B-stall
In the B-stall, a stall is provoked and the
paraglider sinks vertically with a sink
rate of approx. 8 m/s. The B-stall is
suitable when there is an average
ascent rate and little wind.
Starting the manoeuvre
Grasp both of the B-risers on the
mallions at the coloured mark. Pull both
B-risers evenly down until the airflow is
broken and the wing goes completely
into vertical descent flight mode. The B-
risers should then be held in this
position to ensure a gentle descent.
TIP
Pull down the B-risers only until
there is no airflow. If they are pulled
down any further, the glider could go
into a horseshoe.
Check before and during the B-stall
that the airspace beneath you is
clear.
Recovery
Return the B-risers quickly and evenly
into their normal position. The glider
may go into a deep stall if they are
released too slowly or into a negative
spin if not released symmetrically. If this
happens, the speed must be increased
using the speed system or by pulling the
A-risers forward.
WARNING
The canopy speeds up after the B-
risers have been released until the
airflow
returns.
Under
no
circumstances should the brakes be
applied at this time.
This manoeuvre should be avoided at
low temperatures. Pilots should be
aware
that
this
considerably
increases the tendency to deep stall.
Big Ears
WARNING
The technique of big ears causes a
higher load for the line groups which
are still weight-bearing. Therefore, do
not fly any extreme manoeuvres with
big ears.
This manoeuvre should be avoided in
low temperatures. Pilots should be
aware that this increases the
tendency to deep stall.
Big ears are the simplest method for
rapid descent and have a sink rate of 3-
5m/s. The advantage of big ears is that
the glider continues to fly straight,
meaning that a danger area can be
avoided. It is even possible to land using
big ears, for example on a top-landing to
compensate for the updraft.
The wing-loading increases by the
reduction in the wing’s surface area,
the wing becomes more stable against
collapses in turbulence. Nevertheless,
the air resistance of the wing also
increases, and it flies more slowly and
closer to the stall limit. To counter this
and to increase the effectiveness of the
sink, the speed bar is generally also
used in combination with big ears.
