How is the rudder controlled?

• A. Fly-by-wire and hydraulically actuated
• B. Mechanical linkage
• C. Hydraulic only
• D. Pneumatic and hydraulic

Answer: (A)

Rudder control on this aircraft is provided by a fly-by-wire system with hydraulic actuators. When you press the rudder pedals, the input isn’t sent as a direct mechanical link to the rudder. Instead, the pedals feed electrical signals into the flight control computer, which applies the appropriate control laws and determines the commanded rudder deflection. That command is then sent to hydraulic actuators that physically move the rudder surface. The hydraulic system provides the necessary force and is designed with redundant channels for safety. Pneumatic or purely mechanical linkages aren’t used as the primary means of rudder actuation here.
