AW139 training.
We had a one week ground school and 2 weeks on the SIM in Whippany, 25 hours on the left seat and 25 hours on the right seat (Flying seat) before doing the check ride and it looks just enough to get use to all profile and system available on this machine.You are still looking for your "marks" the first week you fly the real machine and after it is OK.It looks complicated but in reality it is not so hard.It is important to know all systems and the QRH.
