How is it fitted ?
Most modern harnesses have pulleys attached for speed system fitting.
In case not, it is important to attach pulleys (sewn on tabs) in such a
way that, allows the pilot to maximise the power vector of his / her legs,
without "pushing back“ in the harness.
The speed system cord is firmly attached (use bowline or other nonslip
knot) to the foot stirrup (webbing or alloy bar). The other end of the cord
is run through a pulley on the harness and then in an upward direction,
to be firmly attached to a small carabiner with very strong spring action
(clip), or preferably a quick link with a screw gate. NOTE: a quick link or
clip with very strong spring action is highly recommended, as, when
doing a reverse start, the brake lines may be accidentally “clipped in” to
a carabiner with weak spring action which will obviously cause severe
control problems. The length of the cord leading to the stirrup should be
such, that it is easy to put your feet into the stirrup in flight, and yet short
enough to allow the full speed range. Ensure both cords on the stirrup
are of equal length, to avoid putting a turn in the glider.
Test your speed system for the correct length of cord on the ground first,
with your harness and risers, before flying with it ! The full range is
reached, when the 2 pulleys join together.
How does it work ?
The speed system utilises a pulley mechanism which results in shorten-
ing the risers as described above.
How to use it ?
Before launch, attach risers of paraglider to the harness with main
carabiners. Then attach clip or quick link on end of speed system cord,
to the loop on the end of the cord which runs through the 2 pulleys sewn
on the A risers.
Ensure that the speed system is untangled and runs freely for operation
before flying.
To use the speed system, simply place your feet on the stirrup and push
forward in a horizontal plane. If a loss of back pressure of the stirrup on
your legs is noticed, this is a warning that the canopy is probably about
to collapse. Release the stirrup and thus speed system immediately.
With this "feeling“ you may actually prevent most tucks from happening
while using the speed system. If a tuck (collapse) does still happen,
release speed system immediately and correct collapse as described in
section "Tucks".
