Is aeronautical engineering has a better scope in future?
see in india there is not many colleges where btech in aeronaitical engineering course is available. most of the govt. colleges nits and iits has this courses. so getting a seat in aeronautical engineering is really hard.
now coming to the scope of aeronautical engineering. most of the students of iits or nits go to abroad to do masters on aeronautic or aerospace. it is very difficult to land a job in india after bachelors in engineering. however drdo, isro, hal, aai has some vacancy. but most of the vacancy requires experience. i think you get my point. to land a job from pvt colleges in aeronautics is really tough through. you can check list of pvt colleges in aeronautical engineering from careers360 page.
