingwilldecreaseinturns,aswellasaftercollapses,soifyouyin
bumpyconditionsandyouwantadynamicightcharacteristicyoushouldgoforthetopoftheweightrange.
Active Piloting
Activepilotingisatoolthatwillhelpanypilotywithgreatersafetyandenjoyment.Itmeansyinginempathywith
yourparaglider,notonlyguidingthegliderthroughtheairbutalsobeingawareoffeedbackfromthewing,especially
inthermalsandturbulence.Iftheairissmooththefeedbackcanbeminimalbutinturbulencefeedbackiscontinuous
andneedstobeconstantlyassessedbythepilot.Suchreactionsbecomeinstinctiveingoodpilots.

Inordertogetthebestperformancefromthewing,thepilotshouldtrytocontrolitthoughsmallbrakeinputsand
weight-shift,ratherthanconstantlybeingpresentonthebrakes.Asmallmovementearlyismoreefcientthana
bigbrakemovementlatertocontrolthewing.Themoreyoulettheglideryattrimspeed,thebetterperformance
youwillgetoutofit.Theobjectiveofactivepilotingistogettheglidertoysmoothlythroughtheairwithastable
positionabovethehead,andcontrolledangleofincidence.Flyingactivelyincreasesyoursafetymargin.
Harness
TheDIVAistestedwitha‘GH’(withoutdiagonalbracing)typeharness.TheGHcategoryincludesweight-shift
harnessesaswellasABSstyle(semistable)harnesses.
Approved harness dimensions
ThisgliderhasbeentestedwithaharnessthatcomplieswiththeENstandardharnessdimensions.
Theseare:
Seatboardwidth:42cm.Thehorizontaldistancebetweentheattachmentpointsoftheparagliderrisers(measured
fromthecentrelineofthekarabiners)mustbe:
• Upto50kg=38cm
• 50-80kg=42cm
• 80kgormore=46cm
Take-off
ThebestinationtechniqueistoholdoneA-riserineachhand.
Forward Launch
TakeanA-riserineachhand.TheA-risersaremarkedwithredclothtomakethemeasytond.Innilorverylight

wind,standwithalltheAlinestautbehindyou,thentakeoneortwostepsback(donotwalkallthewaybackto
thecanopy)andbeginyourlaunchrunpullinggentlyandsmoothlyontheA-risers.Assoonasthecanopystartsto
riseoffthegroundstoppullingsohardontheA-risersbutpullalltherisersevenlythroughtheharness.Maintaining
gentlepressureontheA-risersalwayshelpsinverycalmconditions.Haveyourhandsreadytoslowupthecanopy
withthebrakesifitstartstoacceleratepastyou.
Reverse Launch
Inwindsover10km/hitisrecommendedtodoareverselaunchandinatethecanopywhilstfacingitusingthe
A-risers,withoutthe‘BabyA-risers,’topreventthegliderfrominatingthewingtipsrst.Releasingpressureonthe
A-riserswhenthecanopyisatabout45°willhelptoavoidovershooting.Thestrongerthewindandthegreaterthe
pressureontheA-risers,themorequicklythecanopywillrise.
Turning
TheDIVAdoesnotrequireastrong-handedapproachtomanoeuvring.Forafastturnsmoothlyapplythebrakeon
thesidetowhichtheturnisintended.Thespeedwithwhichthebrakeisappliedisveryimportant.Ifabrakeisapplied
fairlyquicklythecanopywilldoafasterbankingturn,butcaremustbetakennottobanktooseverely.Toattainamore
efcientturnatminimumsink,applysomebraketotheoutsidewingtoslowtheturnandpreventexcessivebanking.
TheDIVAiesverywelllikethis,butcaremustbetakennottoover-applythebrakesasaspincouldresult,even
thoughtheDIVAhasaverylowspintendency.TheDIVAwillturnfarmoreefcientlyifthepilotweight-shiftsintothe
turnintheharness.Rememberthatviolentbrakeapplicationisdangerousandshouldalwaysbeavoided.
Straight Flight
TheDIVAwillysmoothlyinastraightlinewithoutanyinputfromthepilot.Thetrimspeedshowninthespecstable
insection8isachievedwhenthegliderisownatthemaximumweightwithouttheaccelerator.Thetopspeedis
achievedatmax.weightwithfullspeedbarapplied.

