I hear you HC, point taken about Sim vs A/C
Well according to ETS website an Initial EC225 type rating consists of 18.5 hours in the Sim (IFR extension included), followed by 3 hours in the a/c & 1.5 hours checkride (In Sim presumably?)
The breakdown for American Eurocopter must be similar to ETS though it is not clear where the Sim portion is conducted (Presumably in either ABZ or MRS)
Since ERA has no EC225 Sim I would guess the 15 hours are a/c time?
