are made with stronger (slighly heavier grade) nylon of to prevent aerofoil deformation,
even after several years of intensive use. Rib (cell wall) reinforcements are made of
Dacron
310-

gr. Line attachment points are made of polyester.
--lines
The lines are made of Superaramid kevlar covered with a polyester sheath for protection
against wear, UV and abrasion. The riser karabiners, also called "Maillons Rapide", are
made with stainless steel of. Risers are made of pre-stretched polyester.
> certification
The ZEPHYR is a paraglider of a intermediate level that has passed the tests of the EN.
level B with great success. This glider has successfully passed the EN shock test with a
weight equal to the maximum total (all up) take-off weight. This means that the
paraglider is certified to resist to a load of 8 (eight) times the gravitational acceleration
(8 G´s).
As regards the weight range of the glider, ALWAYS be certain that you are within the
correct weight range of the glider. To fly under-weight or over-weight can adversely
affect the stability of the ZEPHYR and flown as such it will no longer be certified.

&
the speed
system
Best glide in nil wind, and still air, is
obtained at “trim” speed- that is brakes
fully released and no accelerator (speed
bar) applied. It is always best to fly with
a light pressure on the brakes, keeping a
“feel” on the wing in case of unexpected
turbulence.
When flying into (against the) wind a
better glide can be obtained by using the
speed system. The following is rough
guide line as to how much to apply.
-With around 10 km/h (6,2 Mph) of head
wind, best glide is obtained with 25%
accelerator applied.-With around 10
km/h of head wind, best glide is obtained
with 25% accelerator.
-With around 15-25 km/h of head wind,
best glide is obtained with 50
%
accelerator.
