How much fuel does a 747 use?

Fuel Consumption of the Boeing 747

The Boeing 747, a renowned wide-body airliner, is known for its exceptional range and passenger capacity. However, its impressive capabilities come at a significant cost in terms of fuel consumption.

During cruising at optimal altitudes, the 747’s four engines consume an astonishing 10-11 tonnes of fuel per hour. This equates to approximately one gallon of fuel every second, highlighting the aircraft’s immense fuel requirements.

To accommodate this massive fuel consumption, the 747 is equipped with an extensive fuel system. Its tanks can hold a staggering 238,604 liters of jet fuel, enabling it to sustain extended flights. This substantial fuel capacity allows the aircraft to navigate long distances, with a maximum range of approximately 7,790 nautical miles.

The 747’s fuel consumption is influenced by various factors, including the aircraft’s weight, altitude, and weather conditions. Heavier loads and higher altitudes necessitate greater fuel consumption, while favorable weather conditions can result in more efficient fuel utilization.

Despite its high fuel consumption, the 747 remains a popular choice for airlines due to its exceptional range and capacity. Its ability to ferry large numbers of passengers across vast distances makes it a valuable asset in the aviation industry. However, the aircraft’s environmental impact and ongoing fuel price concerns have led to the development of more fuel-efficient aircraft designs in recent years.
