Helicopters are known to be expensive to own and operate, and fuel is a significant cost. The amount of fuel a helicopter uses depends on various factors, including the size of the helicopter, the type of engine and fuel, and the altitude and conditions in which it is flying. For example, a Bell 206 JetRanger helicopter burns between 26 and 30 US gallons (98 to 114 litres) of JetA fuel per hour, while a Bell 212 burns around 100 gallons of jet fuel per hour. Fuel prices also vary, just like automobile fuel prices, and can be a large expense for larger helicopters, especially those with multiple engines.

Fuel burn depends on helicopter make and model
The amount of fuel burnt by a helicopter depends on various factors, including its make and model, size, weight, type, and engine type. The type of fuel used by a helicopter depends on the type of engine it is equipped with. Helicopters with piston engines use AvGas, also known as 100LL, a high-octane, leaded fuel similar to gasoline. Helicopters with turbine engines use JetA, similar to jet fuel.
Helicopters with piston engines are generally smaller and have lower fuel consumption. For example, a Robinson D-22 burns around 10 gallons of fuel and can take you 110 miles. Small piston-powered helicopters typically use between 6 and 16 gallons of fuel per hour. Most piston-powered helicopters flying today are quite small and are used for sightseeing, flight training, and law enforcement.
On the other hand, helicopters with turbine engines, such as the JetRanger, burn more fuel. The Bell 206 JetRanger, for instance, burns between 26 and 30 US gallons (98 to 114 liters) of JetA fuel per hour. Larger turbine-powered helicopters can use a minimum of 20 gallons of fuel per hour, with some consuming hundreds of gallons per hour. The Bell 212 burns around 100 gallons of jet fuel per hour, while the twin-engine CH-47 Chinook burns between 350 and 400 gallons per hour in flight.
Military helicopters, which tend to be larger and have powerful engines, also burn a significant amount of fuel. They use more fuel when hovering than in forward flight as the main rotor has to create all the lift to keep the helicopter in the air. The type of mission and altitude can also impact fuel consumption.

Fuel costs are a fraction of overall operating costs
The cost of fuelling a helicopter depends on various factors, including the type of helicopter, the size of the helicopter, the type of engine, the fuel type, and the altitude at which it is flown. Helicopter engines can be piston-powered or turbine-powered, and the type of engine affects fuel efficiency. Piston-powered helicopters burn AvGas (also known as 100LL), a high-octane, leaded fuel similar to car fuel. Turbine-powered helicopters, on the other hand, burn JetA, which is similar to jet fuel. The Bell 206 JetRanger, for example, burns between 26 and 30 US gallons (98 to 114 litres) of JetA fuel per hour, resulting in a fuel cost per hour of $181.22 to $209.10 if the average JetA fuel price is $6.97.
While fuel costs are a significant expense, they are just a small fraction of the overall operating costs of a helicopter. Maintenance and overhaul costs, for instance, can be extremely high and difficult to estimate. Insurance is another major cost, with most helicopter owners purchasing liability insurance, which covers people and property affected by any accidents, and hull insurance, which covers the aircraft itself. Insurance costs are based on factors such as the aircraft's value, how often it is flown, and the experience level of the pilot. Additionally, unless the owner plans to keep the helicopter on their property, hangar or tie-down fees will apply, and these can vary depending on the airport.
Other costs to consider when owning a helicopter include the initial purchase cost, landing fees, pilot salaries, and the cost of fuel for transportation to and from the helicopter. These costs can add up quickly, and it is important for potential helicopter owners to carefully consider their budget and find ways to reduce expenses where possible, such as by choosing a different hangar or landing at less expensive airports.
While fuel efficiency varies based on the size and type of helicopter, as well as the conditions under which it is flown, it is worth noting that helicopters are generally less fuel-efficient than airplanes due to their method of generating thrust. Helicopters generate thrust from their rotors, requiring the engines to burn fuel in the process, especially during hovering. Therefore, when considering the overall operating costs of a helicopter, fuel costs, despite being a significant expense, are indeed just a fraction of the total expenses involved in owning and operating these aircraft.

