Glide *		8.8 - 9.2

Surface, span and aspect ratio are calculated from the computer and are measured on the axis of the profile.

* The performance data for the glide angle of the SIGMA 6 are dependant upon the position of the pilot, the aerodynamic style of the harness and the type of clothing worn (eg: Speed arms).
