Jet A1 Fuel: What makes it best among aviation fuels

Aircrafts require refined fuel as compared to vehicles on the ground. Standard gasoline/petrol or diesel is not suitable for aero planes. Powerful piston engines and jet turbines require petroleum with high energy content and quality to perform efficiently. Like all other kinds of fuels, aviation fuels are also extracted from the same raw material called crude oil. Jet A, Jet A-1 and Jet B are three major kinds of fuels, which are used across the world in aviation industry. Among these three, Jet B is purposefully designed for freezing weather. It is used in aircrafts with civilian turbine-engines.

Though same automobile gasoline was used during early days of flight operation to power the aircrafts, it was unable to fulfill the growing requirements of the aviation sector. Soon after the development of piston-driven aero planes in the 1930s and 1940s, gasoline fails to remain the best choice. The low flashpoint of 30° Fahrenheit or 1° Celsius (temperature at which liquid petrol converts it into ignitable fumes) significantly increases fire risks. To overcome these issues petrochemical scientists extracted a new product after distillation of traditional precursor.

What is commercial jet fuel?

Chemically, commercial jet fuel is similar to kerosene. In fact, it’s purified kerosene with significantly higher flashpoints of 120° Fahrenheit (49° Celsius). Different freezing point is the only aspect of differentiation between Jet A (-40° C) and Jet A1 (-47° C) fuels. In addition to differences in freezing points, products from different manufacturers may differ from each other. Depending on the environmental conditions they may either have static dissipater additives.

What is chemical composition?

Aviation fuels are extracted from crude oils, Kerosene based compounds Jet A and Jet A-1 possess 8-16 carbon atoms per molecules, whereas Jet B is known as wide-cut or naphtha-type has 5-15 carbon atoms per molecule. Before purification, it may also contain a small percentage of other elements like Sulphur, nitrogen and metals. These metals are integrated within the hydrocarbons, which are removed after purification.

What makes Jet A-1 the best fuel choice?

Jet A1 fuel in Dubai is listed on the top among aviation fuel choices because of its desirable qualities. It appears colourless or slightly yellow. Higher flashpoints and tendency to remain stable at extremes of temperature both cold and hot make its perfect for air crafts. Great potential against heat enables it to deliver maximum energy at minimum weight. In addition to showing stability at higher temperatures, it also has an excellent level of cold resistance. It remains unaffected and maintains its liquid texture and viscosity at lower temperatures. It doesn’t crystallise at higher altitudes under freezing temperatures.

Instead of showing resistance to the extreme of temperatures, kerosene-based volatile liquids are listed among few highly stable petroleum products. They are not readily affected by oxidation processes. This high level of stability against degradations and environmental conditions have also made Jet A1 suitable to use as hydraulic fluid for engine control systems and cooling agent for a specific component in a fuel system.

Endnote: Jet A1 fuel in Dubai has become an ideal fuel option for the aviation industry. Unique chemical properties and good product stability are vital components making it extremely suitable for airplanes.
