If possible, do you know which schools offer such combination of IR and TR?
I think itīs not possible (I mean, there is no IFR certified AS350īs in Europe...or school with them...only 355 twin..better solution IMHO).
There is only a few of dinosauruses (long-rangers B206) and thatīs all regards the SE/IR(H).
Rather take multi-eng IR on 355.
