Flying the Sting 2
Section 5

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.
Big Ears
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
’
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.

both outer A-lines downwards. This should
start the manoeuvre by folding down a
sufficiently large part of the wing tips so that
the pilot does not then have to counteract
the tendency to reopen. If the surface area

ears and then pull down and hold the A-
lines a little more firmly.
To make the manoeuvre more stable and
more effective, slightly accelerate the wing
after pulling in the ears.
The brake lines are held steady and the pilot
uses weight-shifting to steer the paraglider.
You can now descend safely on the stable
middle part of the wing. The brakes must not
be shortened during the manoeuvre, e.g. by

grey above the quick link and pull down
firmly.
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.
