How does the digital fly-by-wire system improve aircraft safety?

The digital fly-by-wire system enhances aircraft safety primarily by providing faster response times and minimizing the chances of mechanical failures. This system replaces traditional mechanical flight controls with electronic interfaces, meaning that pilot inputs are translated into commands that can be processed by the aircraft's computers.

This transition to a digital system results in quicker and more precise control of the aircraft, allowing it to respond more effectively to pilot commands and external flying conditions. Furthermore, because there are fewer mechanical components that can wear out, become jammed, or fail, the likelihood of a mechanical failure causing an accident is significantly reduced. The overall reliability of the flight control systems is therefore improved, which contributes to greater safety during all phases of flight.

Other choices, while they might contribute to safety in broader contexts, do not directly address the key improvements brought by the digital fly-by-wire technology itself. Redundant control systems, for example, are indeed an important aspect of aircraft design, but the main advantage of fly-by-wire technology lies in its ability to provide rapid and reliable control responses, which is a more direct link to enhanced safety.
