I TRODUCTIO
Congratulations on your purchase of an Avian Java. The Java is the "state of the art"
high performance king post hang glider. We hope that you will experience many
hours of safe and enjoyable flying on your Java.
This manual is designed to help you get the most out of your Java:
Please read this manual completely before flying, check all your battens against the
batten profile (adjusting them if necessary) and do a thorough pre-flight check.
In your pre-flight include checking the operation of the VB. This is especially
important if instruments are attached to the right hand (VB.) upright.
If you are uncertain, or have any problems with your glider, DO OT FLY. We
have a section on trouble shooting in this manual that features some of the more
common problems that pilots have encountered, and our recommended solutions. If
you are still not sure contact your local dealer or the Avian factory. Both will be
pleased to help you. Make sure your first flight on your new glider is in perfect
conditions from a site that you are familiar with.
PLEASE OTE
Avian Ltd. do not have commercial product liability insurance.
Avian hang gliders are built using materials and fittings to the industry standard or
better. Avian hang gliders are subject to Avian quality control and testing prior to
delivery to the customer.
Once possession of the glider passes to the customer, its maintenance and condition
becomes the responsibility of the owner or pilot. Any concerns or queries about the
glider's subsequent air worthiness MUST be referred back to the local dealer or the
Avian factory.
Hang gliders like most aircraft must be:
·stored correctly,
·treated with respect,
·checked before take off and after heavy landings,
·regularly maintained and
·flown in suitable conditions within their flight envelopes .
Failure to do any of these courts disaster. Look after your aircraft!!

RIGGI G THE JAVA
The glider can either be rigged flat on the ground, or with the glider supported on its
control frame. The latter should only be attempted in very light wind conditions but is
useful in confined spaces or where the terrain is likely to cause soiling or damage to
the sail.
Rigging the Java flat
1. Lay the glider on the ground with the nose pointing into wind. Unzip the bag and
roll the glider so it is the right way up. Take the bag off. (If you tread on the inside
of the bag any dirt that you get on it will be transferred to the glider when you put the
bag on later.)
2. Take the glider ties off and take the battens out from alongside the kingpost. Raise
the aerofoil kingpost checking that the sail is not caught by the base of the kingpost.
Hook in the top rigging making sure that the anti-luff lines are not tangled.
3. Making sure that you do not lift the tip high above the ground (to ensure that you
do not bend the nose plates), swing one wing out about a quarter of its maximum
travel. Swing the other wing half of its maximum travel. Continue until both wings
are about three quarters of their maximum travel. Lift the wing preferably by the
wing tip but if you must use the sail hold it by the batten pocket ends on the trailing
edge. If there is any resistance check to see what is causing it and free the problem
before continuing. Do not attempt to force the wings apart.
4. Put the bottom bar on and insert the two stainless pins from the back of the base
bar and fit the safety rings. PUT THE RI GS I IMMEDIATELY. DO OT
LEAVE IT U TIL LATER. Thread the VB. cord through the eye of the quick ring
and through the cleat on the base bar. Tie a knot in the end of the cord.
5. Lay the battens on the ground and pair them up, red with green, and check that
corresponding batten pairs have the same profile. This is a good habit to get into as it
will reduce the chances of taking off on a glider with a turn caused by asymmetric
shaped battens. (Periodically the battens should be checked against the batten
profile.)
6. Put the curved battens in their pockets working from the tip towards the centre
chord. Keep the trailing edge low and slowly ease the battens into their respective
pockets. This makes the job easier and the batten pockets last longer.
. The glider can now be tensioned. Remove the split ring from the special bolt
located through the rear of the keel tube. Using the attached elastic cord, pull the
cross tube restraint webbing back. (Check that the side wires are not caught around a
batten end or the ferrules caught in the under-surface of the sail.) Locate the stainless
tang over the stub of the bolt and replace the split ring. DO THIS OPERATIO
IMMEDIATELY. DO OT LEAVE IT U TIL LATER. (If the tension feels too
tight stop and see what is causing the problem. DO OT JUST FORCE IT.

