3.     Freezing Point: Jet A1 fuel has a maximum freezing point of -47°C (-53°F), making it suitable for cold weather and high-altitude flights.

4.     Density: The density of Jet A1 fuel ranges from 0.775 to 0.840 kg/L at 15°C (59°F), ensuring consistency in fuel weight calculations.

5.     Energy Content: The energy content of Jet A1 fuel is approximately 43.15 MJ/kg, making it a high-energy fuel for aviation purposes.

These specifications are essential for maintaining safety, performance, and efficiency in aviation, ensuring compatibility with aircraft engines and fuel systems.

Jet A1 Fuel Weight

Jet A1 fuel weight is a critical factor in aircraft performance, affecting takeoff weight, fuel efficiency, and overall flight safety. The weight of Jet A1 fuel is influenced by its density, temperature, and storage conditions.

Jet A1 fuel has a density range of 0.775 to 0.840 kg/L at 15°C. This density variation results in different weights depending on temperature and location. The higher the density, the heavier the fuel per unit volume.

For flight planning, airlines and pilots use standard fuel weights to calculate fuel load. The weight of Jet A1 fuel directly impacts aircraft range and fuel economy. Lighter fuels increase efficiency, while heavier fuels may require adjustments in flight plans to optimize performance.

Jet A1 Fuel Weight Per Litre

Jet A1 fuel weight per litre varies based on density and temperature. At a standard temperature of 15°C, Jet A1 fuel has an average density of 0.805 kg/L. This means:

• 1 litre of Jet A1 fuel weighs approximately 0.805 kg (805 grams).
• In colder temperatures, fuel density increases, making it heavier per litre.
• In warmer temperatures, fuel density decreases, making it lighter per litre.

Accurate fuel weight calculations are crucial for aviation, ensuring proper fuel distribution, aircraft balance, and efficient fuel consumption. Pilots and ground crews rely on density charts to determine precise fuel weight, adjusting for environmental conditions.

Jet A1 Fuel Weight Per Gallon

Jet A1 fuel weight per gallon is another essential factor in aviation fuel management. Since different countries use various measurement systems, understanding the weight of Jet A1 fuel per gallon helps in international aviation operations.

• 1 US gallon of Jet A1 fuel weighs approximately 6.8 pounds (3.08 kg).
• 1 Imperial gallon of Jet A1 fuel weighs approximately 8.1 pounds (3.67 kg).

The difference in weight per gallon depends on the measurement system used. Airlines and fuel suppliers must account for these variations when refueling aircraft for international flights.

Conclusion

Jet A1 fuel plays a crucial role in aviation, with its specifications and weight properties being vital for safe and efficient operations. The stringent standards of Jet A1 fuel ensure its reliability and performance. Understanding the weight of Jet A1 fuel per litre and per gallon is essential for accurate fuel planning and aircraft management. As aviation continues to evolve, fuel efficiency and weight calculations remain key factors in optimizing flight performance. Proper fuel handling, measurement, and planning contribute to the overall safety and effectiveness of air travel worldwide.
