What You'll Learn
Fuel type: Jet A, Jet A-1, 100LL, or unleaded
The type of fuel used by a helicopter depends on the engine type. Turbine-engine helicopters use Jet-A or Jet-A1 kerosene-based fuel because of its high heat content and performance stability. Jet A-1 was priced at approximately $816 per metric tonne as of January 2022, which equates to about $0.82 / £0.61 per kg. This price is around double what it was a year prior.
Piston-engine helicopters, on the other hand, are relatively rare and require aviation gasoline or avgas, which is suitable for high-compression engines. Avgas costs around \$6 per gallon. One of the most popular helicopters in the world, the Robinson R22, uses avgas and has a 26-gallon fuel tank, costing $156 to fill.
Biofuels can be used in aircraft as a blend with conventional aviation fuels, and sustainable aviation fuel (SAF) is being produced to reduce the carbon footprint of air travel.
Unleaded fuel is not mentioned in the sources as a type of fuel used in helicopters.

Fuel prices: $6.29-$10.34 per gallon
The price of helicopter fuel depends on various factors, including the type of helicopter, the size of its fuel tank, and its fuel efficiency. The type of engine and fuel used also play a role in determining fuel costs. For example, piston-powered helicopters are generally cheaper to run and more fuel-efficient than turbine-powered helicopters, as they burn fuel at a lower rate.
The price of helicopter fuel can vary, with sources indicating prices ranging from $6.29 to $10.34 per gallon. The national average price for jet fuel is $6.29 per gallon, while the national average price for 100LL aircraft fuel is $6.50 per gallon. However, prices can be higher in certain regions, such as the FAA Alaska region, which reported an average jet fuel price of $8.11 and an average 100LL price of $10.34.
The type of helicopter also affects fuel costs. Smaller helicopters with relatively small engines, such as the R22, may have limited range and cargo capacity, but they can be more fuel-efficient. In contrast, larger helicopters with more powerful engines, such as the MIL MI-26, can burn up to 1,000 gallons of fuel per hour.
Additionally, the altitude at which a helicopter operates can impact fuel burn and costs. For instance, the Bell 206 JetRanger burns between 26 and 30 US gallons (98 to 114 liters) of fuel per hour, depending on the altitude and configuration. At an average fuel price of $6.97 per gallon, the fuel cost per hour for the JetRanger can range from $181.22 to $209.10.
It is worth noting that helicopter maintenance and operating costs can be significant, and these expenses should be considered alongside fuel prices when evaluating the overall cost of helicopter ownership or usage.

Fuel efficiency: Small piston engine helicopters are more efficient
The cost of helicopter fuel depends on the type of engine and fuel, as well as the size of the helicopter's fuel tank. Typically, the price of helicopter fuel is the same as that of any other aircraft fuel. However, the frequency of refuelling and the amount of fuel burnt influence the overall fuel cost.
Small piston engine helicopters are more fuel-efficient than their larger turbine-powered counterparts. Piston-powered helicopters burn fuel at a lower rate, typically consuming between 5-20 gallons/19-76 litres per hour, while larger turbine helicopters burn between 25-1100 gallons/95-4165 litres per hour. For example, the Robinson R22, one of the most popular and economical helicopters, has a 26-gallon fuel tank and would cost approximately $156 to fill, assuming a price of $6 per gallon for aviation gasoline (Avgas). In contrast, the Bell 206 JetRanger, a popular turbine-powered helicopter, has a 70-gallon tank and would cost about $350 to fill, with aviation turbine fuel (Avtur) priced at $5 per gallon.
Piston engine helicopters, such as the Robinson R44, are generally less expensive to operate and maintain than turbine engine helicopters. They are ideal for training, personal transportation, and sightseeing due to their smaller size and lower seating capacity. Additionally, piston engines provide more room for error as there is less concern about over-temping or accidentally pulling too much power, which can cause costly damage in turbine engines.
However, it is important to note that piston helicopters have shorter ranges and lower power margins when carrying passengers or cargo. Turbine engines offer superior performance, particularly in challenging environments characterised by high temperatures, humidity, and altitudes. They also provide increased reliability, lift capacity, and power, making them suitable for transporting larger groups of people and accommodating more luggage.

Fuel burn: 5-20 gallons/hour vs 25-1100 gallons/hour
The amount of fuel burnt by a helicopter depends on several factors, including the size of the helicopter, the type of engine, and the fuel used. Small piston engine helicopters are more fuel-efficient, burning fuel at a rate of 5-20 gallons/19-76 liters per hour. On the other hand, larger helicopters with turbine engines burn fuel at a much higher rate of 25-1100 gallons/95-4165 liters per hour. For example, the MIL MI-26, a Soviet/Russian transport helicopter, burns an astonishing 1000 gallons of fuel per hour.
The cost of fueling a helicopter depends on the price of fuel, which can vary. For instance, avgas may cost $6 per gallon, while aviation turbine fuel may cost $5 per gallon. Using these prices, fueling a popular and economical helicopter like the Robinson R22, with a 26-gallon fuel tank, would cost around $156. In contrast, the Bell 206 JetRanger, a popular turbine-powered helicopter with a 70-gallon tank, would cost approximately $350 to fuel.
It is important to note that the amount of fuel a helicopter can carry does not necessarily determine its range or endurance. Larger helicopters with bigger fuel tanks will also be heavier, requiring more fuel to generate the necessary power to move. Additionally, hovering and drag can significantly impact fuel consumption, as these maneuvers require more power and, consequently, burn more fuel.
To estimate the cost of owning and operating a helicopter, one must consider not only the fuel efficiency and fuel prices but also the frequency of flights and the type of helicopter. Maintenance and operating costs can be calculated by adding up annual expenses and dividing them by the planned flying hours. Additionally, insurance costs, hangar or tie-down fees, and loan payments are annual fixed costs that must be factored in.
By considering all these factors, potential helicopter owners can make informed decisions about the ongoing costs and affordability of owning and operating a helicopter.

Fuel costs: $14,000-$21,000 per hour
The cost of operating a helicopter includes fuel and maintenance, which can range from $300 to $2000 per hour. The price of helicopter fuel depends on the type of aircraft and the altitudes flown. For instance, the Bell 206 JetRanger consumes between 26 and 30 US gallons (98 to 114 litres) of fuel per hour, with an estimated fuel cost of $181.22 to $209.10 per hour, based on a JetA fuel price of $6.97.
The R22 helicopter, with a cost of $350 per hour, can incur fuel expenses of $14,000 to $21,000 for flight hours alone. This excludes other costs such as ground instruction and checkride fees. The fuel efficiency of helicopters is influenced by their design, engine type, and fuel used. Piston-powered helicopters, for example, have better fuel economy than gas turbine-powered helicopters due to their lower fuel burn rate.
The type of fuel utilised also impacts fuel costs. Turbine-powered helicopters typically operate on jet fuel, while piston-powered helicopters in North America and Western Europe often use aviation gasoline grade 100LL, which contains tetraethyl lead to prevent detonations during combustion. Additionally, the size of the helicopter affects fuel efficiency, with larger helicopters capable of carrying more fuel but varying in efficiency depending on their engine and design.
To optimise fuel costs, helicopter owners can consider factors such as the type of aircraft, its fuel efficiency, and the availability of fuel at different locations. By researching and comparing fuel prices, as well as considering the altitudes and regions of operation, owners can make informed decisions to minimise fuel expenses. Additionally, choosing between piston and turbine helicopters based on usage needs can help balance fuel efficiency and transportation requirements.