Thermalling
ToattainthebestclimbratetheDIVAshouldbethermalledusingamildturn,asdescribedabove,keepingthewing´s
bankingtoaminimum.Instrongthermalsatighterbankingturncanbeusedtostayclosertothethermal´score.
Rememberthatweight-shiftingintheharnesswillmaketheturnmoreefcientandreducetheamountofbrakerequired.
Caremustbetakennottoapplysomuchbrakeastostall.Thisiseasytoavoidasthebrakepressureincreasesgreatlyas
youapproachthestallpoint.Onlyynearthestallpointifyouhaveenoughheighttorecover(atleast100mabovethe
ground).
Big Ears
The‘babyA-riser’allowstheDIVAtobe‘bigeared’simplyandeasily.Thisallowsthepilottodescendquickly
withoutsubstantiallyreducingtheforwardspeedofthecanopy(asisthecasewithB-lining).Toengagebigears
thepilotwillneedtoleanforwardintheharnessandgraspthebigearsrisers(oneineachhand)atthemaillons,
keepingholdofbothbrakehandlesifpossible.Pulltherisersoutanddownatleast30cmsoastocollapsethe
tipsoftheglider.ItisveryimportantthattheotherA-linesarenotaffectedwhenyoudothisasitcouldcausethe
leadingedgetocollapse.Steeringispossiblebyweight-shiftingwithbigearsin.Ifthebigearsdonotcomeout
quicklyontheirown,apumponthebrakeswillspeedthingsup.
Beforeusingthebigearsfacilityinearnestitisessentialtopractisebeforehandwithplentyofgroundclearancein
casealeadingedgecollapseoccurs.Alwayskeepholdofbothbrakesinordertoretaincontrol.Puttingyourhands
throughthebrakehandlessotheyremainonyourwristsisagoodmethodofdoingthis.
Spiral Dive
Anormalturncanbeconvertedintoastrongspiraldivebycontinuingtoapplyonebrake.Thebankangleandspeed
oftheturnwillincreaseasthedownwardspiraliscontinued.Becarefultoenterthespiralgraduallyastooquicka

brakeapplicationcancauseaspinoranover-the-nosespiral.
Theover-the-nosespiralisaspecialtypeofspiraldivewherethegliderpointsalmostdirectlyattheground.Itwill
enterthisifyoumakeasuddenbrakeapplicationduringthespiralentrysothattheglideryawsaround.Thenoseof
thegliderendsuppointingattheground,afterwhichitpicksupspeedveryquickly.Thistechniqueisverysimilarto
SATentrytechnique,andliketheSATitisanaerobaticmanoeuvre,whichisoutsidethenormalsafeightenvelope.
Pleasedonotpractisethesemanoeuvresastheycanbedangerous.Careshouldbetakenwhenexitingfromany
spiraldive.Topulloutofasteepspiraldive,releasetheappliedbrakegraduallyorapplyoppositebrakegradually.A
sharpreleaseofthebrakecancausetheglidertosurgeanddiveasthewingconvertsspeedtolift.Alwaysbeready
todampoutanypotentialdivewiththebrakes.Alsobereadytoencounterturbulencewhenyouexitfromaspiral
becauseyoumayythoughyourownwaketurbulence,whichcancauseacollapse.
CAUTION:SPIRALDIVESCANCAUSELOSSOFORIENTATION(blackout)ANDSOMETIMEISNEEDEDTOEXIT
THISMANOEUVRE.THISMANOEUVREMUSTBEEXITEDINTIMEANDWITHSUFFICIENTHEIGHT!
Speed System
TheDIVAissoldwithacceleratorrisersandaspeedstirrupasstandardbutcanbeownwithoutthespeedstirrup
attached.Launchingandgeneralyingisnormallydonewithoutusingtheaccelerator.Theacceleratorbarshouldbe
usedwhenhigherspeedisimportant.Glideangleisnotasgoodinthisformat,soitisnotnecessarilythebestway
toraceinthermicconditionsandthecanopyisslightlymoresusceptibletodeations.Usingthestirrupcanrequire
someeffortandthepilot´sbalanceintheharnesscanbeaffected.Itmaybenecessarytomakesomeadjustmentsto
theharness.Werecommendyouonlyyinconditionswhereyoucanmoveforwardsintowindwiththeriserslevel,
sothatyouhavetheextraairspeedinreserveshouldyouneedit.
ToyatmaximumspeedthestirrupshouldbeappliedgraduallyuntiltheupperpulleyontheAriserbuttsagainst
thesecondpulley.Theacceleratorsystemisdesignedtogivemaximumspeedwhenthepulleysoftheaccelerator
toucheachother.Pleasedonotgobeyondthispointbyusingexcessiveforcetoattempttomaketheglidergo

