History

Etymology

From plane (adjective) + sailing (noun), a variant of plain sailing probably by analogy with plane chart (“(nautical) chart representing the earth in which lines of latitude and longitude are respectively shown as parallel straight lines”) or plane scale (“(chiefly nautical, obsolete) scale or ruler with markings used for calculations, especially for navigation”).
