RAPID DESCENTS
Spiral Dive:
Spiral dives as explained previously have a rapid descent rate, however,
the very high G-forces make it difficult to sustain a spiral dive for long
and it can place high loads on the pilot, the passenger and glider. Never
do these in turbulence or at too high bank angles. If done in strong winds
the pilot may drift off course.
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.
Warning
:
•
Never do big ears in a spiral!
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.
5m/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-Stall:
To induce a B-line-stall pull both B-risers simultaneously by 50 - 60cm.
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. 10m/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.
Warning
:
•
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!
