Fuel burn rate varies by aircraft type, size, and weight
The fuel burn rate of an aircraft depends on several factors, including the type, size, weight, speed, altitude, weather conditions, and the number of take-offs and landings. The weight of the aircraft, including fuel, passengers, cargo, etc., is a crucial factor in determining fuel burn.
The fuel burn rate varies significantly between different types of aircraft. For example, the Bombardier Global 7500, an ultra-long-range private jet, burns 528 gallons of fuel per hour, while the Embraer Phenom 300 light jet consumes 183 gallons per hour. Light jets, as a category, can burn anywhere between 134 and 222 gallons of jet fuel per hour, depending on the specific aircraft.
The size of the aircraft also plays a role in fuel efficiency. Larger planes tend to have longer ranges and can carry more fuel, which affects their average fuel burn rate. For instance, the Airbus A380, the largest passenger aircraft, consumes 4,600 gallons of fuel per hour, while the Boeing 787-9 burns approximately 2,700 gallons per hour. The Airbus A350, a newer aircraft, is more fuel-efficient than its predecessors, with a fuel consumption of 38 lb of fuel per nautical mile.
Additionally, the weight of the aircraft impacts its efficiency. Very long non-stop flights are affected by the weight penalty of the extra fuel required, often resulting in a reduction in the number of available seats. For instance, Singapore Airlines' former New York to Singapore route could only accommodate 100 passengers (all business class) due to the high fuel requirements for the 10,300-mile journey.
Other factors, such as speed and altitude, also come into play. Jet engines become more fuel-efficient at higher altitudes, and weather conditions like flying into a headwind can increase fuel consumption. Take-off and landing are the most fuel-intensive parts of a flight, so shorter flights with multiple take-offs and landings burn more fuel proportionately.
Overall, the fuel burn rate of an aircraft is influenced by a combination of factors related to the type, size, and weight of the aircraft, as well as operational factors such as speed, altitude, and weather conditions.

Fuel costs: price per gallon and surcharges
Fuel costs for jets can vary significantly depending on various factors, including the type of aircraft, the length of the flight, the number of passengers and baggage, the airport, and the state. For example, on May 11, 2022, the IATA per-gallon price was $4.82 in North America, $4.01 in Europe, and $3.55 in Asia. On the same day, jet fuel prices at specific airports varied, with prices at Boston's Hanscomb Field Jet ranging from $9.79 to $13.38 per gallon, while prices in Oklahoma City were as low as $7.05 per gallon.
The cost of jet fuel has risen in recent years, impacting airlines and carriers. For instance, a transatlantic flight from New York to London on an Airbus A350 XWB would cost nearly $110,000 in fuel, considering the average price of $6.46 per gallon. As a result, airlines have had to increase ticket prices to cope with the additional expenses.
The amount of fuel burned by a jet aircraft during a flight can be significant. For example, a Boeing 747 quadjet burns up to one gallon of fuel every second, resulting in 18,000 gallons of fuel consumed during a five-hour flight. The Airbus A380, the largest passenger aircraft, consumes slightly more fuel, using 4,600 gallons of fuel per hour and approximately 23,000 gallons for a five-hour flight.
To calculate the fuel cost per hour for a jet, you can multiply the fuel consumption per hour in gallons by the current per-gallon cost of jet fuel. This calculation can be done using resources like Conklin & de Decker's flight manuals, which provide recommended cruise speeds and consider factors such as start, taxi, and take-off fuel. However, it's important to note that operators may have their own estimates of hourly fuel consumption based on actual operating data, and the cost of fuel can vary by airport and state.

Fuel efficiency: improvements over time
Fuel efficiency in aircraft has improved significantly over time. Between 1967 and 2007, jet airliners became 70% more fuel-efficient, with a 40% improvement in engine efficiency and 30% from airframes. From 1968 to 2014, the average fuel burn of new aircraft decreased by approximately 45%, translating to a compound annual reduction of 1.3%.
The rate of improvement has varied over the years, with the 1980s seeing a 2.6% annual increase in average fuel efficiency. In contrast, little to no progress was evident during the 1970s and the period from 1995 to 2005. Despite these gains, manufacturers are still behind the United Nations' fuel efficiency targets for new aircraft.
The drive for fuel efficiency has led to the adoption of various technologies and design changes. For instance, Airbus has been using wingtip fences and Sharklet blended-winglets since 1985 and 2009, respectively. These additions increase the effective wing aspect ratio, improving the lift-to-drag ratio and resulting in a 3.5% fuel burn reduction on flights over 2,800 km.
Another strategy to enhance fuel efficiency is to design aircraft for subsonic rather than transonic speed. Research indicates that a subsonic aircraft with turboprop propulsion would save 21% of fuel compared to a conventionally designed aircraft. Similarly, an analysis comparing the Airbus 320 with a hypothetical turboprop successor showed that the slower aircraft would consume 36% less fuel.
Additionally, newer aircraft models are more fuel-efficient than their older counterparts. Aircraft like the Boeing 787 Dreamliner, Airbus A350, and Bombardier CSeries are 20% more fuel-efficient per passenger kilometre than previous generations. However, the transition to newer, more efficient jets can be gradual due to the significant investments airlines have made in their existing fleets.

