A1 jet fuel, commonly referred to as Jet A1, is a standardized type of aviation fuel used primarily in commercial jet engines. It is a high-quality kerosene-based fuel designed to meet the rigorous specifications for aircraft operation. Jet A1 is characterized by its low freezing point (around -47°C or -53°F), which ensures reliable performance in a wide range of temperatures and altitudes. It is also formulated to provide optimal combustion efficiency and engine performance, with stringent controls on impurities and contaminants. This fuel is essential for ensuring safe and efficient flight operations in both domestic and international aviation.
