Section 4
Setting up the APUS RS and test-flying
WARNING
If the brake lines are too short, the
following risks could arise:
there could be an early stall
the paraglider does not launch well
and there is a risk of deep stall
the paraglider exhibits dangerous
behaviour in extreme flying
the trailing edge of the paraglider is
braked in accelerated flight which,
in an extreme case, could cause a
frontal collapse
TIP
Environmental conditions can also lead to
the brake lines shortening.
You should therefore check brake line
length regularly, particularly if there is any
change in launch or flight behavior.
Brake knots
The overhand knot and bowline knot shown
below are the most suitable for connecting
the brake line to the brake handle.

Bowline knot
WARNING
Loose, unsuitable or incorrectly tied
brake line knots can cause the main
brake line to loosen and then lead to loss
of control of the glider.
Ensure that only overhand or bowline
knots are used and that they are tied
correctly.
