Caring Tips
• Your Ozone wing has an opening closed using velcro on the trailing edge of the tip
called the 'butt hole'. This has been designed to easily empty all the things which have
been accumulating in your wing (sand, leaves, rocks, mobile phones etc).
• If you fly with a wrap, you should regularly undo the twisting that appears on the
main brake lines. By twisting the line become shorter and you can end up with a
constant tension on the trailing edge (which can lead to problem on launch, stalling,
glider not flying symmetrically, ...)
• Change your main brake lines if they are damaged.
MAINTENANCE CHECKS
Your wing, like a car, should be technically checked to ensure proper airworthiness.
If you ever sell your Geo 2, you should give to the buyer the actual revision certificat.
Your wing should be checked by a qualified professional for the first time after 24
months, and thereafter every 12 months. However, if you are a frequent flyer (more
than 80 hrs per year), then we recommend, that you get your glider checked after
every flying season.
The checker should inform you about the condition of your glider and if some parts will
need to be checked or changed before the next normal service check period.
The sail and the lines don't age in the same way : it is possible that you'll have to
change part or all of the lines during your wings life. This is why it is also important to
do a regularly check up to know the condition of all the components of your glider.
We recommend that the check up is carried out by a qualified professional.
You are responsible for your flying kit and your safety depends on it. Take care of your
equipment and have it regularly inspected. Changes in a wings flying behaviour, are
also indicators of the gliders aging, if you notice any changes you should have the
wing checked before flying again.
These are the basic elements of the check up (full details and permissable figures can
be found on our website):
Porosity is measured with a porosity meter, the time taken by a certain volume of
air to go through a certain surface of the cloth. The time in seconds is the result. A
measurement is done in a several places on the top surface along the span of the
glider behind the leading edge.
The tearing resistance of the cloth - A non-destructive test following the TS-108
standard which specifies minimum tear strength for sky diving canopies is executed.
Strength of the line - The centre lines are tested: The uppers, the middles, the lowers
on the A, B, Cs are all measured. The reason for this is because these are the lines
which bear most of the loads.
Each line is tested on a testing table where they are pulled until they break. The
breaking value is recorded. The minimum value is 8 G for all lower A+B lines and 6 G
for all lower remaining lines, calculated from the maximum certified flying weight of the
glider. The added minimum strength for middle lines and top lines is the same.
If the breaking strength is too close to the minimum value calculated, the professional
will give a period after which you'll have to test the strength of the lines again.
Lengths of the lines - The overall length (riser lines + mid lines + upper lines) has to be
checked under 5DaN of tension.
The difference between the measured length and the original length should not exceed
+/- 10mm.
The changes that could appear are a slight shrink on the C and a slight stretch on the
A, B. The consequences of these changes can include a slower trim speed, difficult
inflation etc.
Full check - A full visual check should be carried out: All the components of the wing
(stitching, ribs, diagonals, lines, tabs, ...) should be checked.
Finally, if in doubt, a flight test that confirms that the wing behaves normally can be
done by the professional..
IMPORTANT : Take care of your glider and make sure you have it checked
according to the above schedule: This will ensure you hours of safe flying.
MODIFICATIONS
Your Ozone Geo 2 was designed and trimmed to give the optimum balance of
performance, handling and safety. Any modification means the glider loses its
certification and will also probably be more difficult to fly. For these reasons, we
strongly recommend that you do not modify your Geo 2 in any way.
