[1] Angle of attack is the angle between the body's reference line and the oncoming flow.

For a constant-chord wing of chord c and span b, the aspect ratio is given by: If the wing is swept, c is measured parallel to the direction of forward flight. For most wings the length of the chord is not a constant but varies along the wing, so the aspect ratio AR is defined as the square of the wingspan b divided by the wing area S. In symbols, .
