Spiral Dives

If you turn your Vibe in a series of tightening 360's it will enter a spi-
ral 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 Vibe will first turn
almost 360 degrees before it drops in to the spiral. Once in the spi-
ral 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 these high speeds and G-forces can be
disorientating, so pay particular attention to your altitude.
To exit the spiral dive, slowly release the inside brake and apply a
small amount of outside brake. As the Vibe decelerates allow it to
continue to turn until enough energy is lost for it to return to level
flight without an excessive climb and surge.
Spiral dives with sink rates over 8 m/s are possible, but should be
avoided. They are dangerous and put unnecessary strain on the glid -
er.
WARNING: Spiral dives cause disorientation and need time
and height to recover. Do not perform this manoeuvre near
the ground.
Landing
The Vibe shows no unusual landing characteristics.
General Landing Tips
Always set up your landing early, give yourself plenty of options and
a safe margin for error.
Once below 30 metres avoid turning tightly as the glider will have to
dive to accelerate back to normal flight. If you are at altitude, or if
you hit sink, this could mean you hit the ground harder than neces -
sary.
Instead, allow the glider to fly at full speed for your final descent until
you are around 1 metre above the ground. Apply the brakes slowly
and progressively to slow the glider down until the glider stalls and
you are able to step on to the ground.
Be careful not to flare too hard at full speed as the glider might climb
again before stalling. If the glider does begin to climb, ease off the
brakes until it stops climbing, then flare again, but slower this time.
In light winds you need a strong, long and progressive flair 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.
In strong winds you need to turn towards the glider the second your
feet touch the ground. Once facing the wing pull smoothly and sym -
metrically down on the brakes to stall the wing. If the glider pulls
you, then run towards it.
If the wind is very strong, and you feel you might be dragged, stall
the glider with the C risers. This stalls the Vibe in a very quick and
controllable way and will drag you less then if you use the brakes.

Modifications

Your Ozone Vibe was designed and trimmed to give the optimum bal-
ance of performance, handling and safety. Any modification means
the glider loses its certification and will also probably be more diffi -
cult to fly. For these reasons, we strongly recommend that you do not
modify the Vibe in any way.

Towing

The OZONE Vibe 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 tow-
ing regulations are observed.
When towing you must be certain that the paraglider is completely
over your head before you start. A towing force greater than 90 KG
is not allowed. In each case the maximum tow force needs to cor-
respond to the body weight of the pilot.
