Hello Bharath

By far IIT kharagpur and IIT Bombay are considered the best aeronautics engineering colleges according to multiple surveys. Then ofcourse are iit Kanpur and IIT Madras. To be true prospect of aeronautics and aerospace in India is pretty low if you are not in one of the above mentioned institution and even if one manages to get through with jee and get into these institution only the top rung of students get good jobs. Ofcourse there is a lot of prospect in the aerospace engineering field as far as research and development is considered abroad and in india too in institution like ISRO . Hindustan aeronautics in India recruits aeronautic engineer. I would also like to mention if u would like to study aeronautics or aerospace engineering. And you do a good bit of research on this.
