Jet A-1 Fuel Overview
Jet A-1 is a kerosene-based aviation fuel used in commercial and military aircraft with turbine engines (jet engines and turboprops). It meets international aviation fuel standards and is widely used worldwide, except in the U.S., where Jet A is more common.
Key Features of Jet A-1 Fuel:
- Flash Point: ≥ 38°C (100°F) (Safe for handling and transport)
- Freezing Point: ≤ -47°C (Better cold-weather performance than Jet A)
- Density: 0.775 – 0.840 kg/L at 15°C
- Energy Content: 42.8 MJ/kg (High efficiency for long flights)
- Sulfur Content: Max 0.3% (Low sulfur emissions)
- Additives: Contains antistatic agents, corrosion inhibitors, and antioxidants to enhance performance and safety.
