Spiral dive

B-Stall

RAPID DESCENTS

Big Ears

You can deflate both wingtips simultaneously by pulling down the outer A 
lines 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.

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. 

The Freeway enters a spiral easily and it’s really important to learn a spiral 
dive under guidance of a qualified instructor, since exiting the spiral is not 
automatic and requires pilot action.

If the paraglider does not recover after releasing the brake, you must support 
it applying outer brake. Then once the wing exits the spiral dive, you have to 
disperse excessive &energy in one additional turn before returning to normal 
flight.

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). This could result in structural 
failure of the glider, as smaller number of lines is taking those 
increased loads.

To enter a B-stall simultaneously pull down both B-risers (red) 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.
