The pilot keeps the brake handles along with the outside A- lines in his
hands. By braking on one side and shifting weight the canopy remains
steer able.
In order to increase the sink rate as well as the horizontal speed, this
maneuver can be done together with use of the speed system. Apply
speed system after big ears are induced.
Big ears substantially reduces the risk of canopy stability problems in
turbulent air.
To exit the Big ears release the A- lines. The canopy does not always
self-recover. 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
20 cm. 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.
If canopy does not recover apply both brakes gently to recover.
ALL RAPID DESCENT TECHNIQUES SHOULD FIRST BE PRACTISED
IN CALM AIR AND WITH SUFFICIENT HEIGHT SO THE PILOT CAN
USE THEM IN EMERGENCY SITUATIONS!
FULL STALLS AND SPINS ARE TO BE AVOIDED AS WRONG RECOV-
ERY PROCEDURES, IRRESPECTIVE OF THE TYPE OF
PARAGLIDER, MAY HAVE DANGEROUS CONSEQUENCES!
BY FAR THE BEST TECHNIQUE IS TO FLY CORRECTLY AND
SAFELY, SO YOU NEVER HAVE TO DESCEND RAPIDLY!
