Which system primarily uses fiber optic cables for communication between flight controls?

• A. Fly-by-wire systems
• B. Fly-by-light systems
• C. Conventional electrical systems
• D. Hydraulic control systems

Answer: (B)

The correct choice emphasizes the use of fiber optic cables to facilitate communication and control within the avionics of an aircraft. Fly-by-light systems are advanced control mechanisms that replace traditional electrical signals with light signals transmitted through fiber optic cables. This method offers significant advantages, including reduced weight, immunity to electromagnetic interference, and high-speed data transmission. In contrast, fly-by-wire systems primarily rely on electronic signals but may not specifically use fiber optics. Conventional electrical systems depend on copper wiring for communication and control, whereas hydraulic control systems utilize hydraulic fluid under pressure and do not incorporate fiber optics at all. Therefore, the focus on fiber optics distinctly aligns with the operation of fly-by-light systems, highlighting their advanced capabilities in modern aircraft design.
