Aeronautical Engineering

Based on your qualification and area of interests, it is advised that you opt for general management programme for aerospace and aviation executives (GMAE). GMAE is a part-time certificate programme for working professionals from the aerospace and aviation sector. The programme is being offered by IIMB in partnership with Toulouse Business School, France. Participants who successfully complete the GMAE programme are eligible to pursue the aerospace MBA being offered by TBS.
Aerospace MBA is a two-year programme delivered by both faculty members from TBS and IIMB together with industry experts from Aeronautics, Aviation, Space & Defence. Kindly refer this link:

Aerospace and automotive are two major manufacturing industries - also old industries born over a century ago; they have drastically evolved in the past 30 years in terms of product performance, leveraging high technologies and significantly reducing time-to-market. Both industries rely on rigorous quality requirements, advanced materials, electronics and embedded systems, mechanical components, engines, structures, (.) as well as robust New Product Introduction (NPI) and enabling Product Life-cycle Management (PLM).
Aerospace is a generic term that includes commercial aircraft, planes and helicopters, military and defence, ground equipment and space.
The aerospace industry has a strong certification and compliance requirement, with consequences on development cost and technology solutions. The automotive industry requires perhaps less formal processes, though there is a significant focus on compliance and regulations.
Overall both have a great scope in varied sector domains.

Marine engineering is a branch of engineering which deals with boats, ships, oil rigs and any other marine vessel or structure, but also encompasses oceanographic engineering. It is niche branch with high paying salaries but full of challenges to have work life balance. Job opportunities for Marine engineering graduates are in shipping and ship build industry.
Aeronautical Engineering also is a niche which prepares students for designing and building aircraft and spacecraft. Aeronautical engineers handle design, manufacturing and maintenance of aircraft, helicopters & UAV. There are lots of good career opportunities on completion of Aeronautical engineering. You can join DRDO/ ISRO/ Aviation manufacturing or its ancillary units/ Airlines/ Air Force/ Educational Institutes/ R&D Units/ IT, etc.
Both the branches are equally good. You must choose a branch based on your interest to succeed in the professional life. Marine jobs are full of challenges, therefore, you are advised to choose this profession if you are ready to accept its challenges willingly.
