WebThe lift from wings is proportional to their area, so the heavier the animal or aircraft the bigger that area must be. The area is the product of the span times the width ( mean chord) of the wing, so either a long, narrow wing … WebApr 25, 2024 · "Chordwise" is parallel to the aircraft's longitudinal axis because that is the way the air flows. Any other angle would not make sense. It might be of interest on some specific airplanes, but otherwise the only thing that matters is the general airflow, which is parallel to the aircraft's longitudinal axis for cruise flight in most any aircraft.
