The aspect ratio of the aileron is the ratio of its span to its mean chord. It provides an indication of the aileron’s elongation or how long and slender it is. A higher aspect ratio aileron may generate less drag but could be more susceptible to flutter. Aspect ratio is calculated as: Aileron Span (b_aileron)
