Which Airbus aircraft pioneered the use of digital fly-by-wire control systems and was a short to medium range narrow-body aircraft?

The Airbus aircraft that pioneered the use of digital fly-by-wire control systems is the A320. The term "fly-by-wire" refers to a system where electronic signals control the aircraft's flight control surfaces, rather than traditional mechanical linkages. The A320 was groundbreaking as it was the first commercial jetliner to introduce this technology, which greatly enhances the aircraft's control precision and safety.

The A320's fly-by-wire system allows for advanced features such as envelope protection, which prevents the aircraft from exceeding its operational limits, and it enhances pilot workload management through automation. As a short to medium range narrow-body aircraft, the A320 is designed for efficiency in both performance and operating costs, making it a popular choice among airlines for various routes. Its role in advancing aviation technology has set a precedent that many subsequent aircraft, including later Airbus models and other manufacturers’ jets, have adopted.
