i'm one of those old chaps to whom empennage sounds right along with other funny french words like aileron that flight used to italicize but am aware it sounds a bit antiquated to many so a move with a redirect would be fine i do think it should change to something close to the meaning of empennage though so i'd go for tail surfaces as none of the three suggestions made above focuses on these tail aircraft includes things like tailwhhels and bumpers tail parachutes and tail gunners etc as do the others tail surfaces would also need no bracketed dab
