A B.Sc. in AME (Aircraft Maintenance Engineering) is a 3-year degree program that provides in-depth theoretical knowledge in aircraft systems, maintenance, and repair. It covers subjects like aerodynamics, avionics, and engine mechanics. On the other hand, a License in AME is a certification issued by the DGCA (Directorate General of Civil Aviation) after completing specific practical training and exams. While a B.Sc. in AME provides foundational education, a DGCA license is required to legally work as an AME in India. The license allows you to perform aircraft maintenance professionally.
