Is there any way to get financial aid to become pilot in India or abroad? Is there any country which charges less to become pilot then in India?

Cost of pilot training is less in many countries like S. Africa, Philippines, USA etc. However, the costs as per advertisement usually includes flying charges only. You have to pay extra for food, accommodation, to & for travel, local transportation etc. which costs a lot in USA, Canada, UK etc. So make sure that the package includes all of these, before signing up. Flight charges, documentation fees etc. are usually excluded from the package and so due attention should be given for that.

While considering cost of flying, make sure that you are comparing packages in India and abroad with similar aircraft with similar features. Charges differ heavily depending on features like conventional & glass cockpit, variant or model of aircraft, age of aircraft, airport used (prefer busy airports with passenger transit over private airstrips), simulator type and fuel used (diesels are less expensive).

Number of hours required to achieve licenses may differ slightly from country to country. So make sure that you are paying for 200 hours of flying, which is mandatory as per Indian standard. If you can get license in 150 hours in the country you chose you will have to fly another 50 hours to complete 200 hours of flight time, when trying to convert license to Indian CPL. If you no longer wish to work in India, it will be okay to go with the standards of the other country.
