B-line Stall
Grasp the B risers near the quick links, hands on the Yellow sections, 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
APOLLO 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.
6) Performance & use of brakes
APOLLO's best glide is at trim speed (no brakes) – about 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.

7) use of Speed bar

Your APOLLO 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.
APOLLO´s LEO system allows the wing to have a highly tensioned leading
edge at accelerated speeds, offering good levels of deflation resistance
and added glide performance. Whilst this offers improved deflation
resistance, no paraglider is immune from deflations in certain conditions
and the deflation point can be sudden when flying at high speed. Use of
the speed system does reduce the angle of attack and therefore there is
an increased risk of a frontal (or asymmetric) collapse. For this reason we
do not advise use of the speed bar near to the ground or in turbulent air.
8) Asymmetric or Frontal (Symmetric)
Collapses
Despite tests showing that APOLLO recovers spontaneously after
collapses, active piloting is recommended in the event of an asymmetric
or frontal collapse. Active piloting will reduce the loss of altitude and a
change of direction.
In the event of a frontal (symmetric) collapse:
 Before automatic reopening occurs, bring both brakes down swiftly
& symmetrically to speed up reopening of the leading edge, then
immediately bring your hands back up to normal flying position.
In the event of an asymmetric collapse:
 Keep the paraglider flying as straight as possible by leaning away from
the collapsed side and applying sufficient (just enough, not too much)
brake to maintain course.
 Speed up the reopening of the closed side by a single, positive input on
the collapsed side & repeat if necessary.
