AFS Silk Front Wing (V1) 1050: a legacy wing, no longer in AFS's current range. 1,050 cm², 916 mm span, aspect ratio 8.00. The current wings that match it within ±5% area and ±8% aspect ratio, from AFS'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.
