6. INCIDENTS

6.1 Asymmetric or Frontal (Symmetric)
Collapses
Despite tests showing that Flux 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 lean-
ing 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.
• If flying at maximum speed (trimmers and accelerator) Flux
will exit the collapse with larger amounts of inertia. The
accelerator should immediately be released and the pilot
should be ready to anticipate the resulting forward pitch of
the wing and damp any surge appropriately with the use of
the brakes to avoid a further collapse of the leading edge.

6.2 Stalls

Certain pilot behaviour or weather conditions can cause a full
stall. This is a serious deviation from normal flight and can be
difficult to manage. If a stall occurs at less than 100 m above
the ground, throw your reserve parachute.

Main Causes of a Full Stall:
• Poorly timed or excessive use of the brakes when the air
speed of the wing is reduced (e. g. when coming out of a
spiral or speeding up after a B-line stall).
Rain-induced deep or Full stall:
• A soaked or heavily drenched leading edge (from rain or a
cloud) can result in a full stall or Deep stall due to uneven
airflow over the leading edge as a result of rain drops and
an increase of weight to the wing. Reported cases of this
phenomenon are linked to high levels of porosity in the
glider's fabric. Whatever the cause, a stall can be either
symmetrical or asymmetric (a spin). In both cases the
brake line travel becomes very short and even small input
may suddenly induce an airflow separation; in some cases
even a gust or a sudden thermal may change the angle
of incidence enough to cause the deep stall. If you find
yourself flying in unavoidable rain we strongly recommend
that you avoid any sudden movements or radical brake line
input, that you do not pull Big Ears or B-stall, and that you
steer clear of turbulence and avoid a deep flare on landing.
In both cases the pilot has two possible courses of action:
• If the full stall happens above 100 m it is strongly recom-
mended to initiate standard stall recovery assuming the
pilot is familiar with the process (i.e. a complete execution
of the full stall, stabilization of the wing and progressive
lifting of the hands to resume normal flight).
• If the full stall happens below 100 m or if the pilot is unfa-
miliar with stall recovery the reserve parachute should be
deployed immediately
6.3 Brake line malfunction
If a brake line or pulley breaks it is possible to turn Flux using
the tip steering controls. Alternatively, the D risers (rear risers)
may also be used to turn. In this case the movements should
be finely controlled as the deformation of the wing due to the
traction on the D risers is greater than that produced by using
the brakes.

example sand, stones or animal or vegetable matter which
may eventually decay. Twigs, sand, pebbles, etc. damage
tissue in successive folds, and organic debris of vegetable
or animal origin (insects) can promote mould growth. Flux
is fitted with debris release slots at the wing tips. Debris
can be shaken from the closed cells through to the wing
tip and the release slot opened to remove particles. Check
that you reseal the debris release slot when completed.
