Fuel type: piston vs turbine engines
The type of fuel a helicopter uses depends on the engine type. A piston helicopter engine uses "avgas", which is very similar to the regular gasoline used in cars. Piston engines are the same type of engine used in automobiles, where fuel is ignited in a combustion chamber, causing an explosion that moves the piston and rotates the rotor blades. Piston-powered helicopters are typically small and are used for sightseeing, flight training, and law enforcement. They are advantageous due to their low weight, high manoeuvrability, and low fuel consumption, ranging from 6 to 16 gallons of fuel per hour.
On the other hand, turbine helicopters run on jet fuel, similar to large airliners. Turbine engines are more powerful, lightweight, reliable, and efficient at high altitudes compared to piston engines. They are commonly used in medium-sized to large helicopters. However, they consume more fuel and are more expensive. Larger turbine-powered helicopters can use anywhere between 20 to several hundred gallons of fuel per hour.
In terms of performance, piston engines, such as the Lycoming, are reliable and durable. They have a complex system with numerous moving parts, which contributes to their smooth operation. Turbine engines, like the Pratt & Whitney's PT6A, stand out for their impressive reliability and longevity. With only about 10 moving parts, they operate smoothly and have a high power-to-weight ratio. Turbine engines also have faster climb rates and longer intervals between required overhauls, reducing maintenance frequency.
When it comes to fuel efficiency, piston engines have a slight edge. At optimum altitude, the Meridian, a turbine-powered aircraft, burns about 31 gallons per hour compared to 20 gallons per hour for the Mirage, a piston-powered aircraft. This difference is due to the lower specific fuel consumption of piston engines. However, jet fuel used in turbine engines is often less expensive and more readily available worldwide.
In summary, piston engines offer lower fuel consumption, lightweight construction, and high manoeuvrability, making them suitable for smaller helicopters. Turbine engines, on the other hand, provide increased power, reliability, and performance at high altitudes, but at the cost of higher fuel consumption and price. The choice between piston and turbine engines depends on the specific requirements and budget of the helicopter operator.

Fuel efficiency: gallons per hour
The fuel efficiency of a news chopper depends on several factors, including the type of engine, size, and operational mode. Here's a breakdown of the fuel efficiency of gallons per hour for different types of helicopters:
Piston-Powered Helicopters
Piston-powered helicopters, also known as piston engine helicopters, are typically smaller and less powerful than their turbine counterparts. They are commonly used for sightseeing, flight training, and law enforcement. These helicopters usually consume between 6 and 16 gallons of fuel per hour. For example, the Robinson R-22, a popular piston-powered helicopter, burns around 10 gallons of fuel per hour. Piston-powered helicopters are generally more fuel-efficient than turbine-powered helicopters and are suitable for occasional flights.
Turbine-Powered Helicopters
Turbine-powered helicopters, often equipped with jet engines, are larger and more powerful. They offer advantages such as increased reliability, lift capacity, and power. However, they consume significantly more fuel. While a small turbine-powered helicopter may use a minimum of 20 gallons of fuel per hour, larger ones can burn hundreds of gallons of fuel per hour. Military helicopters, for instance, are designed for speed, agility, and equipment-carrying capacity, resulting in higher fuel consumption.
Hovering vs Forward Flight
It is important to note that a helicopter's fuel efficiency also varies with its operational mode. When hovering, the helicopter's main rotor must generate all the lift, requiring more fuel. In contrast, during forward flight, the helicopter experiences increased airflow through the rotors, reducing the amount of fuel needed to create lift. Therefore, helicopters generally consume more fuel when hovering than when cruising.
Fuel Type
The type of fuel used also impacts fuel efficiency. Piston-powered helicopters typically use "avgas," which is similar to regular gasoline but without ethanol. Turbine-powered helicopters, on the other hand, use jet fuel, which is also used by large airliners. The choice of fuel depends on the engine type, with piston engines favouring "avgas" and turbine engines requiring jet fuel.

