Airbus A320

The A320 introduced revolutionary fly-by-wire flight controls to commercial aviation, replacing traditional mechanical linkages with electronic signals. Its side-stick controllers replaced conventional yokes, fundamentally changing how pilots interfaced with the aircraft. The commonality concept allowed pilots to transition between A320 family variants with minimal additional training, creating massive operational efficiencies for airlines. The A320neo variant with new-generation engines became the fastest-selling aircraft in aviation history. The A320 family has become the best-selling single-aisle aircraft ever, competing head-to-head with the Boeing 737.