Piston vs turbine engines use different fuel types
The cost of fuelling a helicopter depends on various factors, including the make and model of the helicopter, the conditions under which it is flown, and the type of engine it has. Helicopters generally use one of two types of fuel: AvGas or JetA.
Helicopters with piston engines, which are typically smaller helicopters, burn AvGas, a high-octane, leaded fuel similar to that used in cars. In contrast, helicopters with turbine engines burn JetA, the same type of fuel used in jet airplanes, which is also similar to diesel. The cost of these fuels varies, with JetA typically being more expensive than AvGas.
Piston engines in helicopters have a reciprocating engine, with power transmitted from either a four- or six-cylinder engine, similar to most land vehicles. They are typically less expensive to purchase and operate than turbine engines, but may not offer the same performance, range, or fuel efficiency. Piston engines are also generally easier to maintain due to serialized components that follow a set time schedule. Additionally, piston engines allow more room for error as operators don't need to worry about over-temping or accidentally pulling too much power, which can cause significant damage in turbine engines.
Turbine engines, on the other hand, have a gas turbine engine where compressed air is ignited, turning a series of turbine wheels. They offer superior performance due to higher power output and better coping with heavy loads, hot temperatures, humid conditions, and high altitudes. Turbine engines are also lighter in weight for the same horsepower, resulting in a better power-to-weight ratio. However, they are generally more expensive to maintain and own due to the increased cost of turbine engine components.
Overall, the choice between a piston and a turbine engine depends on specific needs, budget, and the willingness to take on the responsibilities of ownership. While piston engines may be more cost-effective, turbine engines offer improved performance and efficiency but come with higher maintenance and ownership costs. Owning a helicopter is generally a costly endeavour, and careful consideration should be given to the various expenses involved.

Fuel burn depends on altitude and conditions
Fuel burn depends on a variety of factors, including the make and model of the helicopter, the altitude, and the conditions in which it is being flown. For example, a helicopter flying near sea level in cool temperatures with a light load will burn less fuel than the same helicopter operating at maximum gross weight in hot temperatures.
The Bell 206 JetRanger, for instance, burns between 26 and 30 US gallons (98 to 114 liters) of JetA fuel per hour, depending on the configuration. The cost of fuel can also vary, with prices for JetA fuel differing from AvGas, which is used in helicopters with piston engines.
Altitude also plays a significant role in fuel consumption, with helicopters burning more fuel as they fly at higher altitudes. This is due to the increased power required to maintain lift and forward flight at higher altitudes, where the air density is lower. Therefore, when planning a flight, it is essential to consider not only the distance but also the altitudes at which the helicopter will be flying to accurately estimate fuel requirements.
Additionally, helicopters may burn fuel while on the ground, even when not in flight. This can occur during the warm-up phase, when the engines are running but the helicopter is not yet airborne. In some cases, helicopters may need to hot-refuel, or refuel with the engines running, which can impact the refueling time and overall efficiency.
Overall, understanding the factors that affect fuel burn, such as altitude and conditions, is crucial for effective flight planning and ensuring the safe and efficient operation of helicopters. By taking these factors into account, pilots and operators can make informed decisions regarding fuel loading, range, and endurance for their specific aircraft and mission profiles.

Maintenance and insurance are additional costs
Kenny Morrow, the chief operating officer for Metro Aviation, has developed a system to predict operating costs based on two parts: the average hourly labour cost and the specific aircraft's age and intended use. Morrow recommends purchasing aircraft cost reports that break down all operating and maintenance costs based on the aircraft's make and model. These reports provide an average per-hour maintenance cost and overall operating cost.
Insurance is another indispensable aspect of helicopter operations. The cost of insurance varies widely depending on the type of helicopter, the frequency of use, and the amount of coverage required. There are two main types of insurance most helicopter owners purchase: liability and hull. Liability covers the people onboard, as well as the people and property on the ground affected by an accident or incident. Hull covers the aircraft itself. The insurance broker will help determine the best rates based on the aircraft's value, flight frequency and experience, and intended use.
