B-line Stall
Grasp the B risers below the quick links and pull them symmetrically.
The paraglider will stall and drop backwards before stabilizing overhead.
The descent rate increases to 6 - 8 m/s.
In order to release the B-line stall raise both hands together in a single quick
movement. As soon as the B risers are released, FIDES 3 should return
to a normal flight. If the B-line stall is released incorrectly, the paraglider may
remain in a parachute (deep) stall. The recovery of the paraglider could
be then initiated by using the speed bar. In case there is no speed bar, pulling
at the A risers by 4 – 5 cm will bring the same result.
Caution: unlike the big ears and the spiral (see above) when the glider takes
the position of the B-line stall, it is in a stalled state.
6) Performance & Use of Brakes
FIDES 3 best glides at a trim speed (no brakes) – about 37 km/h.
The minimum sink rate is achieved by applying approx. 15% of the brakes.
When using more than 30% of the brakes the aerodynamics
and the performance of the glider are likely to deteriorate and the effort
to maneuver will increase quickly.
In case of extremely high brake pressure there is a great risk of a coming
impending stall which occurs at a full brake travel (100% of the brakes).
In normal flying conditions the optimal position for the brakes, in terms
of performance and safety is within the top third level of the braking range.

7) Use of Speed Bar

FIDES 3 is equipped with a speed system. For fitting and positioning
the speed bar consult the instructions of the harness manufacturer. Before
every take-off check that the speed bar works freely and that the lines
are long enough to ensure that it is not engaged permanently. 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 easily.
Use of the speed bar increases the maximum speed of the paraglider
by up to 30% of the trim speed. However, it does reduce the angle of attack
and therefore there is a risk of a frontal (or asymmetric) collapse. We therefore
do not advise to use the speed bar near the ground or in turbulent air.
8) Asymmetric or Frontal (Symmetric)
Collapses
Despite the tests proved that FIDES 3 recovers on its own after collapses,
active piloting is recommended in case of an asymmetric or frontal collapse.
Active piloting will reduce the loss of altitude and a change of direction.
In case of a frontal (symmetric) collapse:
Bring both brakes down symmetrically to speed up the reopening
of the paraglider, and then raise your hands back up immediately.
In case of an asymmetric collapse:
Keep the paraglider flying straight by leaning in the opposite direction
of the collapse and simultaneously applying the brake on the opposite
side of the collapse.
Speed up the reopening of the closed side by a single, positive input
on the collapsed side.
