Section 5
Flying the APUS RS
TIP
The outer wing tip may collapse during
the spiral dive although this is no cause
for concern. It can be avoided by lightly
braking on the outside. Release the
brakes carefully.
Recovery
Recover from the spiral dive slowly and
steadily over several turns. The inside
brakes are gradually released. If the brakes
are released too quickly, the increased
speed can cause the wing to climb, become
unsettled or partly collapse. Recovery can
be assisted by braking lightly on the outside.
DANGER
At a high sink rate (above 14 m/s) it may
be necessary to brake the outside half of
the wing and/or to use weight-shifting to
recover from the spiral.
Furthermore, for exiting the manoeuvre,
several turns with a corresponding loss of
altitude may be required.
DANGER
You must
immediately
deploy your
reserve if you lose control of the glider
and the sink rate and find yourself in a
stable spiral.
The spiral may lead to loads and/or
disturbance to consciousness which
prevent later deployment of your reserve.
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.
