To be a commercial pilot in India, you need to be a 10+2 pass with Physics and Maths in your 12th board exams from a recognised board with a minimum of 55% in Physics, Maths and English.

Next up comes the medicals. Now in order to become a pilot, you should be medically fit. There are 2 tests conducted by DGCA Class 2 and Class 1. If you pass these, you are now good to go to undertake your flying training.

Then, you can enroll yourself onto any flying schools in India approved by DGCA or go abroad and do your training. It's up to you. Once you've got your CPL along with your MEIR, you can look for jobs online in different airlines.

Hope this helps!
