Several factors can affect the duration of a B.Sc. Aeronautical Science course. These include the academic system of the country (semester vs. annual), the inclusion of practical training and internships, and whether the student is enrolled full-time or part-time. In some cases, students may pursue additional certifications in areas like flight training, which can add a year or more to the program. Universities may also offer fast-tracking options, allowing students to finish earlier.
