Page 4: Thank You For Flying Advance
Thank you for flying ADVANCE Congratulations on your choice of SIGMA 8 - a quality product from ADVANCE. We are sure that you will spend many rewarding hours in the air with it. The user manual is an important part of the glider. Here you will find instructions and important information about safety, care of the glider and maintenance, and that’s why we recommend that you read this document carefully before your first flight. -

Other important details Efficient and smooth 2-phase speed system with SPI Thanks to its 3 line levels and the choice of profile the SIGMA 8 can be PERFORMING very efficiently accelerated with little effort. In addition the SIGMA 8 has a variable ratio speed system. This means that the speed bar travel and pressure can be changed to suit the user’s anatomy: smooth, 3:1 ratio when the legs are bent, and efficient, more direct 2:1 with outstretched legs. - Page 8 ADVANCE Standards ADVANCE pays a lot of attention to small details. Sewn-in tension straps improve the wing’s stability, and the distinctive winglets reduce induced drag (vortex-effect). The Smart Sail System aligns the mate- rial at the leading edge in the best direction to match the loads in this area, and a strong, specially impregnated fabric is used here to im- prove the life of the wing.

The red markers on the speed sys- tem enable a precise speed bar position to be set to suit the in-fl ight situation.
