INCIDENTS
Deflations
Due to the flexible form of a paraglider, turbulence may cause a
portion of the wing suddenly to collapse. This can be anything from
a small 30% (asymmetric) collapse to a complete (symmetric) col-
lapse.
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 apply-
ing 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 pump-
ing too slow might take the glider close to, or beyond, the stall
point. If your Speedster collapses in accelerated flight, immediately
release the accelerator to slow down to trim speed and after a 90
deg turn the canopy will reinflate and return to normal flight.
Symmetrical collapses reinflate without pilot input, however 15 to
20cm of brake applied symmetrically will speed the process.
IMPORTANT: Due to the nature of the tab positioning, induced col-
lapses do not simulate real life collapses. Ozone strongly recom-
mends to NOT perform SIV manoeuvres such as simulated asym-
metric/symmetric deflations with this wing. To do so properly,
and to be in line with certification requires the addition of collapse
lines to the leading edge which have to be mounted accurately.
for it to return to level flight without an excessive climb and surge.
Always be prepared to pilot the wing out of a spiral dive. In case of
neutrality/instability use opposite weight shift and smoothly apply
enough outside brake to provoke the glider to exit the spiral.
IMPORTANT: The Speedster is a small and dynamic wing,
the entrance of the Spiral dives is very quick and the sink
rate high. Spiral dives are dangerous and put unnecessary
strain on the glider, they cause disorientation and need time
and height to recover.
Do not perform this manoeuvre near the to the ground.
Deep Stall / Parachutal Stall
It is possible for gliders to resume their normal shape on a very
slow release of the B-lines, but carry on descending vertically and
without full forward motion.
It is unlikely to happen on any OZONE glider, but should it hap-
pen, your first reaction should be to fully raise both brakes and the
glider should 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 air-
speed) 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!
