Hello all, I meet all of the aeronautical experience requirements for the ATP certificate. I passed the ATP written test 12 months ago. My question is, if I take the ATP single-engine land practical test within the next 12 months, but want or need an ATP multi-engine land certificate in the future will I have to take the ATP written test again? I've looked over the regs and I am unclear about this. Is there someone with experience in this area who could shed some light on this situation? Thank you.
