What device is commonly used by the pilot in a fly-by-wire system to enter commands?

In a fly-by-wire system, a joystick is commonly used by the pilot to enter commands. This system replaces traditional mechanical controls with electronic interfaces, allowing for more precise handling and flight control. The joystick provides a modern and intuitive way for pilots to maneuver the aircraft, offering enhanced responsiveness and adaptability in various flight conditions.

In contrast, while the throttle, yoke, and pedals are essential components of an aircraft's control set, they serve different functions. The throttle is primarily responsible for controlling engine power and speed, the yoke is typically used for controlling pitch and roll along the aircraft's axes, and pedals are used for controlling yaw and navigating turns. However, in fly-by-wire systems, the joystick allows for a more advanced and integrated approach to pilot commands, facilitating improved aircraft performance and safety.
