Caution: Do not fly spiral dives or aggressive changes of di-
rection with big ears applied: the raised wing loading carried
by fewer lines can damage the glider.
B-Stall
The B Stall puts high stresses on the material and the profile shape of
the glider. We recommend that you do not fly B stalls regularly, even
this manoeuvre does not present special difficulties to the SIGMA 8.
Stalling
One-sided stall (spin)
The SIGMA 8 warns you of an impending spin by an increasing pres-
sure from the brake in a turn. If you maintain the brake differential on
the paraglider, you will then notice a marked reduction in brake pres-
sure on the inside of the turn. In this situation, you must fully release
the brake line immediately, enabling the SIGMA 8 to return to normal
flight of its own accord.
If you were to fully stall a wing the glider will fall into a spin/negative
rotation. Depending on the situation from which you let it fly again, it
can then shoot forward and collapse. While it is shooting forward the
canopy can be stabilised by careful braking. Normal flight may then
be resumed without further collapse.
Flying a spin is not recommended although this manoeuvre does not
present any particular difficulties with the SIGMA 8.
Tip: Basically you should immediately release both brakes
completely in all out-of-control flight situations, but especially
at the onset of spinning behaviour.
Full stall
The initiation of a full stall is effected by progressive symmetrical pull-
ing of both brakes. This reduces the forward speed. The airflow and
wind noise decrease. On reaching the stalling speed, the paraglid-
er initially goes into a brief deep-stall phase. Further pulling on the
brakes will cause the airflow to break away completely and the pa-
raglider then tips backwards into a full stall. When recovering from
this manoeuvre, the canopy must be «preinflated» over its complete
wingspan. To achieve this, the brake lines should be released slowly
at first, and then only released fully after preinflation.
The SIGMA 8 canopy turns out to be very manageable while stalling,
as well as during full stall recovery. If, however, a wingtip does cravat,
