Etymologically, the entry records: Borrowed from French plan (“flat surface, ground plot, map”), from Latin plānus. Some sources also argue for influence or alteration of French plant, from plantar, from Latin plantāre (“set, fix in place”). Compare plane, plain. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is plan, spelled P-L-A-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
