1 Introduction

Version 1.0 March 2017

TheBASELITEisanentry-levelparaglidersuitableforintermediatepilotsofferingahighlevelofpassivesafety

combinedwithspeedandgoodperformancewhichmakethisawingarealpleasuretoy.

Theuseofthisgliderislimitedtonon-aerobaticmanoeuvres.

Thisparaglidermustnot:

• Beownwithmorethanthemaximumcertiedtotalload

• Haveitstrimspeedadjustedbychangingthelengthofrisersorlines

• Beowninrainorsnow

• Betowedwithatowlinetensioninexcessof200kg.

Itisyourdealer´sresponsibilitytotestytheparagliderbeforeyoureceiveit.Thetestightrecordisonpage29

ofthismanual.Pleasebesurethatithasbeencompletedbyyourdealer,toprovethatthetestighthasbeendone.

Failuretotestyanewparaglidermayinvalidateanywarranty.

Anymodication,e.g.changeoflinelengthsorchangestothespeedsystem,causesalossofairworthinessand

certication.WerecommendthatyoucontactyourdealerorBGDdirectlybeforeperforminganykindofchange.

1 Introduction

Version 1.0 March 2017

2 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asthecentreofthearch.Theharnessshouldbedrawnawayfromthecanopyuntilthe

suspensionlinesarejusttight.

Version 1.0 March 2017

3 Pre-ight Inspection

TheBASE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.

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while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thepilotattacheshimselftotheharnessheshouldbewearingagoodcrashhelmet,andbootswhich

provideanklesupport.Putontheharnessensuringallthebucklesaresecureandproperlyadjustedforcomfort.

Yourparagliderisnowreadyforight.

4 Flight Characteristics

ThismanualisnotintendedasaninstructionbookonhowtoytheBASELITE.Youshouldbeaqualiedpilotor

undersuitablesupervision,butthefollowingcommentsdescribehowtogetthebestfromyourBASELITE.

Weight range

EachsizeoftheBASELITE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toytheBASELITEinthemiddleoftheweightrange.

IfyouytheBASELITE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BASELITEtowardsthelowerendoftheweight

range.

IfyouytheBASELITE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

EventhoughtheBASELITEisdesignedasaneasy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

Version 1.0 March 2017

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BASE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BASE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.

Approved harness dimensions

ThisgliderhasbeentestedwithaharnessthatcomplieswiththeENstandardharnessdimensions.

Thesearelaidoutinsection3.5.6andare:

Seatboard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BASE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.The‘big-ear’riserscouldbealsoheldforthebestination.

Forward launch

InationisbestdonebytakingtheA-risersoneineachhand.TheA-risersaremarkedwithredclothtomakethem

Version 1.0 March 2017

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BASE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BASELITE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BASELITEiesverywelllikethis,butcaremustbetakennottoover-applythebrakesasa

spincouldresult,althoughtheBASELITEhasaverylowspintendency.TheBASELITEwillturnfarmoreefciently

ifthepilotweight-shiftsintotheturn.Rememberthatviolentbrakeapplicationisdangerousandshouldalwaysbe

avoided.

Straight Flight

TheBASELITEwillysmoothlyinastraightlinewithoutanyinputfromthepilot.Withapilotweightof70kgonthe

mediumsizewithouttheacceleratortheyingspeedwillbeapproximately39km/h.

4FlightCharacteristics

Version 1.0 March 2017

Thermalling

ToattainthebestclimbratetheBASE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

(100m).

Wing Tip Area Reduction (Big Ears)

The‘babyA-riser’allowstheBASELITEtobe‘big-eared’simplyandeasily.Thebig-earfacilitydoesnotallowyouto

yinstrongerwinds,butiwhichallowsyou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.
