What You'll Learn
Fuel prices vary
The cost of helicopter fuel also depends on the size of the helicopter and its fuel efficiency. Larger helicopters have bigger fuel tanks and burn more fuel, especially during takeoff and when carrying heavy loads. Additionally, the number of engines in a helicopter affects fuel consumption, with more engines resulting in higher fuel usage.
The price of aviation fuel, including AvGas and Jet Fuel, fluctuates and varies by location. For example, in 2020, AvGas prices ranged from $4.60 to $5.34 per gallon, while Jet Fuel prices ranged from $3.90 to $4.54 per gallon in the lower 48 states. In remote locations, such as the Northern Arctic regions, fuel prices can be significantly higher, with AvGas costing up to $50 per gallon.
The fuel burn rate of helicopters also varies based on their make and model, similar to how a larger car engine burns more fuel than a compact car. Helicopters with higher fuel burn rates will consume more fuel per kilometer. Additionally, fuel burn rates can be affected by conditions, just like in automobiles.

Fuel tank size matters
Larger helicopters have bigger fuel tanks and can carry more fuel, but this also increases their weight, requiring more fuel to generate the necessary power to move. Therefore, bigger helicopters might not necessarily fly longer distances or consume fuel more efficiently despite having larger fuel tanks.
The type of engine and fuel also play a significant role in fuel efficiency. Piston-powered helicopters, for instance, are more fuel-efficient than gas turbine-powered helicopters as they burn fuel at a lower rate. Additionally, the design of a helicopter affects fuel efficiency. Unlike airplanes, helicopters generate thrust from their rotors, requiring the engines to burn fuel in the process, especially during hovering.
The number of fuel tanks can also impact fuel efficiency. Helicopters with multiple tanks can manage fuel better, preventing issues like fuel starvation in multi-engine helicopters. Furthermore, altitude is a factor in a helicopter's range, with higher altitudes requiring more fuel.
In summary, while fuel tank size does matter, it is just one of several factors influencing the cost of helicopter fuel per kilometre. The type of helicopter, engine, fuel, design, number of fuel tanks, and operating altitude all contribute to fuel efficiency and the overall fuel cost per kilometre.

Engine type impacts cost
The type of engine a helicopter is equipped with determines the type of fuel it uses. Turbine-powered helicopters, usually medium to large helicopters, are equipped with jet engines and use jet fuel. Jet fuel A is the most popular grade used in the United States, with other grades like jet fuel A-1 being more common in other countries. Jet fuel is cheaper than aviation gasoline (avgas), which is used in piston-powered helicopters. Avgas is the only aviation fuel that contains lead.
Turbine-powered helicopters are more powerful than piston-powered helicopters, but they are more expensive to operate and maintain. Turbine-powered helicopters can carry anywhere from 4 to 12 people and provide more luggage space, more comfortable seating, and slightly less noise. On the other hand, piston-powered helicopters are usually much smaller and can only seat a couple of people, making them a common choice for training, personal transportation, and sightseeing. The police also use piston-powered helicopters for general surveillance due to their high maneuverability.
While piston-powered helicopters are cheaper to maintain and more fuel-efficient, turbine-powered helicopters provide more reliability, lift, and power. If you are looking to transport more than 3 people or operate in cold climates, it is more economical to opt for a turbine-powered helicopter.
The cost of fueling a helicopter depends on the size of the helicopter's gas tank, the type of gas it uses, and the price of the fuel. For example, the Bell 206 JetRanger, a popular turbine-powered helicopter, costs $350 to fill its 70-gallon fuel tank. In contrast, the Robinson R22, one of the most economical helicopters, costs $156 to fill its 26-gallon fuel tank.
The amount of fuel a helicopter consumes also varies depending on its size, weight, and engine type. Helicopters use more fuel when hovering than in mid-flight as the main rotor has to create all the lift to keep the helicopter in the air. A small piston-powered helicopter typically uses between 6 and 16 gallons of fuel per hour, while a large turbine-powered helicopter can use anywhere from 20 to several hundred gallons of fuel per hour.

