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.
