it may be necessary to brake more to prevent the glider from diving forward.
g. Accelerating
The speed system on the SuSi comes supplied with ‘quick hooks’ ready to attach to a speed bar
of choice. The complete speed system should be checked to ensure it runs smoothly by
hanging in the harness before flying.
In particular, check that the speed system won’t be engaged when in normal flight.
Unnecessary knots and loops in a speed system are not recommended.
When pushing the speed bar the angle of attack of the glider is reduced. The glider speeds up
but at the same time is more sensitive to deformation.
In spite of the exceptional stability of the SuSi, any accelerated collapse will be more dynamic
than the same event experienced at trim speed and will require quicker reactions to maintain
normal flight.
Always keep both hands on the controls when flying fast or in turbulence and be ready to
release the speed system immediately at the first sign of a collapse.
When flying through strong sink or into a headwind it is useful to fly faster using the speedbar.
Use the speed system carefully when flying close to the terrain and maintain enough height
from the ground or other obstacles to recover in the event of a collapse.
DO NOT BRAKE WHILE FLYING FULLY ACCELERATED – THIS MAY RESULT IN A COLLAPSE OF THE
WING.
h. Landing
The SuSi is despite its high speed easy to land and has good flaring characteristics. When being
high loaded or in nil-wind conditions it is recommended to flare the glider well.
Attention :
After touching down do not allow the glider to dive overhead and fall in front of you. If the
leading edge hits the ground hard the structure of the cell walls may become damaged.
i. Asymmetric and frontal collapses
As with any paraglider collapses can occur. “Active flying” as described in point “f” can help
avoid deformations.
You should always maintain course and direction by weight-shifting away from the collapsed
side. This can be reinforced by applying a small amount of brake on the opposite side to the
deflation. If the collapse stays in, the glider can be re-inflated by pumping the brake on the
collapsed side in a firm and smooth manner. Be aware that the brake travel is shorter when the
glider is collapsed and the glider can stall with less brake input.
If you experience a big collapse while accelerated, the canopy will fall behind the pilot due to
the difference in inertia between the pilot and the canopy. You must wait until you pendulum
back under the canopy before dealing with the deflation. Reacting too early can risk stalling the
glider completely. Release the speed-bar immediately if you have a big collapse during
accelerated flight and, while keeping weight-shift neutral, apply slight brake to the open side.
