The Boeing 747 achieves 100 miles to the gallon per passenger
The Boeing 747 is a quadjet aircraft that consumes a significant amount of jet fuel, with estimates ranging from 18,000 gallons for a five-hour flight to 36,000 gallons for a ten-hour flight. However, when we consider the number of passengers it can carry, the fuel efficiency per passenger improves considerably.
The Boeing 747 is a large aircraft that can carry a substantial number of passengers, with a maximum capacity of around 568 people. Let's use a more conservative estimate of 500 passengers to simplify the calculations. Now, let's consider the fuel consumption of the 747. On average, it burns about one gallon of fuel per second, which equates to five gallons of fuel per mile.
When we divide the number of gallons burned per mile by the number of passengers, we find that the 747 consumes 0.01 gallons of fuel per passenger per mile. This means that for every gallon of fuel burned, each passenger travels 100 miles. In other words, the Boeing 747 achieves 100 miles to the gallon per passenger.
This fuel efficiency per passenger is notably higher than that of a typical car, which averages 25 miles per gallon. For example, consider a drive from New York City to Los Angeles, which is approximately 2,797 miles. With an average car occupancy of two passengers, the trip would consume 56 gallons of fuel per person. In contrast, flying the same route in a Boeing 747 with 200 passengers would result in a fuel consumption of 27 gallons per person, demonstrating the improved efficiency of the 747 in terms of fuel usage per passenger.
While the Boeing 747 may not be the most fuel-efficient aircraft compared to newer models, its ability to transport a large number of passengers contributes to its impressive fuel efficiency per passenger.
