The term "empennage" refers to the tail section of an aircraft. It plays a crucial role in stabilizing the plane during flight. The empennage typically consists of the horizontal stabilizer, vertical stabilizer, and the control surfaces like the elevator and rudder. These components work together to ensure that the aircraft maintains a steady and controlled flight path. In addition to stability, the empennage helps with maneuverability. The elevator allows the pilot to control the aircraft's pitch, while the rudder helps in steering the plane left or right. Overall, the empennage is essential for safe and efficient flying, making it a vital part of any aircraft's design.
