Behaviour

DynamicPlus
It's agility lives up to the well-known SIGMA character - it responds to steering inputs directly and with great precision, its "thermal bite" utilises even weak upcurrents to climb effortlessly and facilitates flat turns. The SIGMA 6 responds forgivingly to imprecise manoeuvres.

PerformancePlus
It's more efficient profile and slightly increased aspect ratio pay dividends. With the greater performance compared to its predecessor, the SIGMA 6 has significantly better gliding and climbing characteristics. Whether in trim speed or accelerated, it again sets standards in its category.

SafetyPlus
Even and fast re-inflation without stalling or overshooting - the SIGMA 6 also proves itself as a top-intermediate with the desired perfect take-off characteristics. The high canopy stability with optimised internal wing pressure makes the wing easily controllable and delights pilots with its balanced behaviour in turns.

HandlingPlus
The lower brake pressure compared to the SIGMA 5 makes for sensitive flying. The precise brake travel enables immediate implementation of the commands to act directly, sensitively and meet the expectations of short brake travel.

DesignPlus
The SIGMA 6 offers an aesthetic yet sporty appearance. The new SIGMA graphic at the wingtips rounds off its elegant look and leaves an unmistakable impression. Four selected colour combinations make pilots' hearts beat faster and also address the aspects of maximum safety and longevity.

ConstructionPlus
The adapted line geometry achieves what it sets out to do: reduced air resistance, simplified line control as well as efficient acceleration are the outstanding points. Optimised risers in two different lengths ensure easy and safe handling even when flown by smaller pilots.

Flying Acro with the SIGMA 6

On initial view the SIGMA 6 appears to be a very dynamic but well behaved wing that would suit acro flying purposes.

The development of the wing however had characteristics for cross country and thermal flying in sight. It has been neither structurally strengthened nor tested at higher than usual G loadings.

Naturally you can fly wonderful wing overs and loops with the SIGMA 6. But remember that such manoeuvres stress the wing more and the longevity of the wing is greatly reduced. Obviously greater pilot skill is a pre-requisite for pilots who wish to perform Acro.

IMPORTANT: ADVANCE does not recommend the SIGMA 6 as an Acro glider.

Innovations

Improved risers
With the SIGMA 6, risers are now being offered in two different lengths. For easier and safer handling by smaller pilots, canopy sizes 22 and 26 are being equipped with shorter risers (difference 4 cm) than the canopy sizes 28 and 31. This makes the lines easier to reach when airborne.

Efficient and smooth speed system with SPI
The SIGMA 6 speed system enables an increase in speed of up to 15 km/hr. The system is designed in such a way that on pressing the speed system, the A, B and C levels shorten by different amounts; thus an optimum canopy form is maintained even in accelerated flight.

The system is very smooth in operation thanks to the well designed pulley arrangement. Its effective mode of operation enables an excellent glide performance, even at high speeds.

Speed-Performance-Indicator SPI
A speed/performance scale which is printed on each D riser assists to determine the optimum speed system position. SPI is the link between practise and theory, so you are always flying at the optimum cruising speed !

Line geometry
The line geometry has been refined for the SIGMA 6. An 80-metre reduction in total line material means less resistance, improved line control and effective translation of the speed system to the wing profile.

Certification

Our R & D Team considers the certification tests from the start of the development process. But to be fully satisfied with the wing - behaviour, pleasure, performance - remains our first priority.

All sizes of the SIGMA 6 will be certified according to DHV 2 requirements, with the speed system.
