The Airbus A320 program is one of the most successful commercial aircraft programs in the history of aviation. This thesis offers a comprehensive examination of the program. Trough the history and context, with a particular focus on the significant turning points in its evolution is also discussed in this study. The fly-by-wire technology, composites, and sophisticated aerodynamics are only some of the breakthroughs and technologies that are investigated in this research. In the thesis, the difficulties in engineering that arose throughout the production of the airplane are analysed, as are the strategies that were utilized to find answers to those difficulties. Further discussion analyses the topics such as the utilization of modern materials and its impact on the aviation industry, including its economic benefits. In conclusion, the thesis offers an assessment of both the present standing of the A320 program and its potential in the years to come. This thesis, in its whole, makes a contribution to a deeper understanding of the A320 program and the impact it has had on the aviation industry.
