Dear,

The minimum eligibility for the SPL(student pilot license) is 16 years of age and matriculation . An oral examination has to be taken in subjects related to aviation. One needs to acquire a private pilot license (PPL) before starting to fly. Flying includes overall 60 hours of flying with cross-country and solo flying. And also you have to pass theoretical examinations in subjects like air regulations, air navigations , aviation meteorology and aircraft engines. so after you complete your engineering you can get admission in some pilot training institutes

If we talk about money then let's first see where we need to spend our money in order to get a job in airline,

1. Commercial pilot training- 30 lacs
2. Type rating- 20 lacs
3. Airline training- 15 lacs
4. ATPL(airline transport pilot licence)- 5 lacs

So, after seeing the break up we can sum up the cost to be between 70–80 lacs. Above mentioned fees are just rough ideas it might be more or less

Hope this helps!
