One question: In a modular way, the path should be PPL + ATPL theory + CPL&MEP + IR + MCC, am I right?
The IR can be SEP based, or must be MEP as well? I am asking this since I could not really find in JAR-FCL-1 a clear requirement on ME-IR.
If you want to fly for an airline you need the MEIR. Just having a CPL and ME and single engine IR would not be sufficient.
I think it is possible to do a single engine IR and then upgrade this to an MEIR, but that would cost more than just getting the MEIR to begin with.
