What is one primary advantage of the Airbus fly-by-wire system?

The primary advantage of the Airbus fly-by-wire system lies in its ability to allow for easier flight control and significantly reduce pilot workload. This advanced technology uses electronic systems to control aircraft flight surfaces instead of traditional mechanical linkages. As a result, pilots receive smooth and responsive handling characteristics, even in complex flight situations.

The system incorporates flight envelope protection, which prevents the aircraft from exceeding its operational limits, thereby enhancing safety and stability. Additionally, this automation can relieve pilots from some routine and manual control tasks, allowing them to focus on strategic decision-making and situational awareness during flight.

While improved passenger comfort and enhanced engine performance are important aspects of modern aircraft design, they are not the direct benefits stemming from the fly-by-wire technology. Likewise, the increase in an aircraft's maximum speed is not a primary function of this system, as its key role is centered around enhancing control and reducing the demands placed on pilots.
