into normal flight, i.e get control of your direction and then pull down
the stabilo line (green line on the B riser) until the wing tip frees
itself. 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 it and can only be done with a large amount of alti-
tude. Remember if the rotation is accelerating and you are unable to
control it, you should use your reserve parachute whilst you still have
sufficient altitude.
IMPORTANT: A bad preparation on launch, aerobatic fly-
ing and flying a wing of too high a level or in conditions too
strong for your ability are the main causes of cravats.
Deep Stall / Parachutal stall
It is possible for gliders to enter a state of parachutal stall. This can
be caused by several situations including; a very slow release from
a B-line stall; flying the glider when wet; or after a front/symmetric
deflation. The glider often looks as though it has recovered properly
but carries on descending vertically without full forward motion. This
situation is called ‘deep stall’ or ‘parachutal stall’.
It is unlikely to happen on any Ozone glider, but should it happen, your
first reaction should be to fully raise both brakes, and return trim-
mers to the white line if set on slow. This normally allows the glider
to return to normal flight. If nothing happens after a few seconds,
reach up and push the A-risers forwards or apply the speed bar to
regain normal flight.
Ensure the glider has returned to normal flight (check your airspeed)
before you use the brakes again.
IMPORTANT: Only a few cms of input from your brakes can
maintain your wing in the stall. Always release your wraps
if you have taken them!
INCIDENTS
Deflations
Due to the flexible form of a paraglider, turbulence may cause a por-
tion of the wing suddenly to collapse. This can be anything from a
small 30% (asymmetric) collapse to a complete (symmetric) collapse.
If you have a collapse, the first thing to do is to control your direc-
tion. You should fly away from the ground or obstacles and other
pilots, or at least not to fly into them... 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 deflated 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 flying. If you
are unable to stop the glider turning without exceeding the stall point
then allow the glider to turn whilst you reinflate the collapse.
If you do have a deflation, which does not spontaneously reinflate,
make a long smooth progressive pump on the deflated side. This
pumping action should take about 2 seconds per pump. Pumping too
short and fast will not reinflate the wing and pumping too slow might
take the glider close to, or beyond, the stall point.
Symmetrical collapses reinflate without pilot input, however 15 to
20cm of brake applied symmetrically will speed the process.
If your Trickster collapses in accelerated flight, immediately release
the accelerator to slow down to trim speed and actively recover the
wing.
Cravats
If 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 difficult to control.
The first solution to get out of this situation is to stabilise the glider
