of intensive use. Rib (cell wall) reinforcements are made of Dacron 310 &180gr. Line
attachment points are made of polyester.

-- lines

The lines are made of Kevlar covered with polyester sheath for protection against wear,
UV and abrasion. The lower section of the brake lines is made from Dyneema. This mate-
rial is less prone to failure after repeated use through the brake pulleys. The riser kara-
biners, also called quick links, are made with stainless steel of 800 Dan. Risers are made-
of pre-stretched polyester of 900 Dan.

> certification

The IMPULSE is a paraglider of an intermediate level that has passed easily the tests of

the

EN level A. 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).

With regards to the weight range of the glider, ALWAYS be certain that you are within
the correct weight range of the glider. To fly under, or overweight can adversely affect
the stability of the IMPULSE & flown as such will make it no longer a certified glider.

> best glide

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 pres-
sure 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% acceler-
ator applied.

-With around 15-25 km/h (9,3-15,5 Mph) of head wind, best glide is obtained with 50%
accelerator.

-With around +25 km/h (+15,5 Mph) of head wind, best glide is obtained with 75-100%
accelerator.

When flying downwind (wind from behind ) the best glide is obtained between 0% brake
and 10% of brake.

The IMPULSE is a

EN A accelerated but using the accelerator system close to the ground

is not advisable & it should be released as soon as turbulent air is encountered.
