B-line Stall
Grasp the B risers at the quick links, and ease them down symmetrically. Do not
snatch them down.
The paraglider will enter a B-line stall and feel to drop backwards before the pilot
stabilises underneath the wing. The descent rate increases to 6 - 8 m/s.
To exit the B-line stall raise both hands together in a single, positive movement so
that the risers are at normal full extension again.
On releasing the B-risers, your AROLLA 2 should return immediately to normal flight.
An adjustment error, control error or certain aerological conditions may lead to a
prolonged deep stall phase. A push on the speed bar should initiate rapid exit from
the B-line stall state.
If the speed bar is not connected, pulling on the A-risers by 4–5 cm will have the
same result.
CAUTION : Unlike big ears and spiral dives (see above) a glider in a B-line stall is in a
true stalled position. For this reason, a B-line stall should never be performed close
to the ground
Performance & Use of Brakes
AROLLA 2‘s best glide is at trim speed (no brakes) – about 37-38 km/h. The
minimum sink rate is achieved by applying approx. 15% brake.
When using more than 30% brake the aerodynamics and the performance of the
glider deteriorate and the brake pressure rapidly increases.
With extremely high brake pressure there is a great risk of an impending stall which
occurs at full brake travel (100% brake).
In normal flying conditions the optimum brake position, in terms of performance and
safety, is within the top third of the braking range.
Use of Speed Bar
Your AROLLA 2 is equipped with a highly efficient speed system. For fitting and
positioning of the accelerator system and speed bar, consult the instructions provided
by your harness manufacturer.
Before each take-off check that the entire accelerator system works freely and that
the lines are long enough to prevent the speed bar from being activated involuntarily
in flight (lines too short).
If the harness is fitted with a front mounted reserve, the speed bar lines must pass
under the reserve container and the reserve bridle so that it can be deployed
correctly.
Use of the speed bar increases the maximum speed of the paraglider by up to 30%
of the trim speed. Whilst the AROLLA 2 remains stable at full speed, no paraglider is
