Under normal conditions, how are elevators controlled?

• A. Direct mechanical movement of the surface from the control stick
• B. Signals to the IFCMs from the flight control computers
• C. Pneumatic pressure from engine bleed air
• D. Mission computer commands sent to hydraulic actuators

Answer: (B)

Elevators are controlled through signals sent to the Integrated Flight Control Management Systems (IFCMs) from the flight control computers. This method represents a modern approach to flight control, utilizing advanced electronic systems to manage aerodynamic surfaces. The flight control computers process inputs from the pilot via the control stick and then translate these inputs into commands for the IFCMs. This allows for precise and responsive movement of the elevators, which manipulate the aircraft's pitch. This system is advantageous as it improves the control authority and stability of the aircraft, allows for the integration of various flight envelope protections, and facilitates smoother handling characteristics compared to more traditional mechanical systems. It's a crucial element of how modern aircraft are designed to handle flight control, emphasizing reliability and responsiveness.
