QUICK HEIGHT LOSS
3.4.1 BIG EARS
In order to get the big ears you have to pull down the outer lines of the A'
risers (usually distinguished with blue colour) by about 50 cm.
While inducing big ears you should never never let the brakes out of your
hands.
After tucking the tips in, Synthesis Cabrio will continue to fly straight with
increased sink rate (up to 5 m/s). You can steer the wing pretty efficiently with
weight-shifting.
After releasing the lines, the paraglider will usually open up on its own or you
can assist it with a long stroke of the brakes until the tips fill again.
Executing big ears with open trimmers is very difficult due to reflex profile
stabilisation.
CAUTION!
See the PARACHUTAL STALL chapter.
Never try to pull big ears during powered climb, as the increased drag
can lead to increase of the angle of attack and a parachutal stall.
Pulling the ears while climbing is pointless anyway.
3.4.2 SPIRAL DIVE
A spiral is characterised by highest sink rates possible. Significant G-forces,
however, make it difficult to sustain a spiral dive for long, as it can place high
loads on both pilot and glider. Never do this manoeuvre in turbulence or at
too high bank angles. Control the dive and do not exceed 16 m/s sink. If the
dive is not stopping after releasing the brake, assist the glider with the outer
one.
NEVER DO BIG EARS IN A SPIRAL!
In this manoeuvre smaller number of lines is carrying an excessive load
mulitplied by the centrifugal force, what can lead to damage of the lines
or even the paraglider itself (load of a single line can be much higher
than passed in certification trials (i.e. 8 G).
3.4.3 B-STALL
To enter a B-stall, simultaneously pull down both B-risers (red tape) by 10 -
15 cm. The wing will collapse across the entire span along its B-row, the
airflow over top surface will break and canopy surface will be decreased.
