Let's consider flat wrapping is to be used for lofting. If wing has taper ratio of 0.4, span of 26.6ft and root chord Cr is 76in then, find the area to be covered by flat wrapping.

The area of a tapered wing can be calculated using the formula: Area = (Cr + Ct) * span / 2, where Cr is the root chord, Ct is the tip chord, and the span is the distance from one wingtip to the other. Given a taper ratio of 0.4, the tip chord (Ct) can be calculated as 0.4 * Cr. With Cr = 76 inches, Ct = 0.4 * 76 = 30.4 inches. Converting Cr and Ct to feet (since 1 foot = 12 inches), Cr = 76 / 12 = 6.33 feet, Ct = 30.4 / 12 = 2.53 feet. Plugging these values into the area formula gives: Area = (6.33 + 2.53) * 26.6 / 2 = 117.8 square feet, which rounds to 118 square feet.
