Armstrong MA (Mid Aspect) V1 MA1225: a legacy wing, no longer in Armstrong's current range. 1,225 cm², 935 mm span, aspect ratio 7.10. 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.

The brand's published aspect ratio agrees with its own span and area (span² ÷ area) to within 5%, so the figure is confirmed.
