Ozone Roadster - Cravats

Asymmetric collapses can be controlled by weight shifting away from the collapse and
applying a small amount of brake to control your direction. This act will most of the
time be enough for a full recovery of the wing
.
Once a glider is deated it is effectively a smaller wing, so the wing loading and stall
speed are higher. This means the glider will spin or stall with less brake input than
normal. In your efforts to stop the glider turning towards the collapsed side of the wing
you must be very careful not to stall the side of the wing that is still ying. If you are
unable to stop the glider turning without exceeding the stall point then allow the glider
to turn whilst you reinate the collapse.
If you do have a deation, which does not spontaneously reinate, make a long
smooth progressive pump on the deated side. This pumping action should take
about 2 seconds per pump. Pumping too short and fast will not reinate the wing and
pumping too slow might take the glider close to, or beyond, the stall point.
Symmetrical collapses reinate without pilot input, however 15 to 20cm of brake
applied symmetrically will speed the process. If you simulate a symmetrical collapse
during an SIV course it is important to use both the A and Baby A risers and to pull
evenly to induce a symmetrical collapse. Use of just A risers or uneven pulling may
lead to the glider collapsing only in the centre section with the tips ying forward to
meet in the middle, leading to an increased risk of a cravat occurring.
If your Roadster collapses in accelerated ight, immediately release the accelerator to
slow down to trim speed and after a 90 deg turn the canopy will reinate and return to
normal ight.
Cravats
When the tip of your wing gets stuck in the lines, this is called a 'cravat'. This can
make your glider go into a spiral, which is difcult to control. The rst solution to get
out of this situation is to stabilize the glider into normal ight by maintaining control of
your direction and then pull down the stabilo line (red line on the B-riser) until you feel
tension to help release the tip. You must be careful with any brake inputs or you may
stall the opposite wing.
If this does not work, a full stall (symmetrical or asymmetrical) is the only other option.
This should not be done unless you have been taught how to do so and it can only be
done with a safe amount of altitude. Remember if the rotation is accelerating and you
are unable to control it, you should use your reserve parachute whilst you still have
enough time and altitude.
IMPORTANT: A bad preparation on launch, aerobatic ying, ying a wing of too
high a level or in conditions too strong for your ability, are the main causes of
cravats.
ACROBATIC FLYING
The Roadster has been designed as paramotoring wing and is not suitable for
acrobatic manoeuvres.
A specic standard of certication for acrobatic ying has not been set up yet. Ozone
wings although designed to the highest specications are, therefore, not certied for
this type of ying. As acrobatic manoeuvres are very difcult and incorrectly performed
manoeuvres can put abnormal stresses on the glider and lead to loss of pilot control,
Ozone strongly recommend you do not undertake this style of ying.
MATERIALS
All OZONE gliders are made from the highest quality materials available. Porcher cloth
has been used for all components of the glider due to its lighter weight and stretch
resistance, which are two important factors in a high performance wing.
Upper-surface
Porcher Skytex 45 evolution.
Lower-surface
Porcher Skytex 40 classic
Internal Ribs
Mix of Porcher Skytex 45 and 40 Classic and hard coatings.
Leading- edge reinforcement
Double Laminated Mylar.
Line Set
Lower cascades - Edelrid 6843, 200kg
