The Deck is delivered together with a backpack, inner bag,
glider strap, Triple Seven T-shirt and USB key with this manual.
Assembly
Before you rush to the first take-off we recommend you take your
time to unpack and test your equipment on a training slope. In
this way you will have time and will not be distracted or rushed
to prepare your equipment, and you will be able to do your first
pre-flight check properly.
The place should be flat, free of obstacles, and with light wind.
This will enable you to nicely inflate the wing and also familiarize
yourself with it while ground handling. Every glider has to be
checked by a Triple Seven dealer, however, as a pilot you want to
do a proper pre-flight check yourself.
Firstly, prepare and spread out the glider like you would normally
do. While you are spreading out and walking along the glider,
observe the fabric material for any abnormalities. When you are
done with the inspection of the canopy, grab the risers and spread
the lines, check if the risers and maillons (carabiners) are properly
closed. Identify and disentangle the A1, A2, B, C risers
and the lines including the brake lines. Connect the risers’ main
attachment points correctly to the harness, watch for any twists
and make sure that the main carabiners are properly closed.
Harness
The Deck has passed EN-A certification testing using a GH - ABS
type harness. This certification allows the Deck to be flown with
most of the harnesses on the market, but keep in mind that the
change of a harness greatly influences the feeling of the glider,
depending on the effectiveness of the harness weight shift. Check
with the harness manufacturer or with your instructor whether
your harness is of the proper type.
The length of the harness chest strap affects the distance between
the main carabiners and the wing’s handling as well as your stability
in the harness. Tightening the chest strap increases your stability,
but greatly increases the risk of twisting after a collapse. A tight
setting also increases the tendency to maintain a deep spiral. As a
rule of thumb, a more opened chest strap gives you more feedback
from the glider, which is good for your climbing efficiency and
increases safety in a flying incident. But we strongly recommend
adjusting the length of the harness chest strap according to the
lengths used during certification. This setting varies according to
the harness size from 42cm to 50cm.
Check the settings used during testing under the certification
specimen section.We recommend that your first flight with the
Deck is not also with a new harness. Another rule of thumb is
if you want to experience the feeling of new equipment, change
only one part of equipment at a time.
Accelerator settings
The Deck speed system increases the speed of the glider by
11km/h with the accelerator at full travel, from trim speed at 38km/h
to full speed at 49km/h.
Before attaching the accelerator system to the Deck risers, check
that the speed system inside your harness is correctly routed and
that all pulleys are set correctly. Make sure there are no knots or
other obstacles that might make the accelerator get stuck during
usage.
The length of the speed bar lines should be adjusted on the ground
so that your legs are fully extended at the point of full accelerator
travel. While setting the speed line lengths make sure they are long
enough, so that the speed system does not accelerate the glider
by itself. If in doubt how to properly set the accelerator system,
please consult your instructor or Triple Seven dealer.
Brakes’ adjustments
The length of the brake lines has already been adjusted by the
manufacturer and is the same as used during the certification test
flights. The length is set and fine-tuned during the development of
the glider, therefore generally there should be no need to adjust
them. We recommend flying this setting for a while, and you can
still change it afterwards if you wish to do so. If you change the
length of the brakes, do it in a step by step process of 2 cm at
a time. Bear in mind that if you make the brake lines too short,
they might be applied unintentionally while the speed system is
being used.
