Armstrong HS (High Speed) HS1250: a legacy wing, no longer in Armstrong's current range. 1,250 cm², 830 mm span, aspect ratio 5.51. The current wings that match it within ±5% area and ±8% aspect ratio, from Armstrong'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.
