A line of a map projection along which the principal scale is conserved. This is the case of the meridians in normal cylindric and conic equidistant projections, the great circles that irradiate from the centre in azimuthal equidistant projections and also all parallels in Bonne and normal ortographic projections. Note that an equidistant line is always a line of constant scale but not necessarily a conformal line.
