MRH90 Self Deployment Range
Useful payload - (MAUW - Basic W) around 2800 KG (with dispensations)
Max Internal Fuel - 2000Kg
Fuel Burn - 500Kg / hour
TAS still wind - around 140?
Range - around 490 nm with reserves.
Not much left for other payload.
However, show me another helicopter of this size and capability that can do better on INTERNAL FUEL? With external that will obviously add another 800KG (1.6 hours or 200ish nm).
