Duotone Aero Carve 2.0 D/LAB 650: a legacy wing, no longer in Duotone's current range. 650 cm², 660 mm span, aspect ratio 6.80. The current wings that match it within ±5% area and ±8% aspect ratio, from Duotone's own published specifications.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a match inside the area tolerance may be comparing unlike figures.
