Congratulations on the purchase of your new paraglider
The TEMPEST is a very versatile wing and has been designed for all types of recreational flying, from long cross country and competition flying, to relaxing smooth evening
and morning soaring flights.
We strongly recommend that before you even unfold the TEMPEST you read this manual
carefully in order to be aware of any general limitations, performance characteristics,
take off and flight characteristics, landing procedures, dealing with emergency situations
and general maintenance.
We appreciate your feedback, so please send us your comments, positive or negative, in
regard to the
Windtech
range.
You are the best feedback and support for future products, and please remember that we
are always happy to give you any help & advice.

> warning & liability
This manual has been created to give the pilot help and hints to help with the correct
operation of this wing. By no means is this a substitute of a training course, or appropriate experience gained with years and hours of airtime, nor is this manual intended to
give pilot´s knowledge regarding flight safety.
Windtech
assumes that the purchasing pilot has the appropriate pilot's licence, has
taken a training course, and has the suitable ability and enough experience to safely fly
the TEMPEST.
This manual cannot be used for operational purposes. The flight log & registration card
must be filled and stamped by the dealer & returned to
Windtech
in order to claim on
the guarantee.
The use of this paraglider is entirely at the user's own risk. As with any adventure sport
paragliding is a high risk activity-especially without taking the appropriate precautions therefore it must be absolutely understood that
Windtech
& the dealer do not accept
any responsibility for accidents, losses, injuries, direct or indirect damage following the
use or misuse of this product
> desing materials
The TEMPEST is a DHV 2 glider that offers total security, along with beautiful handling
& incredible performance. The performance is very high due to a well-defined structure
with 61 cells, with an internal structure comprised of diagonals of different types, depending on the width of the cell and an optimized line layout to reduce the overall number
of lines. Due to the special SSS system of the leading edge with floating reinforcements,
so that the leading edge maintains totally solid when accelerated. The new profile provides security, performance and efficient turning behaviour.

-- cloth
The upper and lower panels are made with 45 gr. Porcher Marine Skytex nylon. The ribs
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-
180 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 TEMPEST is
a paraglider of a intermediate level that has passed the tests of the DHV
level 2 with great success. This glider has successfully passed the DHV 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 TEMPEST &
flown as such it will no longer be certified.
> best glide
& 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 speed system to apply:
-With around 10 km/h of head wind, best
glide is obtained with 25% accelerator.
-With around 15-25 km/h of head wind,
8
best glide is obtained with 50% accelerator.
-With around +25 km/h 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 TEMPEST is a DHV 2 accelerated but using the accelerator system close to the
ground is not advisable & it should be released as soon as turbulent air is encountered.
Note that the glide angle is not affected by the wing loading, but that the security is.
Always fly a glider that is the correct size for you, and remember that if your flying weight is
below the stated minimum, the speed range will diminish and inflation problems may appear.
Also the handling will degrade in turbulent conditions, and it will be easier to sustain collapses. If your flying weight is above the stipulated weight range, this will result in a higher minimum speed and faster landing speed and the stall speed of the glider will also be higher.
The TEMPEST has a brake of medium
weight resistance (from 1.5 to 3 kg of
force) for the majority of manoeuvres.
To reach the stall (never recommended
on any type of paraglider), requires
more than 9kg.
> flight
Each and every glider has a checklist
note passed though our strict quality
control in the factory. This included line
measurement, ground inflation and
flight testing. Contact your distributor
for more information about this, and if
your glider has not been pre-inflated
ask him to do so for you. Every glider
should be test flow before it is sold.
Note that each glider has a unique sticker attached to the centre airfoil with
the serial number, type of glider, size
and weight range.
We recommend that your first flight on your new glider be on a gentle slope in calm conditions before making your any further higher flights, just to check the glider and for you
to get used to flying it. We also recommended that you use a harness that has an ABS
cross strap system.
For you own safety, we strongly recommend the use of back protection, helmet and
Wind-SOS reserve.