Jet fuel vs. diesel: high vs. low sulfur content
The amount of fuel burned by a business jet during warm-up varies depending on the aircraft type and other factors such as weight, flight length, and weather conditions. For example, the Bombardier Global 7500 burns 528 gallons per hour, while the Embraer Phenom 300 light jet consumes 183 gallons per hour.
Now, when it comes to jet fuel versus diesel, the key distinction lies in their sulfur content:
Jet fuel and diesel are similar in many ways, and jet fuel even contains more sulfur than diesel, with up to 1,000 parts per million (ppm) of sulfur. This higher sulfur content gives jet fuel better lubricity and currently doesn't require a lubricity additive, unlike diesel fuels. However, due to EPA regulations, refineries are treating jet fuel to reduce its sulfur content, which may impact its lubricating abilities.
Diesel fuel, on the other hand, comes in two main varieties: high-sulfur diesel (HSD) and low-sulfur diesel (LSD). HSD, also known as regular diesel, has been used for decades and contains up to 5,000 ppm of sulfur. However, due to its contribution to air pollution, the EPA has set stricter regulations, limiting on-road diesel fuel to 15 ppm of sulfur since 2006. This type of diesel is now primarily used in off-road, marine applications, and older diesel engines.
LSD, also referred to as ultra-low sulfur diesel (ULSD), contains no more than 15 ppm of sulfur and is mandated for all on-road engines manufactured after 2007. It offers several advantages over HSD, including better fuel efficiency due to cleaner burning, improved engine performance, and reduced emissions of particulate matter, nitrogen oxides, and sulfur dioxide.
The choice between jet fuel and diesel depends on the specific application and engine type. Jet fuel is designed for aircraft engines, while diesel is used for ground transportation and some marine applications. The sulfur content is a critical factor in fuel selection, with low-sulfur options gaining popularity due to their environmental benefits and improved engine performance.

Fuel-efficient aircraft: twin jets vs. quadjets
The debate between twin jets and quadjets has been a topic of interest for many years, with both types of aircraft offering distinct advantages and disadvantages in terms of fuel efficiency. While quadjets have historically dominated the skies, the shift towards more sustainable aviation has led to a decline in their popularity. This is because quadjets, by design, have to accommodate four engines, which results in higher fuel consumption compared to twin jets.
A notable example of the fuel efficiency difference between twin jets and quadjets can be seen when comparing the Boeing 787 'Dreamliner' family with the older 747s. The Qantas airline found that the twin-engine 787 consumes around 2.5 fewer litres of fuel per kilogram of payload than the 747. This may not seem like a significant difference, but when applied to long-haul flights, it can result in substantial fuel savings. For instance, during a five-hour flight, a Boeing 747 quadjet burns 18,000 gallons of fuel, which is equivalent to one gallon of fuel every second. In contrast, the Airbus A350, a modern twin-engine aircraft, consumes 38 lb of fuel per nautical mile.
Twin jets have become increasingly popular due to their improved fuel efficiency. Over time, advancements in engine efficiency and airframe design have contributed to significant reductions in fuel consumption. Between 1967 and 2007, jet airliners became 70% more fuel-efficient, with a 45% reduction in average fuel burn from 1968 to 2014. This trend is expected to continue as the aviation industry strives for more sustainable practices.
However, it is important to consider the trade-offs between twin jets and quadjets. While quadjets consume more fuel, they offer greater contingency in the event of engine failure. With four engines, the likelihood of a complete power loss is lower compared to twin jets. This added reliability may be a crucial factor for certain operations or routes.
In summary, when comparing fuel efficiency, twin jets outperform quadjets due to their lower fuel consumption. The reduction in the number of engines leads to significant fuel savings, especially on long-haul flights. However, quadjets provide additional engine redundancy, which can be a critical factor in specific scenarios. As the aviation industry continues to prioritise sustainability, the development of more fuel-efficient aircraft will play a pivotal role in reducing emissions and minimising the environmental impact of air travel.