Java 140 Owner`s Manual
Consult the trouble shooting area of this manual for possible causes.)
8. Push the battens home the last little bit. (With a new sail the battens may not go
fully home unless pushed.) The batten elastics should be put on double on each
batten.
9. Locate the washout rod. This can only be done with a tensioned glider. Put your
arm in the end of the sail, rotate the washout rod out until it is perpendicular to the
leading edge and locate the end of the rod on its stub. Lift the back of the sail and
you should hear the washout rod clunk into place. Now the batten nearest the wing
tip can be inserted. It locates on a plastic cleat on the leading edge. (These battens,
sometimes called compression struts, are profiled on the Java. Like all the other top
surface battens the curve should be up. The top surface of the wing should be convex
OT concave.)
10. The under surface battens should also be inserted when the glider is tensioned.
They should be pushed home so that only the rope projects from the batten pocket.
Put the most outboard U/S batten in first. The under surface battens can be pushed
home with another under surface batten.
11. Put in the nose batten. This is easier with the VB. on full. Some people prefer to
put the nose batten in before the wings are moved out at all or to leave the nose batten
in the glider when packed. (If you do this don't forget to check its profile when you
check the profile of the other battens. It will go flat.)
12. Make sure that the wires are not twisted, then stand the glider on its control
frame and attach the swan catch, pip pin and safety washer.
13. Make sure that the nose catch is correctly attached and then put the nose cone on.
14. The glider is now fully rigged. You should now make sure that you do a
thorough pre-flight check before you fly.
We suggest that if there is significant wind that the glider is left flat on the ground,
nose into wind and securely weighted or tied down at the nose until you are ready to
fly.
In light winds the Java maybe left standing on its 'A' frame tail into wind. In this
position it is obviously prone to being ground looped by gusts of wind, thermals or, in
hotter countries, dust devils. We strongly recommend that you keep a close eye on it.
Rigging the Java standing on its A-frame
This is useful in confined spaces or where the terrain is likely to cause soiling or
damage to the sail. It is essentially very similar to rigging the glider flat:
1. Lay the glider on the ground. If there is any wind the nose should be pointing

cross or down wind. Unzip the bag and take enough ties off to assemble the A frame.
Assemble the A frame. Put the bottom bar on and insert the two stainless pins from
the back of the base bar and fit the safety rings. PUT THE RI GS I
IMMEDIATELY. DO OT LEAVE IT U TIL LATER. Thread the VB. cord
through the eye of the quick ring and through the cleat on the base bar. Tie a knot in
the end of the cord.
2. Stand the glider on its A-frame and then take the bag and remaining ties off, and
remove the battens from alongside the kingpost.
3. Walk the wings out to about three quarters of their full extension. As before the
wings should ideally be walked out together. If you are rigging by yourself move one
wing a bit and then move the other. NB: Whilst spreading the wings, particularly
when the glider is standing on its A frame, it is essential that the leading edges and
keel are kept in the same plane. (This is to avoid distortion to the nose plates or any
other components.)
4. Take care to place the tips on a piece of ground that is not likely to cause them
damage. Leave the tip socks on as this will protect them. The glider should now be
standing on its A frame, wing tips and keel.
5. Raise the aerofoil kingpost checking that the sail is not caught by the base of the
kingpost. Hook the top rigging in making sure that the anti-luff lines are not tangled.
Now making, sure that the wires are not kinked, attach the swan catch, pip pin and
safety washer. (You should always hook in the top rear rigging before attaching the
swan nose catch.)
6. Lay the battens on the ground and pair them up, red with green, and check that
corresponding batten pairs have the same profile. This is a good habit to get into as it
will reduce the chances of taking off on a glider with a turn caused by asymmetric
shaped battens. (Periodically the battens should be checked against the batten profile)
. Put the curved battens in their pockets working from the centre chord towards the
tip. Keep the trailing edge low and slowly ease the battens into their respective
pockets. Do not put in the last three or four battens each side.
8. The glider can now be tensioned. Remove the split ring from the special bolt
located through the rear of the keel tube. Using the attached elastic cord, pull back the
cross tube restraint webbing, locate the stainless tang over the stub of the bolt and
replace the split ring. DO THIS OPERATIO IMMEDIATELY. DO OT
LEAVE IT U TIL LATER.
This operation is much easier if you get a friend to lift a wing while tensioning. DO
OT JUST FORCE IT. (If the tension feels too tight stop and see what is causing
the problem. Consult the trouble shooting section of this manual for possible causes.)
9. Take off the tip socks and put in the battens near the tip except for the last one.
Push all the battens fully home. (With a new sail the battens may not go fully home
unless pushed.) The batten elastics should be put on double on each batten.

10. Locate the washout rod. This can only be done with a tensioned glider. Put your
arm in the end of the sail, rotate the washout rod out until it is perpendicular to the
leading edge and locate the end of the rod on its stub. Lift the back of the sail and
you should hear the washout rod clunk into place. Now the batten nearest the wing
tip can be inserted. It locates on a plastic cleat on the leading edge. (These battens,
sometimes called compression struts, are profiled on the Java. Like all the other top
surface battens the curve should be up. The top surface of the wing should be convex
OT concave.)
11. The under surface battens are more easily inserted once the glider has been
tensioned. They should be pushed home so that only the rope projects from the
batten pocket. Put the most outboard U/S batten in first. The under surface battens
can be pushed home with another under surface batten.
12. Put the nose batten in and locate it on its seat just in front of the nose plate. This
operation is easier if the VB. is pulled on first. When the batten is in release the VB.
(Some pilots only remove the nose batten occasionally to check its profile.)
13. Double check that the nose catch is correctly attached and put the nose cone on.
14. The glider is now fully rigged and you should now make sure that you do a
thorough pre-flight check before you fly.
As the glider is standing on its A frame it is prone to being ground looped by gusts of
wind, thermals or, in hotter countries, dust devils. It is safest with its tail into wind
but we strongly recommend that you keep a close eye on it.
