Manuel d'utilisation (pdf) - Advance

A compression strap is sewn between each profile/line attachment point, on the D lines. Thus
the space between each cell remains the same, whether the wing is braked or not, making turning
performance uniform and consistent. There are also some compression straps between
some A, B and C lines, between the profiles which receive lines not linked to the same main
line. The turn performance and coordination of the wing are clearly improved and reach new
levels for a biplace wing.
As usual with ADVANCE gliders, the smallest details were important to us, to give the BI BETA 2
a high class finish :
• all of the sewing and stitching is internal. This gives us our smooth perfect finish.
• the leading and trailing edges are reinforced with a Mylar tape to increase rigidity and to
make them less sensitive to the high tension they are subjected to.
• the winglets on the wing tips are important aerodynamic elements, improving turn precision
and diminishing the wing tip turbulence (vortex effect), and also an ADVANCE signature.
• the lines and risers remain in correct position in the quick links thanks to a well designed
plastic clip.
• the braking is optimized thanks to a system with rings that acts on the wing tip first.
• the brake handles receive a reinforcement that makes them easy to take and comfortable.
They are attached on the risers with a magnetic snaplock.
