If even been told by senior pilots that not even the multi-engine rating is required as long as you have the frozen atpl .. because they say that the company is going to type rate you anyway so you get the multi rating at the same time..
As LFS said, this is not true, you must have a Multi Engine IR.
Im finishing my Frozen ATPL exams soon and now im wondering whats next?
Certainly not the MCC. The MCC is the last thing that you will need to do, prior to starting a type rating.
