Does CPL Theory + IR Theory = ATPL Theory?
 

Hi,

Supposing I wanted to become an airline piliot one day!!

If I were to do the CPL Theory, then at a later date do the IR Theory (and the associated flying, to get these ratings), would the CPL/IR (+MCC?) transform into a fATPL?

...or, as I think might be the case, would I end up still having to do some or all of the ATPL Theory, in order to get an ATPL?

The simple answer is NO.

There is CPL theory and ATPL theory, they are two different (but not too different) theory papers. You don't need to do the CPL theory first (anymore).

If you don't plan on getting an IR, and just want to become an FI, do the CPL.

Otherwise, there is no point, and you may as well just do the ATPL theory. The exams remain valid sop long as you renew your IR at least every 7 years (don't let it lapse by more than 5 mind you, or you'll be paying the CAA another test visit).

Your choice
