•Ensurebothmainbrakelinesareofequallength.

•Ifabrakehandlehasbeenremoved,checkthatitslineisroutedthroughthepulleywhenitisreplaced.

preventsthetrailingedgefrombeingdeformedwhenusingthespeedsystem.

Risers

TheUltralite4hasbeendesignedwith3risersperside.TheAriseriscoveredwithcolouredwebbing,to

allowforeasyidentication.

Therisersdonotfeaturetrimmers.

IMPORTANT

In the unlikely

event of a brake line

snapping in ight, or

a handle becoming

detached, the glider

can be own by

gently pulling the rear

risers (C-risers) for

directional control.

PREPARATION

IMPORTANT

Using the accelerator

decreases the angle

of attack and makes

the wing more prone

to collapse, therefore

using the accelerator

near the ground or in

turbulent conditions

should be avoided.

NOTE

It is recommended

to pilot the wing with

the rear risers during

accelerated ight.

Accelerator System

BASIC FLIGHT TECHNIQUES

IMPORTANT

Never take off with

a glider that is not

fully inated or if you

are not in control of

the pitch/roll of your

wing.

Launching

YourUltralite4willlaunchwitheithertheforwardorreversetechnique.Thewingshouldbelaidoutina

pronouncedarc,withthecentreofthewinghigherthanthetips.

Forward Launch - Nil to Light winds

Whenthewindisfavourable,whilstgentlyholdingtheArisersmoveforwardpositively,yourlinesshould

become tight within one or two steps and the Ultralite 4 will immediately start to inate. You should

maintainaconstantpressureontherisersuntilthewingisoverhead.Donotpulldownorpushtherisers

forwardexcessively,ortheleadingedgewilldeformandpossiblycollapsemakingtaking-offmoredifcult

andpotentiallydangerous.

Movesmoothlythroughouttheentirelaunch,thereisnoneedtorushorsnatchatit.Youshouldhave

plentyoftimetolookupandcheckyourcanopybeforecommittingyourself.Onceyouarehappythatthe

Ultralite4isinatedcorrectly,acceleratesmoothlyoffthelaunch.

Reverse Launch - Light to Strong Winds

Layoutyourwingasyouwouldfortheforwardlaunch.However,thistimeturntofaceit,passingone

entiresetofrisersoveryourheadasyouturn.Nowyoucaninatethegliderwithyourbodyweightand

theA-risers.Oncethewingisoverhead,releasetherisers,brakegentlyifnecessary,turnandlaunch.

Instrongerwinds,bepreparedtotakeafewstepstowardsthegliderasitinates.Thiswilltakesomeof

theenergyoutoftheglideranditwillbelesslikelytooveryyou.Thisreverse-launchtechniquecanbe

usedinsurprisinglylightwindstoo.

Practicegroundhandlingasmuchaspossible!Notonlyisitgreatfun,butitwillgiveyouamuchbetter

feelforyourwing’sightcharacteristics.Itwillalsoimproveyouroverallenjoymentofyingbygivingyou

thefeelingofcontrolandmakingyourlauncheseasierandlessstressful.

Speed to Fly

Flyingattrimspeed(hands-up),theUltralite4willachieveits‘bestglide’speedforstillair.Youshouldy

atthisspeedwhenglidingdownwindorwhentheairisnotexcessivelysinking.Forbetterpenetrationin

headwindsandimprovedglideperformanceinsinkingair,crosswindsorheadwinds,youshouldyfaster

thantrimspeedbyusingtheacceleratorsystem.Usinguptohalfbardoesnotdegradetheglideangleor

stabilitysignicantlyandwillimproveyouryingperformance.Youwillreachthenextthermalfasterand

higher.AtfullspeedtheUltralite4isstable;howeverwerecommendthatyoudonotyatfullspeedclose

tothegroundorinturbulentair.

Byapplyingthebrakesapproximately20cm,theUltralite4willachieveitsminimum-sinkrate;thisisthe

speedforbestclimbandisthespeedtouseforthermallingandridgesoaring.

Turning

Tofamiliarize yourselfwiththe Ultralite4your rstturnsshould begradualand progressive.Tomake

efcientandcoordinatedturnswiththeUltralite4rstlookinthedirectionyouwanttogo,thenleaninto

it.Yourrstinputfordirectionalchangeshouldbeweight-shift,followedbythesmoothapplicationofthe

brakeuntilthedesiredbankangleisachieved.Toregulatethespeedandradiusoftheturn,coordinate

yourweightshiftandusetheouterbrake.

