Aviation

If you do B.Sc aviation from institutes like Indira Gandhi Rashtriya Udan academy then you will be hand-picked and considering the course nature, your job is not confined to one geographical location.

The level of competition to become an airline pilot is fierce. It is anticipated that the number of jobs in the aviation industry for airline pilots will grow steadily over the next decade. The number of entrants into this field is also increasing, so it is expected that only the most well-trained pilots will find themselves jobs at high-paying airlines.
All the best!
