Pilot Training

In India, the cost of training is between 25 to 40 Lacs. In US, it costs around 25 to 30 Lacs all included.
For Airline job, you have to further do a type rating which costs an additional 16-24 lacs. (I did TR after getting the job, but I had to pay for it)
So, yes it is expensive. Job opportunities come up with time but are very limited and highly competitive. There are about 100 airline openings for freshers a year in India and there are already 6000+ unemployed CPL holders with around 500+ type rated guys. The starting salary varies from 1 lakh to 2.5 Lacs per month in airlines. But, getting that opportunity takes time and a lot of effort.
Even if you do all the right things, you might still be left out because of the market dynamics at play (airline industry in heavy losses). For example, jet airways conducted an exam for all CPL holders in 2011 Feb., then group discussions and interviews in 2013 and they are yet to give joining to all the students (had to stop fleet expansion because of losses). Students are still waiting for a call from them. These are beyond anyone's control and waiting for an airline job even after 4-years of clearing the entrance exam exacts a heavy toll financially. The banks don't have that much patience and you have to start to repay those high EMI's.
Corporates hire only experienced people or those with military flying background. Regional aviation is still in its nascent stages in India.
That leaves flying clubs, where the starting salaries can be abysmally low. Ground instructors being paid 5000 INR per month.
For becoming a flying instructor, you have to do an additional training after CPL which costs additional time (6-9months) and money- 12 Lacs+. Even after which flying clubs offer a salary starting at only 25000 - 35000 INR per month. It is all demand and supply in the market, leading to these low wages.
The only safe option would be to join Indigo Cadet Pilot Programme. You have a selection process after which selected cadets get a job contact with indigo. Yes, a airline job assurance before you even start flying. But, it is expensive at 36-40 Lacs for CPL and 21-22 Lacs for type rating.
My advice: Before doing CPL, be financially prepared for the eventuality of a long wait for job. But, with time and effort, you can definitely make it to an airline. All the best.

You must complete class XII under the 10+2 system or its equivalent with a minimum of 50 per cent marks in maths and physics. You must be at least 16 years of age to be eligible for a Student Pilot License, 17 for a Private Pilot License, and 18 for a Commercial Pilot License.
To become a pilot you need a Bachelor's degree in aircraft operations, aviation, aeronautical engineering, or a related field. In addition, you will complete up to two months of ground training and need more than 1,500 hours of flight experience.
A college degree helps to demonstrate to the airline that you will be capable of completing their education program. Look around your local area for a good flight school and flight instructor to begin working on your private pilot certificate. The FAA minimum flight time is 40 hours, but the average is around 60.

To become a commercial pilot:
1. You need to first possess a student pilot license. You must be over 17 years of age and have completed 12th in Science (Physics and mathematics) with 50%.
2. Your vision in one eye must be perfect. In general medical terminology, it is called 6/6 eyesight. In the other eye, you could have an imperfection of 6/9, which must be correctable to 6/6.
3. General physical fitness is mandatory. You must be free of any disease that can hamper normal function.
4. You need to register at a flying club which is recognised by Directorate General of Civil Aviation (DGCA), Government of India.
5. Next is private pilot license which includes sixty hours of flying. A commercial pilot license may be obtained only after a PPL and 250 hours of flying.
Some of the institutes offering commercial pilot training are:
1. Academy of Carver Aviation Private Limited, Pune.
2. All India Institute of Aeronautics, Dehradun.
3. Center for Civil Aviation Training (CCAT), Delhi.
4. Glorietta Aviation, Ghaziabad.
5. Fly Wings Aviation Private Limited, Mumbai.

Hi,
Pilot training (commercial pilot license):
Duration: 1 year (approx.)
Eligibility:
10+2 or its equivalent with a minimum of 50% marks in mathematics and physics. If you don't have physics and maths in 10+2 you have an option of doing these two subjects from National Institute of Open Schoolings On-Demand Examinations and can still start your Pilot training course. Visit www.nios.ac.in for details.
At least 16 years of age to start pilot training. Vision in one eye must be perfect. (6/6 eyesight) In the other eye, you could have an imperfection of 6/9, which must be correctable to 6/6. You must be free of any disease that can hamper normal function.

DGCA is an Indian govt. the regulatory body, and has no authority over any course taught outside of India. However, some pilot training colleges may claim that their course is approved by DGCA, which is technically a marketing strategy. Here is how -
DGCA requires you to have completed a certain number of flight hours during the course, along with certain licenses and ratings. After you gain these, you can convert your licenses and ratings upon return to India. Most of the pilot courses comply with these requirements, as the requirements to be a pilot are uniform across countries and authorities.
So here is what you can do. Research on the DGCA requirements. Then check the course curriculum at the college of your choice. See if the number of flight hours and other requirements is the same or not. In any case of confusion, write to the admission office of the college. They will be happy to answer any questions about their course curriculum and will be able to explain international recognition part as well.
