Billiebob is correct in stating that a current MIR is q requirement to commence a type rating for a multi crew a/c. Interestingly it doesn't have to be current till the end of the typr course in that it can expire after the commencement of the course.
Fuelxfeed, not sure if MCC is required to commence type course as many TRTOs offer MCC included with type??
