Deflations
Duetotheexibleformofaparaglider,turbulencemaycauseaportionofthewingsuddenlytocollapse.
Thiscanbeanythingfromasmall30%(asymmetric)collapsetoacomplete(symmetric)collapse.
Ifyouhaveacollapse,therstthingtodoistocontrolyourdirection.Youshouldyawayfromtheground
orobstaclesandotherpilots.Asymmetriccollapsesshouldbecontrolledbyweightshiftingawayfromthe
collapseandapplyingenoughbraketocontrolyourdirection.Thisactionalonewillbeenoughforafull
recoveryofthewingmostofthetime.
Onceagliderisdeateditiseffectivelyasmallerwing,sothewingloadingandstallspeedarehigher.This
meansthegliderwillspinorstallwithlessbrakeinputthannormal.Inyoureffortstostopthegliderturning
towardsthecollapsedsideofthewingyoumustbeverycarefulnottostallthesideofthewingthatisstill
ying.Ifyouareunabletostopthegliderturningwithoutexceedingthestallpointthenallowthegliderto
turnwhilstyoureinatethecollapse.
Ifyouhaveadeationwhich does notspontaneously reinate,makealongsmoothprogressivepump
onthedeatedside.Thispumpingactionshouldtakeabout1-2secondsperpump.Pumpingtooshort
andfastwill not reinate thewingandpumpingtooslowmighttaketheglidercloseto,orbeyond,the
stallpoint.
Symmetricalcollapsesreinatewithoutpilotinput,however15to20cmofbrakeappliedsymmetricallywill
speedtheprocess.Afterasymmetriccollapsealwaysconsideryourairspeed.Makesurethegliderisnot
inparachutalstallbeforemakinganyfurtherinputs.
IfyourRush5collapsesinacceleratedight,immediatelyreleasetheacceleratorandmanagethecollapse
usingthemethodsdescribedabove.
Cravats
Ifthetipofyourwinggetsstuckinthelines,thisiscalleda‘cravat’.Thiscanmakeyourglidergointoa
spiral,whichisdifculttocontrol.Therstsolutiontogetoutofthissituationistostabilisethegliderinto
normalight,i.egetcontrolofyourdirectionandthenusestrongdeeppumpsofthebrakeonthecravated
side.Whendoingsoitisimportanttoleanawayfromthecravatotherwiseyouriskspinningordeepening
thespiral.Theaimistoemptytheairoutofthewingtip,butwithoutspinning.Correctlydone,thisaction
willclearthecravatquicklyandisthemostefcientandeffectivemethod.Youcanalsotrypullingonthe
stabiloline(CRL4-outsidelineontheCriser)tofreesmallstubbornwingtipcravats.Whichevermethod
youuse,becarefulwithanybrakeinputsasyoumaystalltheoppositewing.
Ifitisaverylargecravatandtheaboveoptionshavenotworkedthenafullstallisthenextoption.Only
attemptthisifyouhaveenoughaltitudeandyouknowwhatyouaredoing.Rememberiftherotationis
acceleratingandyouare unable tocontrolit,throwyour reserve parachuteimmediatelywhilstyoustill
haveenoughaltitude.
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
withoutfullforwardmotion.Thissituationiscalled‘deepstall’or‘parachutalstall’.
ItisunlikelytohappenonanyOzoneglider,butshoulditdosoyourrstreactionshouldbetofullyraise
bothhands.ThisnormallyallowstheglidertoreturntonormalightbutIfnothinghappensafterafew
seconds,reachupandpushtheA-risersforwardsorapplythespeedbartoencouragethewingtoregain
normalight. Ensurethe gliderhas returnedto normalight (checkyour airspeed)before you use the
brakesagain.
Donotyinrain,doingsosignicantlyincreasesthelikelihoodofparachutalstallsoccurring.Toreduce
thechanceofstallinginrainavoidusingdeepbrakemovementsorBigEars.Findasafeareatolandand
usingthespeedbar,maintainagoodairspeedatalltimes.
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.
WARNING
Uncoordinated
wingovers can lead
to large asymmetric
collapses and cravats,
therefore they should
never be executed
near the ground.
