In the unlikely
event of a brake line
snapping in ight, or
a handle becoming
detached, the glider
can be controlled by
gently pulling the rear
risers (C-risers).

PREPARATION
07
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.
Accelerator System
Tosetuptheacceleratorsystem,rstroutethelinessuppliedwiththespeedsystemthroughtheharness.
Makesurethisisdonecorrectlyandthatthelinespass throughallofthepulleys(checkyourharness
manualforinstructions).Attachthespeedsystemlinestotheacceleratorsystemontheriserswiththe
Brummelhooks.
Abasic set-up can be performed on the ground: ask a friend to pull the risers tight into their in-ight
positionwhilstyousitintheharnessontheground.Nowadjustthelengthsofthelinessothatthemain
barsitsjustbeneathyourseat.Youshouldbeabletohookyourheelintothelowerloopoftheaccelerator.
TheremustbeenoughslackinthespeedsystemtoensuretheArisersarenotinadvertentlypulledduring
normaltrimspeedight,butnotsolongthatitisimpossibletousethefullspeedrangeoftheglider.Fully
extendingthelowerloopofthespeedbarwillacceleratethewingtoapproximatelyhalfitsaccelerated
speedrange.Forfullspeed,hookyourheelsontotheupperbarandsmoothlyextendyourlegs,maximum
speed is when the pulleyson the risers overlap. Onceset up, test the full range of the accelerator in
calmyingconditionsandensurethatbothrisersarepulledevenlyduringoperation.Fine-tuningcanbe
completedwhenyouarebackontheground.
Harness
Itisimportanttosetupyourharnesscorrectlybeforeyingthewing.Makesuretospendtimeadjusting
your harness’s different settings until you are completely comfortable. We recommend a chest strap
settingbetween44cmand48cm(measuredbetweenthecentreofthehangpoints).

haveaninuenceonthebehaviourofthewing.Podharnessesincreasetheriskoftwistsoccurringduring

BASIC FLIGHT TECHNIQUES
09
IMPORTANT
Never take o with
a glider that is not
fully inated or if you
are not in control of
the pitch/roll of your
wing.
Launching
TheJomo2canbelaunched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wingwillimmediatelystarttoinate.Youshouldmaintain
aconstantpressurethroughtheharnessandontherisersuntilthewingisoverhead.Donotpulldown
orpushtherisersforwardexcessively,thiswillcausetheleadingedgetodeformandpossiblycollapse,
makingthetake-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
wing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.
Speed to Fly
Flyingattrimspeed(hands-up),theJomo2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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Jomo2isstable,howeverwerecommendthatyoudonotyatfullspeedclose
tothegroundorinturbulentair.

Byapplyingapproximately20cmofbrakestheJomo2willachieveitsminimum-sinkrate;thisisthespeed
touseforthermallingandridgesoaringinliftingair.
Turning
TofamiliarizeyourselfwiththeJomo2yourrstturnsshouldbegradualandprogressive.Tomakeefcient
andcoordinatedturns,rstchecktheairspaceisclearandthenleantowardsthedirectionyouwishto
turn.Therstinputfordirectionalchangeshouldbeweight-shift,followedbya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withtheinnerand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

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.

NEVER induce Big

I
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.

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

IMPORTANT
Only a few cms of
input from your brakes
can maintain the wing
in a parachutal stall.
Always release your
wraps if you have
taken them!
IMPORTANT
A bad preparation
on launch, poorly
executed aerobatics
and ying in
conditions too strong
for your ability are
the main causes of
cravats.
