Iam doing my diploma in mechanical 3rd year, am i eligible to join CPL (commercial pilot license) directly or should i obtain SPL&PPL b4?

Dear Abdul, You are eligible to join CPL course as minimum eligibility is 10+2 with physics and maths. There is no need to do SPL and PPL separately as it is among the stages of getting the CPL itself. You can visit www.igiaindia.in for detailed information.
