Aircraft Maintenance Engineering

Yes, you can get admission. You just need to qualify AIAMEE.

Kindly contact the airline and ask if they provide such facility.

The average salary of an AME certificate holder is INR 20000-30000 per month (in the beginning).

To get the real picture, kindly contact the alumni and current students of the institute.

Those who opted for Physics, Chemistry and Mathematics or Biology in 10+2 examination can pursue this course. A candidate should clear the minimum cut-off marks designated by the respective university.

Aeronautical Engineering is related to design and manufacturing in the aerospace industry and spacecraft industry while aircraft maintenance engineering is basically looking after an aircraft's maintenance and it's operations. Both are different fields and no comparison can be made.

Madras Institute and LPU have the highest placements for aircraft maintenance engineering. You can opt any one of these. It has a good academic reputation with qualified lecturers.

Carver Aviation Academy by this name, the institute is available in Baramati as well as in Mumbai. In Mumbai, the institution offers pilot training as well as aircraft maintenance engineering.

It is indeed very tough to say as to which college offering AME is better than the other. This is so since no independent or unbiased agency has done comparative analysis. Having said this, one must remember the fact that, present situation in India is very good, as far as job opportunities in this sector are concerned and hence this college too would be able to ensure reasonable placements.

PG in engineering after B.Sc. in A.M.E. I must say that you have very good aim. But, I am afraid, it is not feasible. Minimum qualification for getting admission to any PG course in engineering is graduation in engineering and A.M.E. is actually a B.Sc. degree.
