04 Setting up the TWIN
RS and test-flying
Before the first flight
WARNING
A specialist must test-fly and inspect the
glider before your first flight. The test-flight
must be recorded on the paraglider
information label.
The TWIN RS goes through several quality
control checks during production before
finally undergoing a detailed type
certification test. Conformity with the
certified reference model 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 which have not been
approved or improper repairs to this
paraglider render invalid the certification
and warranty.
Adjusting the main brake lines
The TWIN RS is delivered ex factory with a
brake adjustment which is marked on the
brake lines and conforms to the certified test
sample.
This adjustment allows the pilot to steer and
land the glider almost without delay.
The main brake lines are checked by the
specialist before the test flight, and must be
fastened so that the mark is visible about
5mm above the knot.
The brake line length must not be
shortened.
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
.
The TWIN RS comes factory-set for optimal
handling so it is therefore not normally
necessary to alter the brake length.
However, you are able to lengthen the brake
setting if necessary to suit your personal
requirements.
If the brake adjustment is altered, under no
circumstances should it exceed or fall below
the tolerance levels given in the
Maintenance and Service Book for the
TWIN RS.
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 then being too short. Safety
issues may arise and performance and
launch behaviour may deteriorate if the
brake lines are shortened too much