Active Flying

Tominimizethelikelihoodofsufferingcollapsesinturbulentconditions,itisessentialtouseactiveying.

Theseareskillsthatarebestlearntbyplayingwiththegliderontheground.Flyingwithasmallamountof

brakeapplied(approx.20cm)willallowyoutofeelthefeedbackfromthewing.Inturbulentconditionsthe

internalpressureofthewingisconstantlychangingandonlybyusingasmallamountofbrakewillyoufeel

thesechanges.Theaimofactiveyingistomaintainaconstantpressurethroughthebrakes,Ifyoufeela

reductionorlossofpressureapplythebrakesuntilyoufeelnormalpressureagain.Onceyouhavenormal

pressure,raisethehandsquicklybacktotheoriginalposition.Avoidyingwithcontinuousamountsof

deepbrakeinroughairasyoucouldinadvertentlystallthewing.Alwaysconsideryourairspeed.

Thesemovementscanbesymmetricorasymmetric;youmayhavetoapplybothbrakesorjustone.These

subtleadjustmentswillkeeptheglideryingsmoothlyanddirectlyaboveyouanddramaticallyreducethe

chancesofacollapse.Ifthegliderpitchesinfrontofyou,usethebrakestoslowitdown.Equally,ifthe

gliderdropsbehindyou,releasethebrakestoallowittospeedup.Thegoalistoalwayskeepthewing

directlyoverhead.

Nopilotandnogliderareimmunetocollapseshoweveractiveyingwillvirtuallyeliminateanytendencyto

collapse.Whentheconditionsareturbulent,bemoreactiveandanticipatethemovementsofyourwing.

IMPORTANT

Always keep hold of

your brakes. Do not y

in turbulent conditions

IMPORTANT

Never initiate a turn at

minimum speed (i.e.

with full brakes on) as

you could risk entering

a spin.

Landing

TheUltralite4showsnounusuallandingcharacteristicsbutasareminder,herearesometips:

•Alwayssetupforyourlandingearly,giveyourselfplentyofoptionsandasafemarginforerror.

•Oncebelow30metresavoidturningtightlyasthegliderwillhavetodivetoacceleratebacktonormal

ight. If you are at low altitude, or if you hit sink, this could mean you hit the ground harder than

necessary.

•Leanforwardoutofyourharnessbeforetheactuallanding(especiallyifit’sturbulent),withyourweight

leaningforwardagainstthecheststrap,andmakesureyourlegsarereadyforthelandingandapossible

PLF(parachutelandingfall).

•Allowtheglidertoyathandsup(trim)speedforyournaldescentuntilyouarearound1metreabove

theground(inwindyorturbulentconditionsyoumustytheglideractivelyalltheway).Applythebrakes

Ozone strongly recommend to NOT perform Spiral Dives with Big Ears engaged.

IMPORTANT

Induce Big ears one

side at a time

NEVER induce Big

Ears in accelerated

ight, this can lead

to a major deation.

Always pull the Big

Ears rst and then

apply the speed bar.

DO NOT perform spiral

dives with Big Ears

engaged.

MPORTANT

The pitching movement

on exiting the B stall is

small but necessary.

We recommend you do

not brake the glider

until you are sure that

the glider is ying

properly

again.

IMPORTANT

Always be prepared

to pilot the wing out

of a spiral dive. Use

opposite weight shift

and apply enough

outside brake to

stop the wing from

spiralling.

IMPORTANT

Never apply the brakes

whilst using the speed

system - it makes the

wing more prone to

collapse.

INCIDENTS IN FLIGHT

WARNING

Uncoordinated

wingovers can lead

to large asymmetric

collapses and cravats,

therefore they should

never be executed

near the ground.

Deﬂations

Duetotheexibleformofaparaglider,turbulencemaycauseaportionofthewingsuddenlytocollapse.

Deep Stall / Parachutal Stall

It is possible for gliders to enter a state of parachutal stall. This can be caused by several situations

including;averyslowreleasefroma B-line stall; ying the gliderwhenwet;orafterafront/symmetric

deation.Theglideroftenlooksasthoughithasrecoveredproperlybutcarriesondescendingvertically

IMPORTANT

Only a few cms of

input from your

brakes can maintain

your wing in the stall.

Always release your

wraps if you have

taken them!

IMPORTANT

A bad preparation

on launch, aerobatic

ying, ying a wing of

too high a level or in

conditions too strong

for your ability, are

the main causes of

cravats.

IMPORTANT

Never y in the rain or

with a wet glider
