Hy rubikscube,
Composite as well you know Air nav+Av met. If you're already holding a foreign CPL and want to convert it to DGCA CPL, you can sit only for composite but not as separate papers. If you sit for the exam before gaining a foreing CPL then you can give air nav and av met separately. You don't have to give composite if you've cleared with both Air Nav and Av met before going abroad for flying.
If you've cleared only, say, air nav or av met(anyone) then you have to redo both as a single paper called Composite again for conversion. So once paper is cleared with DGCA say air nav, av met and air regs before gaining a foreign CPL then you don't have to redo it again for conversion. You can skip composite and air regs for conversion and mind other things.
Now for your situation composite is the only answer. And you also have to give air regs if you've not cleared it in India before flying abroad. So two papers Composite and Air regs.
I am sitting for air nav and air regs in jan attempt. I have cleared av met
in Oct attempt already and I have not started my flying yet.
