A and B + C’ risers are gradually shortened. C-riser retains its original
dimensions.
CAUTION: An improperly adjusted speed system renders the
certification invalid!
Speed system adjustment
Most of modern harnesses are equipped with special speed system pulleys
and sometimes even its own integrated speedbar. If it's not the case, first
you need to have some pulleys attached (at best sewn into harness) in such
a way that will allow the pilot maximize the output of his/her legs with correct
power vector, without effect of pushing the harness back.
The speed system cord must be firmly attached (with bowline or other non-
slipping knot) to the speed bar. The other end of the cord must be ran
upward through the harness pulleys, to be finished with hooks or small
carabiners. Overall length of speed system cord should allow pilot to put
his/her feet easily into the bar when in flight, and yet should be short enough
to cover the full speed range.
Make sure that both cords on the speed bar are equal, as even slight
difference can result in constant turning of the paraglider. Test your speed
system thoroughly on the ground before flying with it!
The maximum action is reached when speed system pulleys touch.
Speed system operation
Before take-off attach paraglider risers to the harness with main carabiners.
Then connect speed system cords with hooks or quick-links. Before
launching make sure that speed system is not tangled and runs freely.
To use the speed system simply place your feet on the speed bar and push
forward in a horizontal plane. If you notice loss of pressure on the bar, it can
be a sign of imminent frontal collapse. In this case release the bar
immediately. Watch out for such things - quick wits can spare you most
collapses and in general you will increase your awareness of the air around
you.
Speed system operation diminishes your paraglider's angle of attack, so that
its airspeed is increased. Yet simultaneously canopy becomes less stable -
that's why you should avoid using speedsystem in turbulent conditions,
close to the ground or near other airspace users!
Do not use speed system during extreme manoeuvres! If the canopy does
collapse, release the speed bar immediately and correct the situation as
usual.
