We recommend that you make your first flights with your new glider
in quiet conditions, in a familiar flying area . A few pull-ups at an ea-
sy site will give you confidence in the SIGMA 9’s handling qualities,
from the very beginning .
Takeoff
Before every takeoff carry out the following pre-takeoff checks:
1 . Harness and helmet done up, reserve OK?
2 . Lines free?
3 . Canopy open?
4 . Wind direction and strength assessed?
5 . Airspace and field-of-view clear?
The SIGMA 9 takeoff behaviour is very smooth and easy for both
forward and reverse takeoffs . The canopy inflates quickly and rises
progressively, without hanging back or shooting in front .
Because the SIGMA 9 rises very easily it is very important to match
the pull-up impulse to the conditions . This means:
§
In a lot of wind and/or on a steep slope the SIGMA 9 needs little
or almost no pull-up impulse .
§
In calm conditions and/or flat land a relaxed pull-up makes
sense .
The SIGMA 9 has split A risers . We recommend that you use all the
A risers for takeoff . The SIGMA 9 inflates reliably from the middle
out, and rises very straight with little exertion .
Tip: Before takeoff get your canopy into the right shape . Do
this while sorting the lines, by pulling the brake lines in until
you have the perfect curved shape .
Info: You can also use the inner A lines for an SIGMA 9
takeoff, but handling is easier using all the A risers .
Takeoff in light wind (forward takeoff )
The SIGMA 9 only needs a moderate pull-up impulse even in a
light wind . It is not necessary to step back and ‘run’ into the lines .
Guide the glider up with pronounced leaning forward, but without
too much of a pull on the A-risers, until the canopy is overhead .
During the pull-up phase any correcting should only be done by
decisive going-under-the-wing, without using the brakes . After any
necessary correcting and a satisfactory visual check a few deter-
mined steps with good leaning forward will achieve lift off, even in
little wind .
Info: A SIGMA 9 takeoff is exceptionally easy to do . Match
your efforts (as described in the section ”Takeoff“ ) to the
wind conditions and takeoff slope .
