RAPID DESCENTS
BIG EARS
You can deflate both wingtips simultaneously pulling down the A' risers (red
ribbon) by approximately 50 cm.
It is important not to let off the brake toggles while entering the Big Ears
manoeuvre. When folded, paraglider will maintain straight course with an
increased sink rate (up to 5 m/sec). The canopy remains controllable with
weight shifting. On releasing the A' risers canopy usually reinflates
spontaneously, or can be aided by a long pump until the tips get clear.
Due to possibility of entering parachutal stall it is advisable to apply
speedbar after folding the wingtips, in order to diminish AoA.
CAUTION: See Parachutal Stall section.
SPIRAL DIVE
You can reach highest sink rates by spiralling. Significant G-forces, however,
make it difficult to sustain a spiral dive for long, as it places high loads on the
pilot and glider which can lead even to a blackout. Never do this manoeuvre
in turbulence or at too high bank angles, that is make sure that sink speed
never exceeds 16 m/s. If the wing does not recover after releasing the brake,
you must support it applying outer brake.
NEVER DO BIG EARS IN A SPIRAL!
Tests have proven that loads in a dive can be even higher than those
used in certification tests (i.e. 8 G), which could result in structural
failure of the glider, as smaller number of lines is taking these high
loads.
B-STALL
To enter a B-stall simultaneously pull down both B-risers (yellow) by 10-15
cm. The wing will collapse on entire span along B-row, airflow over the top
surface will break and canopy surface will be decreased. Forward movement
will be almost completely gone. Avoid pulling of the B-risers deeper, as it
increases the wing instability. If the canopy forms a horseshoe with wingtips
in front of the pilot, gently apply brakes to recover.
To exit B-stall both risers should be released in a smooth and decisive
manner. On quick and symmetrical releasing B-lines airflow reinstates and
the wing surges forward, returning to normal flight.
