Aviation Fuel
Aviation fuel is a specialized type of fuel used to power aircraft. These fuels are either derived from petroleum or are blends of petroleum and synthetic fuels. The primary types of aviation fuel include Jet Fuel, Aviation Gasoline (Avgas), and Aviation Biofuel.
Jet Fuel
Jet fuel, also known as Aviation Turbine Fuel (ATF), is a type of aviation fuel designed specifically for use in aircraft powered by gas-turbine engines. It is the most common type of aviation fuel and is used by commercial airlines and the military. Jet fuel is typically clear to straw-colored and is produced to a standardized international specification.
Types of Jet Fuel
- Jet A and Jet A-1: These are kerosene-based fuels used widely in the United States and around the world, respectively.
- Jet B: This is a fuel in the naptha-kerosene region that is used for its enhanced cold-weather performance. It is primarily used in some Canada and Alaska operations.
Aviation Gasoline (Avgas)
Avgas is specially formulated for aircraft with spark-ignited internal combustion engines. It is similar to automotive gasoline but with additives to enhance performance and stability at high altitudes. Avgas is dyed to distinguish it from other fuels. The most common type is 100LL (Low Lead), which is suitable for most piston-engine aircraft.
Aviation Biofuel
Aviation biofuel, also known as sustainable aviation fuel (SAF), is a biofuel used to power aircraft and is seen as a key component in reducing the aviation industry's carbon footprint. These fuels are produced from renewable resources such as algae, jatropha, and other plant materials.
Environmental Impact
The aviation industry has been working to reduce the environmental impact of traditional aviation fuels. The use of aviation biofuels and the improvement of fuel economy in aircraft contribute to efforts to decrease greenhouse gas emissions. However, overall emissions have risen as the volume of air travel has increased.
Taxation and Regulation
In the European Union, taxation of aviation fuel is regulated by the Energy Taxation Directive. This prohibits the taxation of commercial aviation fuel, though there have been discussions about potential changes to support climate action.
Fuel Economy in Aircraft
Efforts to improve fuel economy in aircraft involve innovations in aircraft design, aerodynamics, and engine efficiency. These improvements are crucial as they relate to climate action and the rising costs of sustainable aviation fuels compared to traditional kerosene.
