Accelerating; Landing; Asymmetric And Frontal Collapses - Airdesign Susi 2 Betriebshandbuch Und Serviceheft

The aim of active flying is to keep the glider above the pilot's head in all situations by
responding correctly to the glider's movements using the brakes and weight shift.
When entering a strong or rough thermal it is important that the glider is not too far back or
able to enter a dynamic stall. To avoid this, it is often helpful to release the brakes slightly
when entering, which gives the glider a little more speed. Equally, when exiting a strong climb
it may be necessary to brake more to prevent the glider from diving forward.

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.
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.
The high trim-speeds are no problem at all for landing. The glider can be slowed down by
pulling a little brake and will still maintain enough energy for the flare. If you miss the point of
flare, the glider generally maintains enough power to make a second flare.
The biggest size (20) does not need to be flared excessively. The smaller sizes should be flared
for a perfect landing. Be aware that on the smallest size (14) the brake travel is short and a fast
full pull on the brakes makes the glider stall quite suddenly.
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.
The SuSi airfoil is based on 2-line technology and therefore designed to be highly collapse
resistant. The A-attachment points are placed far behind the leading edge.
We do not recommend making intentional collapses on the SuSi. If you do want to test
collapses, start by pulling very gently on the A-lines and with sufficient ground clearance. Do
