PARSEC is a parameterization (Sobieczky, 1998, Mukesh and Selvakumar, 2010) scheme which uses the unknown linear combination of base functions to express the shape of the airfoil.It uses twelve different geometrical characteristics of the airfoil to solve a system of linear equations by which it can express the airfoil geometry.

The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). It is approximately equal to the mean distance between the Earth and Sun. The Sun is at a distance of 8.3 kiloparsecs from the centre of the Milky Way system. In the Milky Way Galaxy, wherein Earth is located, distances to remote stars are measured in terms of kiloparsecs (1 kiloparsec 1,000 parsecs).
