Multi-crew cooperation[1][2] (MCC) is a training course that allows aircraft pilots to fly multi-crew aircraft.
It is a requirement before a pilot may undertake a multi-crew aircraft type rating.
It is also required for the issuance of an airline transport pilot license (ATPL) or a multi-crew pilot license (MPL).
[2] In the European Union and the United Kingdom, MCC courses are regulated under Part-FCL 735.
This covers additional material including swept wing aircraft.
