The B.Sc. Aeronautical Science course is designed as a comprehensive 3-year program, and it is not usually possible to complete it in less time. The curriculum is carefully structured to cover a wide range of subjects related to aeronautical science, with each semester building on the knowledge from the previous one.
Additionally, practical sessions, lab work, and industry training require sufficient time to complete. Accelerating the program would likely compromise the quality of education and training that students receive, making it unlikely for institutions to offer shorter durations.