fasterasthismayresultintheglidercollapsing.
IMPORTANT:
1. Practiseusingthespeedsysteminnormalying.
2. Becarefulyingfastinroughorturbulentconditionsasdeationsaremorelikelytooccuratspeed.Thespeed
increaseisachievedbyreducingtheangleofattack,sothecanopyhasslightlymorecollapsetendency.
3. Rememberthatglidedeterioratesathigherspeeds.Bestglidesareachievedwhentherisersarelevelandthe
brakesareoff.
Checkthecomponentpartsregularlyforwearandtear,andensurethatthesystemalwaysworkssmoothly.
Landing
LandingtheDIVAisverystraightforward.Flareinthenormalwayfromanaltitudeofaround2mwhenlandinginlight
winds.Itmaysometimeshelptotakewrapsonthebrakestomakethearemoreeffective.
Strong-windlandingsrequireadifferenttechnique.Ifyouusethebrakestoareinastrongwindtheglidertendsto
convertthistoheight,whichcanbaaproblem.Thebestmethodistotakeholdoftherear-risersatthemaillonsjust
beforelanding,andcollapsethecanopyusingthesewhenyouhavelanded.Thegliderwillcollapseveryquicklyusing
thismethod.Theglidercanalsobesteeredusingtherear-risersbutbecarefulnottocauseaprematurestall.
Afterlanding,theB-riserscanalsobeusedtocollapsethecanopy,althoughitismoredifculttocontrolthe
collapsedcanopyonthegroundusingthismethod.

6.RecoveryTechniques
Stalls
Stallsaredangerousandshouldnotbepractisedinthecourseofnormalying.Stallsarecausedthroughyingtooslowly.
Airspeedislostasbrakepressureincreasesandasthecanopyapproachesthestallpointitwillstarttodescendverticallyand
nallybegintocollapse.Shouldthisoccuritisimportantthatthepilotreleasesthebrakesatthecorrectmoment.Thebrakes
shouldneverbereleasedwhenthewinghasfallenbehindthepilot;thebrakesshouldbereleasedfairlyslowly,toprevent
theforwarddiveofthecanopyfrombeingtoostrong.Apre-releaseofthebrakeandthereconstructionofthefullspan
isrecommendedtoavoidthetipsgettingcravattedduringtherecovery.AllpilotswhoytheDIVAareadvisedneverto
attemptthismanoeuvreunlessunderSIVinstruction.Thismanualisnotintendedtogiveinstructioninthisoranyotherarea.
Deep Stall (or Parachutal Stall)
TheDIVAhasbeendesignedsothatitwillnoteasilyremaininadeepstall.However,ifitisincorrectlyriggedorits
yingcharacteristicshavebeenadverselyaffectedbysomeothercause,itispossiblethatitcouldenterthissituation.
Intheinterestsofsafetyallpilotsshouldbeawareofthisproblem,andknowhowtorecoverfromit.Themost
commonwaytoenterdeepstallisfromayingtooslowly,fromaB-linestallorevenfrombigears.
Whenindeepstallthepilotwillnoticethefollowing:
1. Verylowairspeed.

3. Theparagliderappearsquitewellinatedbutdoesnothavefullinternalpressure.Itlooksandfeelsabitlimp.
Recoveryfromdeepstallisquitesimple:Thenormalmethodistosimplyinitiateamildturn.Asthecanopystartsto
turnitwillautomaticallychangetonormalight,butitisveryimportantnottoturntoofastasthiscouldinduceaspin.

