The tearing resistance of the cloth - A non-destructive test following the TS-108 standard which specifies
minimum tear strength for sky diving canopies should be made using a Bettsometer. (B.M.A.A. Approved
Patent No. GB 2270768 Clive Betts Sails)
Strength of the lines - An upper, middle and lower A line, along with a lower B and a lower C (and lower D if
applicable) line should be tested for strength. Each line is tested to breaking point and the value 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 the middle lines and for the
top lines should be the same. If the breaking strength is too close to the minimum value calculated, the
professional should give a period after which you will 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
5Kgs 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 or Ds and/or a slight stretch on the
A, B. The consequences of these changes can include a slower trim speed, difficult inflation etc.
Risers - Visual inspection for signs of wear or abrasion. Differences to manual lengths should not exceed
+/-5mm.
Canopy check - A full visual check should be carried out: All the components of the wing (stitching, ribs,
diagonals, lines, tabs, ...) should be checked for signs of deterioration.
Finally, a flight test to confirm that the wing behaves normally should be carried out by a professional.
IMPORTANT
Take care of your
glider and make sure
you have it checked
and serviced according
to the schedule.
Total Weight in flight
Each Ultralite 4 has been certified with a wide weight range with plenty of overlap between sizes,
we strongly recommend that you respect the limits. If you are an experienced pilot who requires the
most compact and lightest wing for serious hike and fly then you should chose from the smaller sizes
depending on your needs. If you are less experienced or want a wing more optimised for thermalling and
XC then the larger sizes are more suitable. For better speed, precise handling or if you generally fly in
mountains and/or in strong conditions, you should chose to fly in the top part of the weight range. If you
want a better sink rate for thermalling and XC you may choose to fly lower in the weight range.
Towing
The Ultralite 4 may be tow-launched. It is the pilot’s responsibility to use suitable harness attachments
and release mechanisms and to ensure that they are correctly trained on the equipment and system
employed. All tow pilots should be qualified to tow, use a qualified tow operator with proper, certified
equipment, and make sure all towing regulations are observed.
Flying in the Rain
Modern wings are susceptible to rain and moisture, flying with a wet wing can result in the loss of normal
flight. Due to the efficient, wrinkle-free design of the sail, water tends to bead on the leading edge causing
flow separation. Flow separation will make the wing more prone to entering inadvertent parachutal stalls,
so flying in the rain, or with a wet wing (e.g early morning dew) should be avoided at all costs.
If you are accidently caught-out in a rain shower, it is best to land immediately. If your wing becomes wet
in the air it is advised to maintain accelerated flight using the speed bar, even during the final approach.
DO NOT use big ears as a descent technique, the increased drag will increase the chance of a parachutal
stall occurring. Instead, lose height with gentle 360’s and maintain your air speed at all times. If your wing
enters parachutal stall when wet, immediately accelerate the wing to regain airspeed.
Modifications
Your Ozone Ultralite 4 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 glider in any way.
