Rapid Descent Techniques - Ozone ultralite Betriebshandbuch

• Always land heading into wind!
• In light winds you need a strong, long and progressive flare to bleed off all your
excess ground speed. In strong winds your forward speed is already low so you are
flaring to soften the impact as you touch down.
• If the wind is very strong, and you feel you might be dragged, stall the glider with the
C risers. This stalls the Ultralite in a very quick and controllable way and will drag you
less then if you use the brakes.
Packing
• Spread the glider flat on its top surface, then lay the lines on top. The risers should
be laid on the ground, at the centre of glider, near the trailing edge.
• Take a wing tip and fold it in to the centre of the wing. Repeat this until the glider is
folded up and approx. 60 cm's wide.
• Push out any remaining air by flattening the folded wing from the trailing edge to the
leading edge.
• Fold the glider so that the bundle is approximately the size and shape of the OZONE
rucksack. Never roll the wing up as this introduces unnecessary stresses into the
fabric.
• Always pack your Ultralite as loosely as you can, as every fold weakens the cloth on
any paraglider.
• Finally, wrap the glider tie around the bundle and put it in the stuff sack.
• Packing your glider using the concertina method, keeping the mylar stiffners flat may
prolong the life your glider.

RAPID DESCENT TECHNIQUES

Ozone would like to remind you that these manoeuvres should be learnt under the
supervision of a qualified instructor and always used with caution. Never forget that
properly analysing the conditions before launch will help avoid the need to use these
techniques.
Big Ears
Folding in the wingtips of the ULTRALITE increases its sink rate. To pull big ears on the
ULTRALITE, keep holding your brake handles and take the outermost A-line on each
side, then pull it down until the tips of the wing fold under.
Do not use the brakes other than for re-inflation. For directional control while using the
Big Ears, you should use weight shift steering.
To reopen your ears, release the outside A line: the glider should reopen automatically.
You can still help the reinflation by braking gently, one side at a time to minimise the
chance of inducing a stall.
IMPORTANT:
You can land with the ears (you should release the ears before
final flare). But Ozone don't advise you to do this when it's turbulent or windy
due to the risk of a possible stall and lack of precision in steering.
Big ears and accelerator
Once the big ears are in you can further increase the sink rate by pushing on the
accelerator bar.
NEVER try to pull the Big Ears in with the speed bar on. This can lead to a major
asymmetric deflation.
Big ears and spiral dive
Whilst it is possible to enter a spiral dive whilst holding in Big Ears, the high forces
applied to the lower lines could exceed the breaking strain of the lines leading to
equipment failure!
Ozone do not recommend the use of this manoeuvre!
B-Line Stall
B-stall is for fast descents in emergency situations only. B-stall is performed by
symmetrically pulling down on the B-risers.
To initiate the B-stall place your fingers between the lines on the B risers. Do not
release the brake handles. As you pull the B-lines down the airflow over the wing is
broken and the glider loses its forward speed but remains open and you will descend
at around 6 m/s.
To exit the B-stall the B-risers should be released symmetrically and in one smooth,
progressive motion. The glider will resume normal forward flight without further input.
Check you have forward flight again before using the brakes.
IMPORTANT:
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 flying again.
The load applied on the B lines during this manoeuvre is not very good for your
glider, only use it in emergency situations.
Spiral Dives
If you turn your Ultralite in a series of tightening 360's it will enter a spiral dive. This will
result in rapid height loss. To initiate a spiral, look and lean in to the direction you want
to go, then smoothly pull down on the inside brake. The Ultralite will first turn almost
360 degrees before it drops in to the spiral. Once in the spiral you must apply a little
outside brake to keep the outer wing tip pressured and inflated.
Safe descent rates of 8 metres per second (500 ft/min approx.) are possible in a spiral
dive, but at these rates the associated high speeds and G-forces can be disorientating,
so pay particular attention to your altitude.
To exit the spiral dive, return your weight shift to a central position and then slowly
release the inside brake. The Ultralite shows no indication of remaining neutral in the
spiral dive, however if it does so,you should always be prepared to pilot the wing out.
