yes, that's exactly what we are seeking. A legal (of course...) way to write the copilot hours so that they will be countable for a future ATPl(H). That means, those hours have to be multi-pilot hours according EASA.FCL.
During my research, i got two main answers:
- To operate a ME-Helicopter below 3175kg/9seats with a multi-pilot crew all you need is a CPL(H), a MCC course and an AOC where the multi-pilot operation is described.
- Same as before, but both pilots need a frozen ATPL(H).
However, in EASA.FCL, there is no clear reading about this...
