What does the term "empennage" refer to in an aircraft?

The term "empennage" refers specifically to the tail assembly of an aircraft. This part of the aircraft plays a crucial role in stability and control. The empennage typically includes key components such as the horizontal stabilizer and vertical stabilizer, which work together to maintain the aircraft's pitch and yaw stability.

The design and configuration of the empennage significantly affect the aerodynamic performance of an aircraft. It helps direct airflow and influences how the aircraft responds to various control inputs from the pilot, ensuring safe and controlled flight. Understanding the function of the empennage is fundamental in aviation, as it contributes to the overall balance and flying characteristics of the aircraft.
