Reference Area Origin in Lift Distribution Formulas

Reference Area Origin is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing’s planform area is called the reference wing area. And is denoted by S₀. Reference Area Origin is usually measured using the Square Meter for Area. Note that the value of Reference Area Origin is always positive.
