Hello aspirant. The first step to become a pilot is you need to have maths or computer science as major in your +2. Then a degree in aviation, aeronautical engineering, aerospace etc, after this slot of series of steps need to be taken. As in, preliminary training, ground training. A course of few months. Then you will be sent to abroad for 2 years to pursue the course. After this, a personal health check up is done, again few courses here. Few written exams, basic training again. Then you will be appointed as 3rd observer. After training you would be copilot and then pilot.

Hope this helps

Regards
