04 Setting up the Core 3
and test-flying
Before the first flight
WARNING
A specialist must test-fly and inspect the
paraglider before your first flight. The
test-flight must be recorded on the
paraglider information label.
During production, the Core 3 goes through
several quality control checks before finally
undergoing an exact type certification test.
Conformity with the reference specimen is
checked and certified before the glider is
delivered to the customer. Extreme care is
taken in the manufacture of all patterns,
lines and riser lengths. They show a high
level of precision and should not be altered
under any circumstances.
WARNING
Any changes or improper repairs to this
paraglider shall render invalid the
certification and warranty.
Adjusting the main brake lines
The Core 3 is delivered ex factory with a
brake adjustment marked which complies
with the test sample and which should not
be altered. This adjustment will allow you to
steer and land the paraglider almost without
delay.
The main brake lines must be checked by
an expert before the test flight, and must be
fastened so that the mark is visible approx.
5mm above the knot.
Factory setting
Correctly installed brake lines have about
10cm of feed. This is how far you must pull
down the brakes before the trailing edge of
the paraglider starts to move downwards
and begins to brake. Note that the brake
cascades already cause drag by their
aerodynamic resistance.
Modern gliders such as the Core 3 have
less tolerance with regard to adjustment of
the brake lines. It is therefore normally not
necessary to alter the length.
If you do nevertheless adjust the brakes,
under no circumstances should you go
above or below the tolerance levels given in
the Maintenance and Service book.
Incorrect adjustment
If the brake lines are too long, the paraglider
reacts slowly and is difficult to land. The
brake lines can be adjusted during flight by
wrapping them around your hands which will
improve the flight characteristics. Adjust the
brake lines to the correct length after you
have landed. Changes to the braking
distance should always be made in small
increments of no more than 2 to 3cm and
must be tested on a training slope. The left
and right brakes must be adjusted
symmetrically.
If the brakes are shortened, care must be
taken that the paraglider is not slowed down
in trim and accelerated flight because of the
brake lines being too short. Safety issues
may arise and performance and launch
behaviour may deteriorate if the brake lines
are shortened too much.
