Using the paraglider
Delivery
Before delivery every ADVANCE paraglider has to be flown by the
dealer and checked for correct settings and trim. When this has been
done the dealer enters the date of the first flight on the label attached
to a centre rib. This entry, together with a completed warranty form,
will ensure that defects in the product attributable to manufacturing
faults are covered by the ADVANCE warranty. See Warranty in the
section «Service».
The SIGMA 8 comes with a backpack, an inner bag, a compression
strap, a repair kit, speed bar with lines, a mini windsock in the canopy
colours and a booklet called ‘Getting started’.
Basic settings
The basic SIGMA 8 set-up at delivery is the original trim setting that
the ADVANCE test team have found to be best; and the glider was
certified in this condition. Any personal alteration or modification to
the paraglider - for example, changing the line lengths or fitting differ-
ent risers or quick links by the owner - will result in invalidation of the
certification. See section «Certification».
Adjusting the brake lines
The length of the brake lines is set at the factory so that the trailing
edge is not braked (is crease-free) when brakes are fully released in
fully accelerated flight. This setting should be kept as a matter of prin-
ciple.
If the length of the brake lines has to be readjusted there must be 8
cm of slack (free travel) between the brakes free position and the first
effect of brake on the trailing edge in unaccelerated flight. We recom-
mend that the brake handles are secured with a bowline knot. See
the attached illustration, page 35.
Speed system with SPI
The SIGMA 8 is a cross country glider designed for accelerated flight
in bumpy air. Accelerated flight plays an ever more important role for
the recreational pilot, and a high average speed is a decisive factor
in the success of long flights. This requires an ongoing review of the
choice of speed to fly between thermals, based on the current head-
wind, expected next climb quality and the effect of sinking air – and
the right decision will achieve the best possible glide, or the shortest
time to cloudbase. The SPI is a very important feature of the
SIGMA 8.
