NEVER DO BIG EARS IN A SPIRAL !
DHV-tests have proven that loads can be developed higher than those used in
certification tests, which could result in structural failure of the glider, as less lines
are taking these high loads.
Big ears :
The outer cells of the wing tips may be deflated by pulling down the outer A-lines
through the A2.
Keep hold of the control handles together with the A2-risers.
The canopy remains completely controlable through one sided braking or weight
shift. It maintains straight flight but with an increased sink rate (up to approx. 5
m/sec).
On releasing the A2-risers the canopy usually reinflates by itself or can be aided by
a long pump on the brakes and holding them until tips clear.
B - line - stall :
To induce a B-line-stall pull both B-risers simultaneously by 50 - 60 cm. The airflow
over the top surface is detached and the canopy enters a parachutal-stall without
moving forward.
Further pulling of the B-risers reduces the surface area and increases the sink rate
(to approx. 10 m/sec).
On quickly releasing the B-lines the airflow over the top surface becomes re-
attached and the canopy surges forward to return to normal flight without applying
brakes.
If canopy does not recover see section „Deep Stall“.
If B-risers are pulled too quickly or too far, the canopy can form a frontal
horseshoe. To recover from this, apply both brakes gently to recover.
ALL RAPID DESCENT TECHNIQUES SHOULD BE PRACTISED IN SMOOTH
AIR AND WITH SUFFICIENT HEIGHT SO THAT THEY CAN BE EMPLOYED
WHEN NECESSARY IN EXTREME FLYING CONDITIONS ! FULL STALLS AND
SPINS ARE TO BE AVOIDED AS WRONG RECOVERY 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 !
