B-Line Stall - Nova PHOR2 Betriebshandbuch

48
The NOVA PHOR2 easily tucks the outside wings and enters a stable descent
mode .
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 manoeuvre
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 verti-
cal 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
FULL STALLS AND SPINS ARE TO BE AVOIDED AS WRONG RECOVERY
PROCEDURES, IRRESPECTIVE OF THE TYPE OF PARAGLIDER, MAY HAVE
BY FAR THE BEST TECHNIQUE IS TO FLY CORRECTLY AND SAFELY, SO
YOU NEVER HAVE TO DESCEND RAPIDLY!
FOR ALL EXTREME MANOEUVRES AND RAPID DESCENTS PLEASE
- FIRST PRACTICE MANOEUVRES WITH AN INSTRUCTOR
- BEFORE INDUCING THE MANOEUVRE THE PILOT MUST MAKE SURE
THAT THERE ARE NO OTHER AIR SPACE USERS BELOW HIM!
- DURING THE MANOEUVRE THE PILOT MUST HAVE
IN EMERGENCY SITUATIONS!
DANGEROUS CONSEQUENCES!
NOTE:
DURING SAFETY TRAINING
THE CANOPY WITHIN HIS VIEW!
