We derive a necessary and sufficient condition for orbital flatness of single-input control systems. We show that a single-input control system S is orbitally fat if and only if the codistribution naturally associated with S is the Goursat structure. To find a new time and a fat output, one needs to transform the codistribution naturally associated with S into the Goursat normal form. Algorithms for constructing such a transformation are well known, so our condition is constructive and provides a systematic way to find a new time and a fat output. An illustrative example is given.
