Hi Seabreeze,
OK but your definitions are a bit compartmentalised I feel.
MCC competencies are made up of both theory and practice. The CASA MCC theorietical competencies are identical to the ATPL HF syllabus competencies. The competencies required to be demonstrated in the flight (usually trained in a simulator) portion of the course is about the application of these competencies both as PF and PM in a multi crew environment.
If the theoretical HF does not mesh completely with airborne competencies, the whole thing is a waste of time.
In EASA land (who invented MCC after all) a person cannot undertake their first multi crew type rating until having completed an MCC. It’s a building block approach. You learn the HF theory, you learn to apply it and then do a type rating using and applying those skills while learning to operate the aircraft. Here in Aus, for reasons best known to CASA, you can buy a type rating in a multi crew aircraft at quite a few sim training providers without completing an MCC! However, you cant use the type rating until you have passed an MCC?? It really begs the question as to how effectively this develops multi-crew skills.
