Advance IOTA


ADVANCE launches the new IOTA Series, a High-Level EN B glider for ambitious cross-country pilots. Featuring an optimized, low-weight design, the XC-Intermediate IOTA represents the most accommodating balance between performance and piloting ease within the entire ADVANCE product range. The high performance capabilities of the IOTA open the door to the world of long cross-country flights.

New Semi-Light Category

There is now a new category called “Semi-Light”. Thanks to computationally modeled lightweight-structure design techniques, the IOTA weighs only 4.45kg ( 23m2 size). And yet the IOTA is a robust and durable product thanks to the material choice of Skytex 32 and 38 from Porcher Sport. The low weight of the canopy improves takeoff behavior, considerably increases passive safety, and contributes to direct handling.

Exceptional passive safety

The IOTA features a low minimum flying speed. Approach to the stall is clearly communicated to the pilot via clearly progressive brake pressure. This is all the result of an optimal air intake design. Low IOTA canopy mass means low wing inertia, and an overall compact concept contributes to the reassuring character of the IOTA. All these factors contribute to the IOTA’s high safety level.

Maximum Performance

Detailed simulation and stress analysis enabled us to engineer the double 3D shaping and surface ballooning to the greatest advantage. The result for us; an even smoother wing surface and more shape stability – looked at from every direction. Your result: even more performance. The IOTA’s balanced compactness and a carefully-chosen pitch-stable profile mean that you can always make the most of the wing’s potential – in real-life conditions.

Structural Weight Optimization

A computational analysis of the interior of the glider resulted in a massive reduction of the overall weight. The topology of the lightening holes of the profiles and diagonal ribs was optimized with respect to the operational stresses and forces. The complex structure is initially reminiscent of a block of Swiss cheese. The outcome of this intensive development process is a product which is noticeably lighter and yet still durable, with an unvarying flight behavior over time.

Advanced Air Inlet Design

The unique combination of the ADVANCE semi-circular inlets and Air Scoop Technology enables a significantly lower brake position at stall and considerably larger progressively in brake pressure, yielding a lower spin tendency when turning. The inner pressure remains high even at high angles of attack thanks to the careful design of the air inlets. The overall goal of this optimization of the inner pressure is the improvement of passive safety.

100% Aramid Lines: Special Coating and Workmanship

The IOTA comes 100% equipped with low stretch, unsheathed Aramid lines manufactured by Edelrid. There are no Dyneema lines used at all. Durability and robustness have been maximized thanks to the careful assembly of inner and outer loop reinforcements as well as an elaborate yarn coating. Many years of experience using this top-quality product are evidence that the advantages of using unsheathed Edelrid lines dominate over all alternatives.

Real Tension Control

Keeping a close eye on the forces and strains in the canopy is crucial for having the least amount of wrinkles and the best performance. Our design tools and methods are capable of computing the distribution of forces and strains in the entire canopy. The optimal aeroelastic design, from 3D panel shaping through to ballooning, is achieved in an iterative, computational process. This enables the maximum conversion of theoretical performance into real performance.
