Accelerator System

For better penetration in headwinds you can fly faster by using the
accelerator system. Using the accelerator decreases the angle of
attack and can make the glider more likely to collapse. Therefore
using the accelerator near the ground should be avoided.
Setting up the accelerator system
To set up an accelerator on the ground ask a friend to pull your ris -
ers into their in-flight position whilst you sit in your harness. Now
adjust the length of the line so that the main bar sits just beneath
your seat. You should now be able to hook your heel in to the sec -
ondary (lower) loop of the accelerator.
The accelerator must be slack enough to ensure that the front risers
are not pulled down in normal flight, but not so long that it is impos -
sible to use the full speed range of the Vulcan.
Extending the secondary (lower) loop of the accelerator fully will take
the Vulcan through approximately half its accelerated speed range.
This is as much speed as you will normally need in general flight.
Should you need even more speed you should hook your feet on to
the upper bar which you can then extend until the pulleys on the ris -
ers touch.
Once set up test the full range of the accelerator in calm flying con -
ditions. Ensure that both risers are pulled evenly during operation.
Fine-tuning can be completed when you are back on the ground.
WARNING
We advise you not to use the accelerator when flying in tur -
bulence. Inexperienced pilots are recommended not to use
the accelerator system until they are fully accustomed to the
glider. Although all gliders are designed and tested with an
accelerator system most experienced pilots hardly ever use
the full speed range, especially in turbulent conditions.

Using your Vulcan

Practice Flights

To familiarise yourself with the glider it is a good idea to perform
practice inflations and small flights on a training hill. This will enable
you to set up your equipment correctly.
Lay out the Vulcan on its top surface in a pronounced arc, with the
centre of the wing higher than the tips. Lay out the lines one side at
a time. Hold up the risers and starting with the brake lines, pull all
lines clear. Repeat with the D, C, B and A lines, laying the checked
lines on top of the previous set, and making sure no lines are tan-
gled, knotted or snagged. Mirror the process on the other side.

Take-off check list:

1. Check reserve parachute - pin in and handle secure
2. Helmet on and fastened
3. All harness buckles closed - check leg-loops again
4. Karabiners and maillons tight
5. Lines cleared
6. Leading edge open
7. Aligned directly into wind
8. Airspace and visibility clear

Launching

Your OZONE Vulcan will launch with either the forward or reverse
techniques.
OZONE gliders have split A risers. The outer A-line is attached to a
mini-riser to assist the pulling of big-ears. You should use all the A-
risers during launch.
Before any launch you should lay out the Vulcan as you did for your
practice flights and get in to your harness. Once clipped in, stand
central to the wing to ensure an even and progressive inflation.
Forward Launch - Nil to Light winds
When the wind is right, move forward, your lines should become tight
within one or two steps. The Vulcan will immediately start to inflate.
You should maintain a constant pressure on the risers until the wing
is overhead.
