How will be the physical fitness to get a pilot training? I'm ready with finance but What should be done for that?

Well you need to have PCM in 10+2 level. Apply for various CPL institutions. Clear the medical tests. I would suggest doing it from Canada as it is cheaper than USA. Please for God's sake don't do it from Philippines as most Aviation Companies have blacklisted most of their institutions for malpract

You are requested to look for detailed guidelines on medical requirements for flight crew issued by DGCA at dgca.nic.in.
