What You'll Learn
Fuel efficiency: 100 miles per gallon per person
The fuel efficiency of an aircraft depends on several factors, including the aircraft's empty weight, payload, engine efficiency, flight path, and weather conditions. The Boeing 747, one of the largest and fastest commercial jets, has a fuel capacity ranging from 48,400 gallons to 63,034 gallons. At cruising speed, it burns approximately 3,500 to 3,800 gallons of fuel per hour, or about one gallon every second. This high fuel consumption translates to a fuel economy of around 0.18 to 0.19 miles per gallon.
However, when considering fuel efficiency per person, the 747 becomes more competitive. With a maximum seat capacity of around 568 passengers, the fuel consumption per passenger improves significantly. For example, on a flight from New York to Los Angeles, each passenger's fuel consumption was estimated at 27 gallons. In comparison, a typical car with two passengers travelling the same distance would consume 56 gallons per person, more than double that of the 747.
The high passenger capacity of the 747 helps distribute the fuel consumption across a larger number of people. Qantas Airways' 747-400 aircraft, with a capacity of 364 passengers, achieves 65.5 miles per gallon per passenger. This number improves further when compared to the average car's mileage of 50 miles per gallon. As a result, each person in the car is responsible for 100 miles per gallon, making the 747 surprisingly fuel-efficient in terms of passenger mileage.
While the 747 may not be the most fuel-efficient aircraft when considering overall fuel burn, its ability to carry a large number of passengers evens out the fuel consumption per person. This efficiency becomes more apparent when comparing it to a typical car with far fewer occupants. As sustainability and climate change concerns gain traction, it is essential to consider not just the absolute fuel burn but also the efficiency achieved per passenger.
In summary, while the Boeing 747 may have a high fuel consumption rate, its fuel efficiency in terms of miles per gallon per person is impressive. With a large passenger capacity and the ability to cover long distances, the 747 can achieve similar or better fuel efficiency per passenger when compared to a typical car. This perspective highlights the complex nature of fuel efficiency calculations and the importance of considering various factors beyond simple miles per gallon.

Fuel type: kerosene-based jet fuel
Kerosene-based jet fuel is used for large planes because kerosene has a higher flash point than gasoline, making it more efficient and powerful. The Boeing 747 is a large plane with four engines that burn kerosene-based jet fuel.
The amount of fuel burned by a 747 depends on various factors, such as the number of passengers, the make and model of the engines, and the speed and distance of the flight. On average, a 747 burns about one gallon of fuel per second, or 3,500 to 3,800 gallons per hour, at cruising speed. This equates to around 5 gallons of fuel per mile or 0.18 miles per gallon.
The 747's fuel capacity also varies by model. The 747-100, launched in 1969, holds 48,400 gallons of jet fuel. The 747-200 and 300 models increased this capacity to 52,410 gallons. The 747-400, a popular choice among airlines, can hold 57,285 gallons of fuel, a 9% increase over its predecessors. The latest version, the 747-8, utilizes 787 Dreamliner technology and has a capacity of 63,034 gallons for passenger models and 59,734 gallons for cargo variants.
The high fuel consumption of the 747 is facilitated by its large fuel capacity, enabling it to operate on long-haul international routes. For example, a 747 can fly from New York to London with its standard fuel capacity. However, longer routes, such as Los Angeles to Sydney, require even more fuel.
The fuel efficiency of the 747 has been a topic of discussion. While some consider it inefficient compared to other aircraft, experts have argued otherwise, considering its maximum load capacity of around 568 people. For instance, a flight from New York to Los Angeles with 200 passengers burned 5,325 gallons of fuel in 6 hours, resulting in an estimated fuel consumption of approximately 27 gallons per person.