Remote locations cost more
The cost of helicopter fuel per kilometre depends on several factors, including the type and size of the helicopter, the type of engine and fuel, and the frequency of refuelling. The price of fuel also varies across locations, with remote areas incurring higher costs.
Remote locations often have fewer infrastructure facilities, and airports or heliports may not be readily available. In such cases, helicopters need to be refuelled using fuel bowsers or drums, which are placed in the field ahead of time by a contractor or flown out using a longline and net. This additional transportation cost adds to the overall fuel expense.
The process of refuelling from drums is also more time-consuming and less efficient than using a fuel truck or pump station at an airport. Each 55-gallon drum contains around 250 litres, and fuelling multiple drums can take 20-40 minutes from landing to takeoff. The slower process may impact the overall cost, especially for urgent or time-sensitive operations.
Furthermore, remote areas may experience fluctuations in fuel availability, leading to potential shortages and higher prices. The challenge of accessing fuel in remote locations can significantly influence the overall cost of helicopter operations in these regions.
The cost implications of refuelling in remote locations are significant, and operators must carefully consider the logistics and expenses involved in ensuring a steady fuel supply. The additional costs associated with remote refuelling contribute to the overall expense of helicopter fuel per kilometre in these areas.

Fuel burn rate calculations
The fuel burn rate of a helicopter is dependent on several factors, including the type of helicopter, the size of the engine, the weight of the aircraft, and the conditions in which it is flying.
The type of helicopter and its engine play a significant role in fuel burn rate calculations. For instance, turbine engine-powered helicopters tend to have larger fuel tanks and burn more fuel compared to piston-powered helicopters. Piston-powered helicopters are more fuel-efficient for occasional flights and smaller groups of up to three people. However, for transporting more passengers or operating in colder climates, turbine helicopters are more economical.
The size of the engine also contributes to the fuel burn rate. Generally, bigger engines will burn more fuel, similar to how an SUV consumes more fuel than a compact car. Additionally, the weight of the helicopter affects fuel efficiency. Larger helicopters or those with increased comfort features carry more weight, requiring more fuel to generate the necessary power to move.
Fuel burn rates can also vary depending on the conditions in which the helicopter is operating. Factors such as cruising speed, altitude, and external factors like wind or temperature can influence the amount of fuel burned during a flight.
To calculate the fuel burn rate, one can use the formula:
> Fuel Burn Rate = Total Fuel Burned / Flight Time
For example, if a helicopter burns 13.5 gallons of fuel in 1 hour and 27 minutes (1.45 hours), the fuel burn rate is calculated as:
> Fuel Burn Rate = 13.5 gallons / 1.45 hours = 9.3 gallons per hour
This calculation provides insight into the helicopter's fuel efficiency and can be used to estimate the cost of fuel per kilometer.

Frequently asked questions
The cost of helicopter fuel per kilometre depends on several factors, including the type of helicopter, its fuel efficiency, the price of fuel, and the distance travelled. Therefore, it is challenging to provide a precise answer. However, sources indicate that the price of aviation fuel typically ranges from $4 to $11 per gallon for 100LL AvGas and $4 to $6 per gallon for Jet A or Jet A-1 fuel.
The fuel efficiency of a helicopter is influenced by its size, engine type, and design. Larger helicopters tend to have higher fuel capacity but may also burn more fuel due to increased weight. Helicopters with more engines generally consume more fuel. Additionally, the type of engine, such as piston or turbine, can impact fuel efficiency, with piston engines being more fuel-efficient for occasional flights and smaller passenger counts.
The price of helicopter fuel can vary significantly across different locations. Fuel prices tend to be higher in remote areas, with costs reaching up to $30 per gallon for Jet A fuel and $50 per gallon for 100LL AvGas in certain regions. The accessibility of the fuel cache also impacts the price, with more remote sources incurring additional transportation costs.
The fuel efficiency of a helicopter can be compared to that of a car by considering the "straight-line" factor. While a helicopter can fly in a straight line, roads often involve less direct routes. Therefore, each air mile is estimated to be equivalent to 1.5 road miles. For example, a helicopter with a fuel burn rate of 14-16 gallons per hour can achieve 7.19 miles per gallon, which translates to 10.79 miles per gallon when adjusted for the "straight-line" factor. This is comparable to the fuel efficiency of some trucks and SUVs.
