FlyingForFun,
I have no idea why flyer4life thinks you must pass the ATPL exams.
I wasn't thinking, I was stating a fact. Check the pre-requisites for a first multi-pilot type rating in
LASORS . The ATPL theory syllabus includes areas the CPL/IR syllabus lacks. One such area is Performance A, which a type rating course would assume a trainee knows all about.
Since a 737 is a multi-engine aircraft, you must have a multi-engine rating.
Only a multi IR. You don't need a valid multi-engine class rating (MEP) as this applies only to single-pilot light pistons. Of course, you do need the MEP to get the multi IR in the first place. The reason an MEP is not listed in the pre-requisites is because if your MEP has lapsed, you can still start a type rating course providing you have a current multi IR.
