What You'll Learn
The Boeing 767-300ER can carry 24,140 gallons of fuel
The Boeing 767-300ER is a wide-body airliner that can carry 24,140 gallons of fuel. This fuel capacity is divided into two wing tanks, which hold 6,070 gallons each, and a center tank, which holds 12,000 gallons. The 767-300ER has a range of over 6,600 nautical miles when fully fueled, although more typical ranges with lower fuel loads are 3,000 to 4,000 nautical miles for transcontinental flights.
The 767-300ER's impressive range capability is due in part to its fuel economy and capacity. This flexibility has made the 767 a popular choice for overseas routes and intercontinental services. The aircraft's fuel economy is also influenced by its engines, with the 767 typically being equipped with Pratt & Whitney or General Electric engines. These engines power the aircraft using standard aviation jet fuel, similar to kerosene and referred to as Jet A or Jet A-1.
Jet A and Jet A-1 fuels are colorless, easily combustible, and have a higher flash point than gasoline, making them suitable for large planes. Jet A-1 has a lower freezing point, making it preferable for colder climates. Jet B, on the other hand, is a higher volatility fuel used in colder environments.
The fuel consumption of the 767-300ER can vary depending on various factors, including the length of the flight, the number of passengers and cargo, and the efficiency of the engines. On long-haul flights, the aircraft may burn around 50,000 kg of fuel, while shorter flights will naturally require less fuel.

Jet A and Jet A-1 are common jet fuels used
The Boeing 767 is a popular aircraft for commercial aviation that has been adopted by airlines worldwide since its introduction in 1981. The 767-300ER variant of the aircraft can carry up to 24,140 gallons of fuel, enabling it to achieve a range of over 6,600 nautical miles. The standard aviation jet fuel used in the Boeing 767 is similar to kerosene and is known as Jet A or Jet A-1.
Jet A and Jet A-1 are the most commonly used jet fuels in commercial aviation. They are produced according to standardized international specifications and are well-suited for most aviation applications. These fuels are composed of hydrocarbons distilled from petroleum crude oil and possess properties that make them suitable for powering turbine engines at high temperatures and pressures during jet flight. Jet A and Jet A-1 have a minimum flash point of 38°C (100°F), ensuring safety during refueling and storage. A higher flash point means that the fuel is less likely to ignite accidentally, making it safer to handle and store.
The primary difference between Jet A and Jet A-1 is their freezing point. Jet A fuel starts to solidify around -40°C (-40°F), while Jet A-1 has a lower freezing point of -47°C (-52.6°F). This makes Jet A-1 better suited for colder climates, as it remains resistant to solidification at lower temperatures. Jet A is typically used in regions with milder or moderate climates, such as the USA, while Jet A-1 is favoured in colder regions and for international flights that encounter varying temperature conditions.
Jet A-1 fuel also includes an antistatic additive, which helps dissipate static electricity buildup and prevents sparking and ignition of vapours. Additionally, both Jet A and Jet A-1 fuels may contain other additives such as antioxidants to prevent gumming and icing inhibitors to prevent aircraft icing. These additives are crucial for maintaining the performance and reliability of jet engines in diverse climates and ensuring the safety of aviation operations.

Jet fuel is similar to kerosene
The Boeing 767 is a popular aircraft for commercial aviation that has been adopted by airlines worldwide since its introduction in 1981. The 767-300ER variant of the aircraft can carry up to 24,140 gallons of fuel and achieve a range of over 6,600 nautical miles. The Boeing 767 is equipped with high-bypass turbofan engines that are powered by standard aviation jet fuel, which is similar to kerosene. This type of fuel is sometimes referred to as Jet A or Jet A-1 and is a highly refined and purified liquid that is straw-colored or clear.
Jet fuel is produced from a blend of hydrocarbons distilled from petroleum crude oil and contains additives that improve its performance and safety. For instance, special additives are blended into jet fuel to serve as freezing point depressants and prevent ice crystal formation, which could affect fuel flow at high altitudes. Anti-static additives also help dissipate static electricity buildup, which could otherwise spark and ignite the vapors.
Jet fuel has a higher flash point and freezing point compared to other petroleum products, providing a measure of safety during storage and transportation. Additionally, jet fuel has a higher energy density than gasoline, which makes it suitable for powering turbine engines at the high temperatures and pressures required during jet flight.
Kerosene, which is sometimes called "fuel oil", is a less volatile fuel that burns slowly and relatively coolly. This makes it ideal for jet engines because it avoids pre-ignition problems and some safety hazards associated with higher-octane fuels. All jet fuels intended for aircraft use are based on kerosene, although some military jet fuels contain more volatile components.

Jet fuel is produced from hydrocarbons distilled from crude oil
The Boeing 767-300 has a fuel capacity of 20,112 imperial gallons (91,380 litres or 73,078 kg). The fuel consumption of this aircraft is 1,199 imperial gallons (5,451 litres or 4,360 kg) per hour for short-haul flights and 1,279 imperial gallons (5,813 litres or 4,650 kg) per hour for long-haul or regional flights.
The specific type of jet fuel used depends on the region and aircraft manufacturer. For example, civilian aircraft in the West primarily use Jet A or Jet A-1 fuel, while military aircraft use JP-5 or JP-8 fuel. Jet fuels in the former Soviet Union and Eastern Europe vary in grades, reflecting different crude sources and processing treatments. For instance, Chinese jet fuels are categorized into five types, previously labelled with the prefix "RP" and now named No 1 Jet Fuel, No 2 Jet Fuel, and so on.
In recent years, the aviation industry has been transitioning from crude oil-based fuels to Sustainable Aviation Fuel (SAF). Biofuels, produced from vegetable oils and plant materials, are one of the most promising advancements in this area. These alternative fuels offer lower emissions and reduced exhaust toxicity, closely resembling the properties of conventional jet fuel.

Jet fuel has a higher flash point than gasoline
The Boeing 767 is a popular aircraft for commercial aviation that has been adopted by airlines worldwide. The 767 is equipped with powerful engines that burn standard aviation jet fuel, which is similar to kerosene. This type of fuel is known as Jet A or Jet A-1 and is a highly refined and purified liquid with a straw-coloured hue.
Jet fuel has a higher flash point compared to gasoline, which is an important distinction in fuel characteristics. The flash point refers to the lowest temperature at which a liquid can vaporise and form an ignitable mixture with air. In other words, it is the temperature at which a fuel can ignite and burn. Gasoline, also known as petrol, has a flashpoint of -43°C, which means it can be easily ignited by sparks or static electricity.
On the other hand, jet fuel has a flashpoint of 38°C, which is significantly higher. This higher flash point provides several advantages for the use and safety of jet fuel. Firstly, it makes jet fuel relatively safer to transport and handle compared to gasoline. Secondly, the higher flash point allows jet fuel to withstand the extreme temperatures and pressures required during jet flight without igniting prematurely.
The Boeing 767, with its impressive range capability, benefits from the energy density and reliability provided by jet fuel. The 767-300ER variant, for example, can carry up to 24,140 gallons of fuel, enabling it to achieve a range of over 6,600 nautical miles. This fuel capacity, combined with the efficient turbofan engines of the 767, results in excellent fuel economy, making the aircraft a popular choice for long-haul and intercontinental flights.
