1. What It Is:
Jet Fuel A-1 is the most widely used aviation turbine fuel worldwide for commercial and military aircraft. It’s a kerosene-type fuel meeting strict international standards to ensure safe, efficient engine operation under varied conditions.
2. Key Specifications (Typical):
- Type: Kerosene-based aviation turbine fuel
- Flash Point: Min 38°C
- Freezing Point: Max −47°C (suitable for high altitude and cold weather)
- Density @15°C: ~0.775–0.840 kg/l
- Sulfur Content: Max 0.3% (some suppliers offer ULSD versions with <10 ppm sulfur)
- Viscosity @ −20°C: Max 8.0 mm²/s
- Energy Content: Approx. 42.8 MJ/kg
- Smoke Point: Min 25 mm (indicates combustion quality)
- Additives: Typically includes antioxidants, static dissipators, corrosion inhibitors
3. Applications:
- Commercial jet aircraft (airliners, cargo jets)
- Military jet aircraft and helicopters
- Turbine-powered small aircraft
- Some industrial gas turbines
4. Environmental & Safety:
- Designed for clean burning to reduce engine deposits and emissions
- Stable over a wide temperature range for safe storage and flight at altitude
- Meets ASTM D1655 or DEF STAN 91-91 specifications globally
5. Market & Trade:
- Produced by most major oil refiners worldwide
- Delivered by pipeline, tanker, or barge to airports
- Subject to rigorous quality control (Q&Q) and inspection (e.g., SGS, Saybolt)
6. Comparison:
- Jet A-1 has a lower freezing point than Jet A (−47°C vs. −40°C), making it suitable for international flights and colder climates.
