Calculating the Wing Area for Tapered Wings
To find the area of a tapered wing, use the
formula for a Trapezoid. Find the average chord and multiply it
times the wing span:
Average Chord = (
Root Chord + Tip Chord ) ÷ 2
Wing Area = Wing Span x Average
It does not matter
if a wing sweeps or not. The formula for a tapered wing is used
with no regard for the sweep.
the wing has multiple tapers then calculate each trapezoidal area and
add them together.
