How much does it cost to fuel a helicopter trip?
Assuming the helicopter is using standard 100LL (low lead) avgas the cost for a 200 mile trip will obviously depend on the cost of the gas and the MPG of the helicopter. See the first source for average prices in your area. It looks to be about $4.25/gallon. Picking a helicopter at random like the Sikorsky in the second source I think we can safely say a more typical helicopter gets 2 mpg. To go 200 miles you will need 100 gallons at 4.25 costing you $425.
