Mmm..
I'm sorry Sans but there's a few mistakes there on the C++.
The average fuel fow is 700lbs/hr, even an A+ is 640lbs/hr.
155kts is the VNE of an S76 from A-C++. VNO is 10knts below VNE depending on Density Altitude.
Long range cruise speed is still VNO, 145kts-ish, you set 80% and normally get 145kts unless you're max all up weight.
Range is actually about 350-380, sticking 1900lbs in the tank is akin to getting John Goodman in to a shopping trolley after a night out.
Hope these corrections help to put the S76D in perspective. Sans, I'm aware you were directly quoting from Flight International so please don't take it as me being a pedantic git, just trying to inform..
