How is the rudder actuated?

• A. Electrically
• B. Mechanically
• C. Hydraulically
• D. Aerodynamically

Answer: (C)

The rudder is actuated hydraulically, which is a key feature in the A320 aircraft's design. This hydraulic actuation system allows for effective control of the aircraft's yaw axis by moving the rudder in response to pilot inputs or automatic flight control systems. The hydraulic system provides the necessary force to position the rudder rapidly and accurately, ensuring precise maneuvers during flight. In most commercial jet transports, including the A320, hydraulic systems are utilized because they can generate higher forces with less weight and complexity compared to mechanical systems. Additionally, hydraulic systems can enhance performance, particularly at high speeds and during significant maneuvers where rapid changes in control surface position are required to maintain aircraft stability and control. Understanding the rudder's hydraulic actuation is essential for grasping how modern aircraft systems are designed for reliability and effectiveness in various flight conditions.
