above your head release the risers and keep the handles in your hands, then do 180º turn
to face the slope, run and take off.
IMPORTANT: Never take off when the glider is not fully inflated or falls toward one side.
> fly with the C risers
In order to obtain a better flight control, anticipate collapses, keep a higher speed and better
efficiency flight in turbulent air without using the brakes you can control the wing with the
C risers. In order to pilot with the C risers keep the handles and pull the C risers.
With the C risers you can actively fly through turbulent air. When the leading edge open-
ings transmits a lack of pressure apply some input with the C risers in order to keep the
mouths open. The amount of the input to apply varies with the turbulence but it must
be smooth to avoid any pitch or surge forward of the canopy.
This method is right for normal air, not strong turbulences. In the case of being hit by
strong turbulence keep using actively the brakes to maintain the wing open.
IMPORTANT: Never take off when the glider is not fully inflated or falls toward one side.
> landing
Choose a large field clear of all obstructions
& in a clean laminar airflow with an extra
in security in case of making mistakes. Always face the wind when landing.
A different technique is needed for different wind strengths. Every landing should be
judged differently even if it’s your local site.
On final approach the pilot should have hands up (keeping a feel on the wing in case of
unexpected turbulence) so the glider has energy for a flare. In light or nil winds the pilot
will need a committed symmetric flare at around one meter above the ground. When the
wind is strong avoid too much braking to avoid a dangerous situation. Once in the
ground with strong winds run toward the canopy and pull the C risers to avoid being
pulled by the wind.
You must avoid the canopy to fall on its leading edge since the pressure will not escape
and you can brake cells and ribs.
> possible flight incidences in turbulent air
-- asymmetrical tuck/collapse
An asymmetric tuck / collapse is when part (one side) of the wing ( say 20% or even any-
thing up to 90% of the span) tucks or collapses, usually induced by turbulence but some-
times also trough poor pilot control in turns and wing-overs.
