1. Selectasuitabletakeoff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takeoff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takeoff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asthecentreofthearch.Theharnessshouldbedrawnawayfromthecanopyuntilthe
suspensionlinesarejusttight.

3 Pre-ight Inspection
TheDUAL/DUALLITE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:
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.
1. 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.
2. 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theymaygetentangledinthebrake
pulleys.Bothbrakesshouldbethesamelengthandthiscanbecheckedbyanassistantholding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.
3. 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
4. Beforethepilotandpassengerareattachedtotheirharnesses,bothshouldbewearingacertiedhelmet.Put
ontheharnessensuringallthebucklesaresecureandcomfortablyadjusted.
Yourparagliderisnowreadyforight.

4 Flight Characteristics
ThismanualisnotintendedasaninstructionbookonhowtoytheDUAL/DUALLITE.Youshouldbeaqualied
pilotorundersuitablesupervision,butthefollowingcommentsdescribehowtogetthebestfromyourDUAL.
Weight range
TheDUAL/DUALLITEiscertiedforaverylargeweightrange.Theglideriesbestintherangeof160-200kg,
thoughgenerallyitisnotsensitivetoweightdifferences,retainingniceyingcharacteristicsthroughoutthewholeof
thecertiedrange.Theweightreferstotheoveralltakeoffweight,whichmeanstheweightofthepilot,theglider,the
harnessandallotherequipmentcarriedwithyouinight.
IfyouytheDUAL/DUALLITEinthelowerhalfofitsweightrange,itwillbemoredampedandslightlylessagile.
Instrongturbulenceitwillhaveaslightlygreatertendencytodeformorcollapsethanifitwasmoreheavily-loaded.
IfyoumainlyyinweakconditionsyoushouldconsideryingtheDUAL/DUALLITEatthelowerendoftheweight
range.
IfyouytheDUAL/DUALLITEintheupperhalfoftheweightrangeitwillbemoreagile,morestableinturbulence
andslightlyfaster.Ifyouyinbumpyconditionsoryoupreferadynamicwing,youshouldaimtobenearerthetop
oftheweightrange.
Active Piloting
EventhoughtheDUAL/DUALLITEisdesignedasaneasytandemglider,‘activepiloting’isatoolthatwillhelpyouywith
greatersafetyandenjoyment.Activepilotingisyinginempathywithyourparaglider.Thismeans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through

thebrakesandtheharness.Suchreactionsareinstinctiveingoodpilots.Maintainingcontactwiththegliderthroughpressure
onthebrakesisessentialandallowsthepilottofeelthelossofinternalpressure,whichoftenprecedesacollapse.TheDUAL
/DUALLITEishighlyresistanttocollapsewithoutanypilotactionatall,butlearninghowtoyactivelywillincreasethis
safetymarginevenfurther.
Harness
TheDUAL/DUALLITE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.
Takeoff
TheDUAL/DUALLITEiseasytoinateinlightorstrongerwindsandwillquicklyriseoverheadtotheyingposition.
ThebestinationtechniqueistoholdoneAriserineachhand.Itisamatterofpersonalpreferenceifthepilotprefers
totakethebigearsriseraswellasthemainAriser.Bothtechniquesworkwell.
Nil Wind
InationisbestdonebytakingbothoftheArisersineachhand.TheArisersaremarkedwithredclothtomakethem
easier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10km/hitisprobablybetter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.TheDUAL/DUALLITEhaslittletendency
toovershootbut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DUAL/DUALLITEdoesnotrequireastrong-handedapproachtomanoeuvering.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DUAL/DUAL
LITEiesverywelllikethis,butcaremustbetakennottoover-applythebrakesasaspincouldresult,althoughtheDUAL/
DUALLITEhasaverylowspintendency.TheDUAL/DUALLITE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DUAL/DUALLITEwillysmoothlyinastraightlinewithoutanyinputfromthepilot..
Thermalling
ToattainthebestclimbratetheDUAL/DUALLITE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howeververy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.
Wing Tip Area Reduction (Big Ears)
The‘babyAriser’allowstheDUAL/DUALLITEtobe‘bigeared’simplyandeasily.Itisrecommendednottolandin

bigearsandtoexitfrombigearswithsufcientheight.
Thebigearfacilitydoesnotallowyoutoyinstrongerwinds,butenables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maillon,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practice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.
B-Line Stall
ItisverydifculttomakeaB-linestallontheDUAL/DUALLITEduetothehighloadontheBrisers.Itishowever
possibleifthepilotisheavierthanthepassenger.Thisisafastdescentmethodandisausefulemergencyprocedure.
Withbothhandsthroughthebrakehandles,thepilottakesholdofthetopoftheBrisers,oneineachhand,and
pullsthemdownbyaround50cm.Thiswillstallthecanopyanditsforwardspeedwilldroptozero.Makesure
youhaveplentyofgroundclearancebecausethedescentratecanbeover10m/s.Toincreasethedescentrate
pullharderontheBrisers.WhenyoureleasetheBrisersthecanopywillautomaticallystartyingagain,normally
withintwoseconds.SometimesthecanopywillturngentlywhenitexitsfromtheB-linestall.Itisnormallybetterto
releasetheBrisersfairlyquicklyratherthanslowly,toavoidthecanopyenteringdeepstall.Alwaysreleasetherisers
symmetrically.AnasymmetricreleasefromaB-linestallmayresultinthegliderenteringaspin.Thismanoeuvreis
usefulwhenyouneedtolosealotofheightquickly,perhapswhenescapingfromathunderstorm.Itshouldnotbe
performedwithlessthan100mofgroundclearance.(seealsoChapter5).

