Jet fuel, also known as aviation fuel, is a type of fuel designed for use in aircraft powered by gas-turbine engines. It is a refined petroleum product that is similar to kerosene. Jet fuel is characterized by its low freezing point, high flash point, and high energy density, which are crucial for safe and efficient operation at high altitudes and varying temperatures.

There are two primary types of jet fuel: Jet A and Jet A-1. Jet A is primarily used in the United States, while Jet A-1 is the standard globally. The main difference lies in their freezing points, with Jet A-1 having a lower freezing point to better accommodate colder operating conditions. Both types are required to meet stringent safety and performance specifications set by international aviation authorities.

The production of jet fuel involves fractional distillation of crude oil, separating hydrocarbons based on their boiling points. Additives are often included to enhance properties like thermal stability, anti-static, and anti-icing capabilities. The energy content of jet fuel is a critical factor in determining an aircraft's range and payload.

Due to its specialized nature and critical role in aviation safety, jet fuel undergoes rigorous quality control and testing throughout its production, transportation, and delivery process. Any contamination or deviation from specifications can have severe consequences. The sustainability of jet fuel is an increasing area of research, with efforts focused on developing and implementing sustainable aviation fuels (SAFs) derived from non-petroleum sources.
