There is no such thing as "ATPL(H) IR"……basically, you get an ATPL(H)…..then you can fly as PIC on Multi-Pilot Helicopter..
The IR is just an "add on"-so a MPH IR is similar to the "old" second part of the ATPL-checkride (which consisted of a VFR and an IFR part…)..
I will be doing some checks in the simulator in Stockholm soon…..if you are interested….not sure if it would be cheaper than doing it at your home place, though…(Flights to Stockholm and back are around 300 Euros there and back)..
Let me know if you should want to jump in….i have 2 candidates so far..
