B-Line Stall - Nova TATTOO Manuel D'exploitation

In order to increase the sink rate as well as the horizontal speed, this manoeu-
vre should be done together with use of the speed system. Apply speed system
after big ears are induced (step into the pedal before you grab the outer A-
risers).
Big ears substantially reduces the risk of canopy stability problems in turbulent
air.
To exit the Big ears release the A-risers. The canopy does not always self-re-
cover. If not, or to quicken the recovery, the pilot gently brakes the glider.

B-line stall:

To induce a B-line stall symmetrically pull down both B-risers by about 20cm.
The airflow over the top surface is almost fully detached and the canopy enters
a vertical descent flight mode without forward movement.
Further pulling of the B-risers reduces the surface area more and increases the
sink rate. (up to 10 m/s)
Be careful, pulling too far may cause a frontal horseshoe to form.
To exit from this flight mode release the B-risers quickly (1 sec).
The canopy surges forward reattaching airflow over the top surface again and
resumes normal flight.
When the B-risers are released, the brakes should not be activated. This will
give the canopy the possibility to gain speed and resume normal flight.
The NOVA TATTOO generally is self recovering from B-line stall. If the canopy
remains in a parachutal stall, it is sufficient to gently push both A risers forward
or to push the accelerator.
WARNING: IF BRAKES ARE APPLIED WHILE IN A PARACHUTAL STALL,
THE GLIDER MAY SUDDENLY ENTER A FULL STALL.
In close proximity to the ground, due to the forward surging pendulum effect, a
recovery may be more dangerous than a hard landing in parachutal. If landing
in a parachutal stall, the pilot should prepare for a hard landing and make a
parachute roll landing.
ALL RAPID DESCENT TECHNIQUES SHOULD FIRST BE PRACTISED IN
CALM AIR AND WITH SUFFICIENT HEIGHT SO THE PILOT CAN USE THEM
FULL STALLS AND SPINS ARE TO BE AVOIDED AS WRONG RECOVERY
PROCEDURES, IRRESPECTIVE OF THE TYPE OF PARAGLIDER, MAY
BY FAR THE BEST TECHNIQUE IS TO FLY CORRECTLY AND SAFELY, SO
YOU NEVER HAVE TO DESCEND RAPIDLY!
IN EMERGENCY SITUATIONS!
HAVE DANGEROUS CONSEQUENCES!
