Definition#

The empennage (tail assembly) consists of the horizontal stabilizer with its elevator, and the vertical stabilizer (fin) with its rudder. Some aircraft use a stabilator (all-moving horizontal tail) instead of a fixed stabilizer and elevator.

Why It Matters Operationally#

The empennage provides static and dynamic stability in pitch and yaw. Its size and position relative to the CG determine the aircraft's handling qualities.
