Kuros to SP pointers, I'd like to add that for a helicopter (of any size) those swiveling seats seem to be an awful lot of wasted space, more like a show off.
The specs in the web site do not really knock my socks off so to speak: the 189 already does 16 pax, 400nm plus and 150 Kts cruise.
Good luck in certifying the very first CIVILIAN FBW in a helicopter.
