Mmmmm ...
....
what are the other points of difference in the HEMs role in the Victorian environment between it and the 139? ....
Well I would suggest "capability" would be the biggest ... the B412 is really at the end of its development even though Bell would like not to admit it ...
The 139 has a payload & speed advantage and more potential into the future. It is also a bit more capable (but far from perfect) in the single pilot role with respect to SAR, Rescue & IFR ops.
Yes it
may well be more expensive to operate ... but the reliability and capability might outweigh that disadvantage.