6.RecoveryTechniques
ThesecondmethodistopullgentlyontheA-risers.Thishelpstheairowtore-attachtotheleadingedge,butbe
carefulnottopulldowntoohardasthiswillinduceafrontcollapse.
Ifthedeepstallisparticularlystubbornandthepreviousmethodsdonotworkthenafullstallwillsolvetheproblem.
Todothisapplybothbrakesagainfairlyquickly,asiftodoastrongstall,thenimmediatelyreleasebothbrakesand
dampouttheforwardsurgeinthenormalway.Thecanopywillswingbehindyouthenautomaticallyreinateandsurge
forwardinfrontofyoubeforereturningtonormalight.Itisthesurgeforwardthatexitsthecanopyfromdeepstall.
Spins
Spinsaredangerousandshouldnotbepractisedinthecourseofnormalying.Spinsoccurwhenthepilottriesto
turntoofast.Inaspinthepilot,linesandcanopybasicallystayverticalandrotatearoundaverticalaxis.TheDIVAwill
resistspinning,butifaspinisinadvertentlyinducedthepilotshouldreleasethebrakepressurebutalwaysbeready
todampoutanydiveasthegliderexitsthespin.Ifthepilotdoesnotdampthediveonexitingthespintheglider
mayhaveanasymmetricdeation.
Symmetric Front Collapse
Itispossiblethatturbulencecancausethefrontofthewingtosymmetricallycollapse,thoughactivepilotingcan
largelypreventthisfromoccurringaccidentally.ApilotcanreproducetheeffectbytakingholdofboththeA-risers
andpullingdownsharplyonthem.TheDIVAwillautomaticallyrecoveronitsownfromthissituationinaround3
seconds.Duringthisrecoveryperioditisadvisablenottoapplythebrakesasthiscouldstallthewing.
Asymmetric Front Collapse
TheDIVAisveryresistanttodeations;howeverifthecanopycollapsesononesideduetoturbulence,thepilotshouldrst
ofallcontrolthedirectionofightbycounteringontheoppositebrake.Mostnormalcollapseswillimmediatelyreinateon
theirownandyouwillhardlyhavetimetoreactbeforethewingreinatesautomatically.Theactofcontrollingthedirection

willtendtoreinatethewing.However,withmorepersistentcollapsesitmaybenecessarytopumpthebrakeonthe
collapsedwingusingalong,strong,smoothandrmaction.Normallyoneortwopumpsofaround80cmwillbesufcient.
Eachpumpshouldbeappliedinaboutonesecondandsmoothlyreleased.Inseverecasesitcanbemoreeffectivetopump
bothbrakestogethertogetthecanopytoreinate.Becarefulnottostallthewingcompletelyifthistechniqueisused.
Releasing a trapped tip (cravat)
OntheDIVAitshouldbedifculttotrapthetipsothatitwillnotcomeoutquickly.However,followingaverysevere
deationanycanopycouldbecometiedupinitsownlines.Ifthisoccursthenrstofallusethestandardmethodof
recoveryfromatipdeationasdescribedinAsymmetricFrontCollapseabove.Ifthecanopystilldoesnotrecover
thenpulltherearriserstohelpthecanopytoreinate.Pullingthestabilolineisalsoagoodwaytoremovecravats,
butremembertocontrolyourightdirectionasyournumber-onepriority.Ifyouareverylowthenitismuchmore
importanttosteerthecanopyintoasafelandingplaceoreventhrowyourreserve.
NOTE:TestpilotshavetestedtheDIVAwellbeyondthenormalightenvelope,butsuchtestsarecarriedoutin
averyprecisemannerbytrainedtestpilotswithaback-upparachute,andoverwater.Stallsandspinsonany
paraglidersaredangerousmanoeuvresandarenotrecommended.

Storage & Care
Ifyouhavetopackyourcanopyawaywet,donotleaveitformorethanafewhoursinthatcondition.Assoonas
possibledryitout,butdonotusedirectheatsourcesasitisinammable!
Alwaysstorethecanopyinadry,warmplace.Ideallythisshouldbeinthetemperaturerangeof5to13degrees
centigrade.
Neverletyourcanopyfreeze,particularlyifitisdamp.
Thehigh-qualitynylonyourparagliderismadefrom,istreatedagainsttheeffectsofultravioletradiation.However,
UVexposurewillstillweakenthefabricandprolongedexposuretoharshsunlightcanseverelycompromisethe
safetyofyourcanopy.Thereforeonceyouhavenishedying,putyourwingaway.Donotleaveitoutinstrong
sunshineunnecessarily.
Donottreatyourcanopywithchemicalcleanersorsolvents.Ifyoumustwashthefabric,usewarmwaterandalittle
soap.Ifyourcanopygetswetinseawater,washitwithwarmwaterandcarefullydryit.
Smalltearsinthetoporbottomsurface(notnormallytheribs)ofacanopycanberepairedwithapatchofself-
adhesiveripstopnylon.Tearsnolongerthan100mmcanberepairedinthiswayprovidingtheyarenotinahigh-
