What is the benefit of having a stabilator instead of a traditional elevator?

A stabilator is a type of control surface that combines the functionality of an elevator and a horizontal stabilizer into a single moving surface. The primary benefit of having a stabilator instead of a traditional elevator lies in its ability to provide more effective pitch control, especially at high speeds.

When the stabilator moves, it alters both the surface area and the aerodynamic attitude of the tail section, which enhances the overall effectiveness of the pitch control during various phases of flight, such as take-off, landing, and maneuvers requiring rapid changes in pitch attitude. This design can lead to better responsiveness and control authority, particularly in situations where aerodynamic forces are greatest, making it easier for pilots to manage the aircraft's attitude and respond to dynamic changes in flight conditions.

Other aspects of the stabilator's design, such as being less prone to aerodynamic stall compared to a traditional elevator, can also contribute to improved handling characteristics in larger aircraft.
