The distinction does not mean that Aeronautical Engineering graduates cannot work in aerospace-related organisations or that Aerospace Engineering graduates cannot work with aircraft. There is considerable overlap between the two fields. The major difference is the breadth of the curriculum and the student's preferred area of specialisation.
B.Tech Aerospace vs Aeronautical Engineering After 12th: Eligibility
Students generally enter these programmes after completing 12th Science with Physics, Chemistry and Mathematics (PCM).
According to WIIA's published information, its B.Tech Aerospace Engineering eligibility includes 10+2 with Physics, Mathematics and Chemistry, a qualifying aggregate of at least 50%, entrance qualification and medical fitness. Candidates with relevant engineering or science diplomas may also be eligible under the stated criteria.
For B.Tech Aeronautical Engineering, WIIA lists 10+2 with PCM from a recognised board or a three-year engineering diploma as an eligibility route, subject to the programme's admission requirements.