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enteranover-the-nosespiral.
BGDglidersaredesignedandtestedtorecoverfromnormalspiralswithadescentrateinferiorto16m/s,
automaticallywithoutpilotinput.Ifthepilotincreasesthedescentrateofthespiraltoover16m/sorinitiateswhatis
knownasanover-the-nosespiral,theglidermayrequirepilotinputtorecover.Inthiscaseallthepilotneedstodois
toapplysomeoutsidebrakeandsteertheglideroutoftheturn.
Theover-the-nosespiralisaspecialtypeofspiraldivewherethegliderpointsalmostdirectlyattheground.You
caninitiateitbymakingasuddenbrakeapplicationduringthespiralentry.Thegliderwillyawaroundandenterthe
manoeuvre,itsnosepointingattheground,afterthistheglider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practice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!

Thegliderwillcomeupmoreeasilytolaunchinthisconguration.Inordertoreducethebrakepressureinightthe
trimmerscanbesettotheslowestposition,buttrytoavoidusingtheslowesttrimmerpositionifyouareyingnear
thebottomoftheweightrange(below150kgall-upweight).Ifyouarenearthetopoftheweightrange(over200
kgall-upweight)itisbettertoalwaysywiththetrimmersappliedfully(slowsetting),exceptforattakeoff.Flying
withthetrimmersintheslowpositionhelpstoreducethebrakepressureandmakesyingwithheavierweightsmore
comfortable.
IMPORTANT:
• Practiseusingthetrimmersysteminnormalying.
• Becarefulyingfastin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.
• Rememberthatyour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.The
trimmerscanbeeasilyreplacedbythepilotiftheybecomeworn.EveryDUAL/DUALLITEisdeliveredwithaspare
set.
Landing
LandingtheDUAL/DUALLITEisverystraightforward.Flareinthenormalwayfromanaltitudeofaround2mwhen
landinginlightwinds.Itmaysometimeshelptotakewrapsonthebrakestomakethearemoreeffective.Inzero
windconditionsithelpstousethependulumeffectoftheglidertogiveaperfectstand-uplanding.Trimmersshould
bereleased25mm,asfortakeoff(onthewhitemark),fortheperfectlandingare.

Stallsaredangerousandshouldnotbepracticed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.Ifyoudorelease
thebrakesquicklyyoushouldbrakethecanopystronglyduringthesurgeforward,tostopthedive.Allpilotswhoy
theDUAL/DUALLITE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DUAL/DUALLITE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:
• Verylowairspeed
• Almost-verticaldescent(likearoundcanopy),typicallyaround5m/s.
• Theparagliderappearsquitewellinatedbutdoesnothavefullinternalpressure.Itlooksandfeelsabitlimp.

Version 1.2 July 2018
Recoveryfromdeepstallisquitesimple:
Thenormalmethodistoreleasethetrimmerstothefastposition.Normalightshouldberecoveredin2to4
seconds.
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surgeforward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practiced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DUAL/DUALLITE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DUAL/DUALLITE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DUAL/DUALLITE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DUAL/DUALLITEitshouldbevery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
willstill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DUAL/DUALLITE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.

Packing
TheDUAL/DUALLITEcanbepackedinatraditionalroll-upmethod,orconcertinafolded.Concertinafoldingwill
helpextendthelifeoftheglider.
1. Selectasuitableatareathatisoutofthewindifpossible.
2. Arrangethecanopywiththeundersidefacingupwardsandtheharnessatthetrailingedge.Layallthelines
onthecanopy.Atthisstageyoumaywishtoremoveyourharness.
Nowdifferenttechniquescanbeuseddependingonthekindofinnerbagyouuse:
Stuffsack
3. Rollupthecanopyinsectionsfromeachtipinwards.
4. Thenstartingfromtheharnessatthetrailingedge,rollupthecanopysqueezingoutalltheairatthesame
time.
Therolledcanopywillnowtneatlyintoitsbag.

4. Concertinatheleadingedgetogetherwithalltheplasticslyingsidebyside.Avoiddraggingtheleadingedge
overthegroundduringthisprocedure.
5. Laytheglideronitssideandputthestrapsaroundtheleadingedge.
6. Nowsqueezetherestoftheairoutofthecanopyandclosethezip.
7. Finallyfoldthebaginthreemakingsuretheleadingedgeremainsunfolded.
Storage & Care
Ifyouhavetopackawayyourcanopy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DUAL/DUALLITEismadefromhighqualitynylon,whichistreatedagainstweakeningfrom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layinginstrongsunshineunnecessarily.Ifyouareconcernedaboutanyaspectoftheintegrityofyourparaglider
pleasecontactyournearestBGDdealerortalktoBGDdirectly.
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.
