Be careful not to get below minimum speed, and don’t overreact
with the brakes .
Turning flight
The SIGMA 9 has short and precise brake travel when steering . It
responds very directly and progressively to increasing steering
inputs, as soon as brake line free travel has been taken up . Active
weight shift effectively assists steering . Angle of bank can always
be increased, stabilised or reduced by brake line load .
The SIGMA 9 makes a very agreeable companion in thermals . You
do not have to correct for large pitching movements, and this im-
proves your climbing behaviour – and therefore your performance
– significantly . When thermalling, choose the desired angle of bank
and corresponding radius, and try to let the glider turn steadily at
this attitude . Outside brake should be used to steady the wing tip
and, in particular, control the rate of turn . Anything stronger will
slow the wingtip down and lose the glider’s good steering qualities .
A harness specifically designed to match the flying characteristics
of the SIGMA 9 helps you to initialise and stabilise turns of this
type, which should be as even as possible . See also section
«Suitable harnesses» .
Caution: To keep good manoeuvrability make sure to fly your
SIGMA 9 with enough airspeed while turning in thermals –
not too much outside brake .
Tip: If a brake line breaks you can steer the SIGMA 9 using
the C risers .
Accelerated flight
The SIGMA 9 wing remains extremely stable even in accelerated
flight . However, paragliders operate at a lower angle of attack while
flying at their higher speeds, and the degree of stability is gene-
rally reduced . The higher aerodynamic forces involved at higher
airspeeds mean that a collapse can be more dynamic (see also
section «Collapses») .
When encountering severe turbulence while flying accelerated
release the speedbar fully before applying the necessary stabilising
brake . The SIGMA 9’s high degree of structural stability allows
it to be flown in normally turbulent air while accelerated . Active
speedbar should be employed for adjusting angle of attack under
these conditions, instead of brake . Pitch attitude disturbances can
be minimised in this way, and optimal glide performance can be
maintained . See also section
