The comparison site I was using defined capacity as "the number of people that can comfortably be seated in the helicopter, including the pilot."
I thought this was a bit misleading, as normally I would exclude pilot from "pax" but I went along with it. I have a family of four, 2 adults and two children…and baggage, to move. As as far as range in concerned, 120 miles does it, so everything seems to manage that(!)
The same site comparison had 520 with 48 cu ft baggage and 204 nm range.
I added the AS350 and see that it is no more expensive to buy, is larger and faster, but (according to them) uses more fuel.
Still a good addition to the list. Thanks guys!