Fuel cost: price per gallon
The fuel cost per gallon for a news chopper depends on several factors, including the type of fuel, the size of the helicopter, and the price of fuel per gallon. Helicopters typically have two types of engines: piston and turbine. Piston-powered helicopters, also known as piston engines, are similar to the engines in cars. They are cheaper, lighter, and highly manoeuvrable, making them popular for news choppers. These helicopters use "avgas", which is similar to regular gasoline but without ethanol. On the other hand, turbine-powered helicopters, often medium to large choppers, use jet fuel, the same type used by large airliners. They are more powerful, reliable, and efficient at high altitudes but consume more fuel.
The fuel consumption of a news chopper varies based on its size and engine type. Small piston-powered helicopters typically use between 6 and 16 gallons of fuel per hour, while larger turbine-powered helicopters can consume 20 gallons or more per hour, with some using several hundred gallons. For example, the Robinson R-22, a popular piston-powered helicopter, burns around 10 gallons of fuel per hour, resulting in a fuel cost of $50 per hour if avgas is estimated at $5 per gallon.
The price of helicopter fuel can vary depending on the grade and location. In the United States, Jet A fuel is commonly used, while other countries may use Jet A-1 or other grades. The price per gallon can fluctuate, but for estimation purposes, avgas is often quoted at $6 per gallon, and jet fuel (Jet A) at $5 per gallon. These prices are generally consistent with other aircraft fuel prices.
It is worth noting that news choppers may also incur additional costs beyond fuel. Maintenance and repairs for helicopters can be expensive and specialised, with mandatory inspections and unexpected part replacements contributing to the overall cost of ownership. Other factors such as hangar fees, insurance, and navigation equipment expenses should also be considered when calculating the overall operating costs of a news chopper.

Maintenance and repairs: additional costs
The maintenance and repair costs of a news chopper are significant and can quickly add up. These costs are generally higher than those for car maintenance due to the specialised nature of helicopter maintenance and the lack of a competitive market. Major components such as engines and rotor systems require mandatory inspections at specific intervals, and unexpected issues and repairs can further increase expenses.
The type of helicopter also influences maintenance and repair costs. Turbine-powered helicopters, typically medium to large choppers with jet engines, are more powerful and reliable but tend to be more expensive to operate and maintain. Piston-powered helicopters, on the other hand, are cheaper to maintain and more fuel-efficient, making them a more economical choice for occasional flights. However, for news choppers that may need to operate in cold climates or transport multiple people, the benefits of turbine-powered helicopters may outweigh the higher maintenance costs.
The size of the helicopter is another factor affecting maintenance expenses. Larger helicopters may require more extensive repairs and parts replacements, increasing overall costs. Additionally, the availability of specialised mechanics and technicians for helicopter maintenance can impact costs, as limited options may result in higher prices for their services.
To manage maintenance and repair costs, news organisations may opt for comprehensive maintenance plans or in-house maintenance teams. Regular inspections and preventative maintenance can also help identify issues early on, reducing the need for costly repairs. While maintenance and repairs are significant expenses, they are necessary to ensure the safety and operational readiness of news choppers.
Overall, the maintenance and repair costs of a news chopper can be substantial and unpredictable, influenced by factors such as the type of helicopter, its size, and the availability of specialised maintenance services. Proper planning, preventative maintenance, and proactive issue identification can help mitigate some of these costs.

Fuel tank size: capacity and burn rate
The fuel tank size and burn rate of a news chopper depend on various factors, including the helicopter's model, size, weight, and engine type.
Piston-powered helicopters, which are typically smaller, have lower fuel consumption. They use "avgas," which is similar to regular gasoline, and their engines are comparable to those found in automobiles. These helicopters usually burn between 6 and 16 gallons of fuel per hour, with ultralight helicopters burning as little as 6 gallons per hour.
On the other hand, turbine-powered or jet-engine helicopters are more powerful and lighter relative to their output. They are commonly used for medium-sized to large helicopters and burn significantly more fuel. Military helicopters, for example, are often large and equipped with powerful engines, resulting in high fuel consumption. The MIL MI-26 helicopter, with its two 11,000 horsepower jet engines, burns 1000 gallons of fuel per hour.
It's worth noting that helicopters use more fuel when hovering than when in forward flight or cruise. During hovering, the main rotor must generate all the lift, requiring the acceleration of a large amount of air. However, in forward flight, the helicopter benefits from additional airflow, reducing the amount of acceleration needed to create lift.
The fuel burn rate also varies across different models. For example, a Cessna 150 burns around 5.5 gallons per hour, while a Robinson D-22 burns approximately 10 gallons per hour.
Additionally, the cost of fueling a news chopper can vary depending on the size and specifications of the aircraft. According to a news report from 2005, the Pakistani government incurred fuel costs ranging from Rs50,000 to Rs90,000 (approximately $600 to $1,000) per hour for helicopters engaged in earthquake relief operations.
