How does it work?
The speed system utilizes a 3 to 1 pulley mechanism which results in
shortening the A- and B- risers as described above.
How to use it?
Before launch, attach the paraglider's risers to the harness with the main
carabiners. Then attach the "Brummel-hook" on the end of each speed
system cord to the Brummel hook on the end of the cord which runs
through the 2 pulleys on the A risers.
Ensure that the speed system is untangled and operates freely 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 the speed system immediately.
With this "feeling" you may actually prevent most collapses from happen-
ing while using the speed system. If a collapse still happens, release the
speed system immediately and correct the collapse as described in
"Collapses" section.
BE CAREFUL!
WHEN USING THE SPEEDSYSTEM THE ANGLE OF ATTACK IS
LOWERED, THUS AIRSPEED IS INCREASING, AND THE CANOPY IS
DESTABILIZING.
THEREFORE DO NOT USE THE SPEEDSYSTEM IN TURBULENT
CONDITIONS, CLOSE TO THE GROUND OR NEAR OTHER AIR-
SPACE USERS!
NEVER RELEASE THE BRAKE HANDLES!
DON'T APPLY BRAKE WHEN FULLY ACCELERATED!
SHOULD YOU HAVE A COLLAPSE, RELEASE THE SPEED SYSTEM
IMMEDIATELY, TO ENABLE THE GLIDER TO RETURN TO STANDARD
TRIM AND THEN RECOVER WITH CORRECT PILOT INPUT AS IN A
NORMAL COLLAPSE.
DO NOT USE THE SPEEDSYSTEM IN ANY EXTREME MANOEUVRES!
