Horizontal Stabilizer Trim Actuator (HSTA)

As a leader in horizontal stabilizer trim actuation, Woodward equips many civil and military programs. Our HSTA systems enable to keep the aircraft’s attitude stable, by minimizing aerodynamic forces and reducing drag.

Key Features

  • High performance and reliability for a safer flight
  • Balance of aerodynamic forces for a stable flight attitude
  • Reduction of the pilot workload and fuel consumption to fly more efficiently

Keep the Right Attitude

During the flight, the HSTA controls the pitch of the aircraft, while minimizing the pilot workload and fuel consumption, to fly more efficiently. According to the weight, pressures and center of gravity of the plane, the flight control computer sends order to the HSTA via its electronic control unit to adjust the angular positioning of the horizontal stabilizer.
