The AW139 burns 880 pph.
What do you mean "the S92 is full Cat A". At what OAT and how much wind??
The AW139, as I said previously, is full Cat A at max weight and ISA+25 at zero wind.
Based on complete figure and at the same conditions, you can then compare range.
Can S92 have 300 nm range at ISA+25 and be full Cat A? How many passengers on board?
