The Sirus V3 Atmo runs 9 sizes, 1,150–2,350 cm², and changes proportion as it grows: aspect ratio runs 9.3 at one end of the range to 15.0 at the other, so its sizes differ in shape as well as in area.
Its 1,160 mm span is 5% wider than typical for the area — the median across the 87 current wings within 10% of its size is 1,100 mm.
Closest wings from other brands
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
